Lifting Columns |7Important information
LINAK® products, within the scope of this manual, are not classified as medical electrical equipment or systems, nor do they fall within the scope of the EU Medical Device Directive/Regulation or other similar national regulations. The products are components to be built into a piece of medical electrical equipment by amanufacturer.
To support the assessment and certification task of the complete medical electrical equipment or systemworldwide, LINAK provides certification, on a component level, according to the IEC 60601-1, (Medical
electrical equipment – Part 1: General requirements for basic safety and essential performance) as recognised
components by NRTL (Nationally Recognized Testing Laboratories).
Description of the various signs used in this manual:Warnings
Failure to comply with these instructions may result in accidents involving serious personal injury.

Recommendations
Failing to follow these instructions can result in product damage.
Please read the following safety information carefully:
Ensure that all staff who are to connect, mount, or use the actuator system are in possession of thenecessary information and that they have access to these assembly instructions.
Persons who do not have the necessary experience or knowledge of LINAK products should not use these.
Moreover, persons with reduced physical or mental abilities must not use the products, unless they are

is responsible for the safety of these persons. Moreover, children must be under surveillance to ensure thatthey do not play with the product.
Please be aware that LINAK has taken precautions to ensure the safety of the actuator system. The
manufacturer/OEM is responsible for the overall approval of the complete application.
LINAK recommends to use the actuators in push applications rather than pull applications.

LINAK actuators are not to be used for repeated dynamic push-to-pull movements.
For general pull applications or repeated dynamic push-to-pull movements in the application, please contact
LINAK A/S if in doubt.
LINAK actuators and electronics generally fall outside the IEC 60601-1 definition of applied parts and are notmarked as such.
However, assessing the risk whether actuators and electronics can unintentionally come into contact
with the patient, determines that they are subject to the requirements for applied parts. All the relevant
requirements and tests of the standard are carried out as part of the IEC CB* Scheme/NRTL** assessment.
* CB: Certification Body**NRTL: Nationally Recognised Testing Laboratory

Lifting Columns |8General warnings
Failure to comply with these instructions may result in accidents involving serious personal injury:
The medical device manufacturer is responsible for the incorporation of a suitable safety
arrangement, if the actuator or lifting column is used for pull in an application where personal injury
can occur, which will prevent personal injury from occurring in case of actuator failure.
Note that during construction of applications, in which the actuator is to be fitted, there must be no
possibility of personal injury, for example the squeezing of fingers or arms.
The plastic parts in the system cannot tolerate cutting oil.

Assure free space for movement of the application in both directions to avoid a blockade.

The application and actuators are only to be operated by instructed personnel.

In applications with spline function, the blockage by an obstacle when the application is moving
inwards, the removal of the obstacle will cause the load to drop until the spindle hits the nut.
Do not turn the outer tube.

Do not use chemicals.

Inspect the actuator system regularly for damage and wear.

Do not expose LINAK actuator system components to high intensity ultraviolet radiation disinfection
lamps. This may damage the enclosure, supporting parts and cables.

If faults are observed, the products must be replaced.

Lifting Columns |9

A LINAK control box, actuator and accessory component must, in the final application, be placed
where it is not exposed to any impact. This is to prevent damage if a passer-by accidentally hits itwith an object or when cleaning the floor with a broom or a mop. On a medical bed e.g. this might
be underneath the mattress support platform. If necessary to mitigate this risk, additional protection
might be required.
To avoid unintended movement, prevent foreign objects or persons from unintentionally activating afootswitch or a hand control at any time, for instance during normal use or maintenance.
If there is visible damage on the product it should not be installed.

If the actuator system makes unusual noise or smells, switch off the mains voltage immediately anddisconnect batteries, if applicable.
The products must only be used in an environment that corresponds to their IP protection class.

The cleaners and disinfectants must not be highly alkaline or acidic (pH value 6-8). See cleaning
section.
Irrespectively of the load, the duty cycle stated on the product label must NOT be exceeded.

The control box must only be connected to the voltage stated on the label.

Systems not specified for pull must only be used in push applications.

Fastening screws and bolts must be tightened correctly.

Electromagnetic Compatibility (EMC)
EMC Warnings
Electromagnetic compatibility – general
LINAK® actuator systems bear the CE marking as an attestation of compliance with the EMC Directive
2014/30/EU. The systems are designed to meet all requirements of applicable standards and havebeen tested to meet IEC 60601-1-2 requirements.
Emission:
LINAK Actuator Systems are CISPR 11, Group 1, Class B products, comply with IEC 61000-3-2, Class
A and IEC 61000-3-3 unless stated otherwise in the relevant section of this document.
Immunity:
Test levels are according to Professional Healthcare Facility and Home Healthcare Facility Environment.
Electromagnetic phenomena are evaluated on a system level, with the actuator connected to a LINAK
control box and accessories.
LINAK always recommends to perform verification tests on the final medical device.
Electromagnetic compatibility – third party components
Use of accessories, transducers and cables other than those specified by LINAK could result inincreased electromagnetic emissions or decreased electromagnetic immunity of the actuator system
and result in improper operation.
Electromagnetic compatibility – interference with other equipment in general
Use of the actuator system adjacent to or stacked with other equipment should be avoided as
this could result in improper operation. If such use is necessary, the actuator system and the otherequipment should be observed to verify that they are operating properly.
If the user notes unusual behavior of the actuator system, in particular if such behaviour isintermittent and associated with the standing right next to mobile phones, microwaves and radio
broadcast masts, this could be an indication of electromagnetic interference.
If such behaviour occurs, try to move the actuator system further away from the interfering
equipment.
Electromagnetic compatibility – interference with other equipment, RF communications
Portable RF communication equipment (including peripherals such as antenna cables and externalantennas) should be used at a distance no closer than 30 cm (12 inches) to any part of the actuatorsystem. This also applies to cables specified by the manufacturer. Otherwise, a performancedegradation of this equipment could result.

Lifting Columns | 14

EMC responsibilities for LINAK actuator systems
LINAK verifies the EMC performance of each LINAK product and approves them individually. The LINAK
products can be combined and integrated into many different systems. LINAK also verifies the system EMC
performance on commonly used combinations.
LINAK has certificates in accordance with applicable standards for each product and provides the customers,
who are building the application and integrating these products into systems (systems with control box,
actuators, cables, batteries, etc.), with these certificates.
However, EMC testing of LINAK products in generic LINAK systems is not made in an environment that
corresponds to the specific application environment which differs from the generic testing environment.
There will be differences that can affect the EMC performance in the specific target application.
The customer is responsible for qualifying and approving the complete application including the LINAK
system.
Regulatory standard
LINAK products, being components to be incorporated by a Manufacturer [definition: IEC 60601-1 ed.3.1,
cl. 3.55] into Medical Electrical Equipment [definition: IEC 60601-1 ed.3.1, cl. 3.63], are tested concerning
the EMC phenomena according to the Collateral Standard IEC 60601-1-2 ed. 4.1.
IEC 60601-1-2 ed. 4.1 sets forth the requirements for the electromagnetic compatibility of Medical Electrical
Equipment, ensuring that devices operate safely and effectively within their intended environments.
Compliance with this standard is essential to minimize electromagnetic interference and maintain the
integrity and performance of Medical Devices.
Furthermore, IEC 60601- 1-2 ed. 4.1 states:”This collateral standard recognizes that the Manufacturer has the responsibility to design and perform
Verification of Medical Electrical Equipment and Medical Electrical Systems to meet the requirements of thisCollateral Standard and to disclose information to the Responsible Organization or Operator so that the
Medical Electrical System will remain safe throughout its Expected Service Life.”
Qualification process of a new application
The qualification process for a new application is normally done in cooperation between the customer and
LINAK. LINAK provides the relevant support, competence and documentation needed for the customer’s
overall development plan and test plan for the specific application.
The driver of the qualification process is the customer who has the ultimate application responsibility (MDS).
The customer identifies and specifies the needed testing based on many different parameters (experience,risk management, requirements from standards, etc.).
In many cases, the customer is establishing and verifying tests early in the project to ensure that the approval
process has a low risk of failing when tested in the approval institute.
The customer identifies which tests to make and when they are to be performed in the project to mitigate
the risk of failure in the approval process which also includes EMC testing.

Lifting Columns | 15

Electrostatic discharge (ESD)
LINAK® considers ESD to be an important issue and years of experience have shown that equipment
designed to meet the levels specified in standards might be insufficient to protect electronic equipment incertain enviroments.
1. Handling and mounting electrostatic discharge sensitive devices (ESDS devices).
• Handling of sensitive components shall only take place in an ESD Protected Area (EPA) under protected
and controlled conditions.
• Wrist straps and/or conductive footwear (personal grounding) shall always be used when handling ESDS
devices.
• Sensitive devices shall be protected outside the EPA by the use of ESD protective packaging.
2. Responsibility LINAK/customer• ESDS devices must under no circumstances, during transport, storage, handling, production or mounting
in an application, be exposed to harmfull ESD.
• LINAK can only guarantee the lifetime of ESDS devices if they are handled in the same way fromproduction at LINAK A/S until they are mounted in the manufacturer’s application. It is therefore
important that the ESDS devices are not removed from the ESD protected packaging before they arephysically within the EPA area at the customer premises.

Batteries
General battery warnings
Handle batteries carefully. Do not short circuit the battery.

Avoid continuous battery discharge when the medical device is not in use, as this may cause leadsulphate formation, which, if left in this state for too long, will irreversibly damage the battery.
LINAK battery packs may emit flammable gases. Do not expose the battery packs to fire or
equipment that emits sparks. Moreover, do not store the battery in a closed environment orincorporate it into a closed structure of an enclosure as this may cause an explosion, fire, equipment
damage, or injury.
Handle tools carefully and do not wear jewelery when handling batteries. A short-circuit of thebattery terminals can cause burn injuries, damage or trigger explosions.
Only connect LINAK batteries to compatible chargers.

LINAK battery packs contain toxic substances. If the internal battery fluid leaks out and gets onto
skin or clothing, make sure it is washed off with clean water. Moreover, if the fluid gets into the eyes,
rinse them immediately with clean water and seek medical assistance.
Do not use or store LINAK battery packs in places where the ambient temperature exceeds 50 °C,
such as inside a hot automobile, in direct sunlight, or in front of a stove or a source of intense heat.
Doing so can shorten the battery life, lower its performance level, cause the battery to leak fluid,
explode, cause fire, or be damaged.

Lithium ion batteries
Li-Ion batteries are moving in the direction of minimising the physical size and, at the same time, increasing
the capacity. This gives a very compact battery with a high energy concentration. It also increases the risk ofthermal runaway (see note below) due to internal short circuits.
The general use of Li-Ion batteries has increased, and the inherent risk of thermal runaway has led to stricter
rules within the transport industry, specifically air transport with tightened restrictions on the quantity,
handling, and storage of specific products.
The OEMs and consumers must recognise that although safe to use, Li-Ion cells always have a very small riskof thermal runaway. The risk could be as little as 1 PPM or even less.
LINAK currently bases our Li-Ion battery design on cell types with an industry-proven history (e.g. electriccars). The use of well-proven cell technology reduces the risk of thermal runaway, but it does not eliminate
it. LINAK has completed activities to reduce this risk and the complete battery package is approved inaccordance with UL.
An external, internationally recognised expert has also reviewed the design to ensure that it is manufactured
according to the latest recommendations. Further to that, we only use cells from well-recognised
manufacturers.
LINAK recommends that when using Li-Ion batteries, the customers should carry out proper risk analysis on
their application. The risk analysis must also take into consideration that these products are not mounted inpositions where they are in direct contact with flammable materials.
LINAK Li-Ion batteries have no greater risk of thermal runaway than other Li-Ion cells from well-recognised
manufacturers within the market. Therefore, LINAK cannot take responsibility for any failures that occur due
to a failure that is inherent in the nature of Li-Ion batteries.
If any of the Li-Ion batteries built into LINAK products are found to be defective under warranty, LINAK will
provide the OEM with a new product. LINAK explicitly disclaims all other remedies. LINAK shall not in any
event be liable under any circumstances for any special indirect punitive incidental or consequential damages
or losses arising from any incident related to the inherent risk of thermal runaway in the Li-Ion cell and any
use of LINAK products. Moreover, LINAK explicitly disclaims any responsibility for profit loss, failure to realise
expected savings, any claim against our customer by a third party, or any other commercial or economic
losses of any kind, even if LINAK has been advised of the possibility of such damages or losses.
Note: ‘Thermal runaway’ is overheating of a cell, and it could lead to a small fire and smoke from the cell.

Transportation
The lithium ion batteries must be packed and transported in accordance with applicable regulations. Always
ask your local transportation provider how to handle the transportation of lithium ion batteries.
Please see the general assembly instructions and the mounting section for detailed information.

Lifting Columns | 21

Warnings
When using Li-Ion batteries with patient lift control boxes, loss of power might happen due to thebattery deep discharge protection. This will only happen in case of continuous battery use despite
warnings. In this event, there may be no warning, and the application may not be able to move when
expected.
In his risk analysis, the customer must take into consideration how to assure alternative means tomake movement, for instance quick release or manual lowering.
Do not open the battery housing as damaging the cell or circuitry may develop excessive heat.

If product caution is not clearly visible at low light intensity, read the product label instructions
symbol. A warning must be included in the application manufacturer manual for the medical device.
The application manufacturer must test the application and ensure that intentional and unintended
operations do not exceed the battery specification limits.
Defective or damaged Li-Ion batteries are not allowed for transportation.

For safety reasons, please adhere to the indicated charging and operation temperature.

In case the battery is too hot, disconnect it, evacuate the room, and wait for 2 hours before taking
further steps.
Mounting instructions must be followed in order to avoid exposing batteries to water.

In general, recharging of battery must take place every 6 months. However, please note:- New Li-Ion batteries, shipped from LINAK are in a deep-sleep state, where the self-discharge is very
little- When mounted in an application, LINAK Li-Ion batteries wake up, resulting in a higher rate ofcharge, depending on the application/system- Application manufacturer must consider this idle consumption for his specific system and makeprecautions to avoid discharged batteries.
- Contact your LINAK sales team for further information
If batteries are to be shipped by air, they shall not be charged to more than 30%

Disposal of the battery takes place in accordance with local regulations.

Lifting Columns | 22

Recommendations
Do not exceed the storage temperature as it will shorten the product life and performance.
Allow the battery to settle to room temperature before use.
Lithium ion batteries are not intended for use in outdoor applications and indoor pool environments.
If the battery is completely discharged, then recharge the battery before storage.
Always use correct LINAK charger
DO NOT:
Heat or burn the batteries.
Expose the batteries to high impact/excessive force.
Crush or puncture the batteries.
Use batteries with signs of damage or corrosion.
Charge or store the batteries near combustible material.
Exceed IP-ratings.
Overcharge or fully discharge the batteries.

Safety feature
Lithium ion batteries contain several mechanisms to protect themselves from being damaged due toexcessive use. In case of overheating, the device will activate a thermal protection. No power output will beavailable until the temperature is again within normal operating range.
Overheating may occur by extensive use at high temperatures or when exceeding the duty cycle (see productlabel).

Lead acid batteries
Maintenance of batteries
Prior to first use of LINAK® batteries, please make sure that they are charged at least 24 hours and if possible
even longer for proper functioning and prolonging the battery lifetime.

Replacement of batteries
The batteries must only be replaced by the same type of batteries or mechanical and electrical equivalent
types. The batteries must be new or maintained by means of charging at least every 6 months. The batteries,
which make a set, must be supplied with identical production codes.
Production code mismatch may lead to a severely reduced lifetime expectancy.
Before mounting, ensure that the battery set is correctly connected, compare with the drawing in the battery
room and check that no connectors are loose.

Warnings in connection with battery replacement
Please observe the following maintenance, replacement, and disposal requirements to ensure a safeand reliable operation.
The batteries are to be replaced after 4 years at the latest. Perhaps earlier, depending on the patternof use. Frequent and high-powered discharges reduce the battery life. For an optimum lifetime, theproduct must be connected to the mains voltage as often as possible. It is recommended that thebatteries are to be charged for at least every 6 months - otherwise the batteries will have reduced
capacity due to self-discharge. It is recommended to test the battery function at least once every year.
The battery compartment is hermetically separated from the electronics compartment. Whenreplacing the batteries this separation must not be damaged or modified as this may allow
penetration of battery gas into the electronics compartment with risk of explosion.
When replacing batteries in waterproof products (IPX5 and IPX6), precautions must be taken thatthe sealing material (silicone ring or joint filler) is not damaged and that it is correctly placed in thegroove. Hereafter, the screws in the cover are to be fastened with approx. 1 Nm.
If necessary, replacement sealing is available at LINAK.
The battery compartment is supplied with ventilation that ensures correct and necessary airing of thebattery compartment. This airing must not be blocked or covered as a positive pressure may occur
with risk of explosion.
If the product has been exposed to mechanical overload (lost on the floor, collision/squeezing in theapplication or a powerful stroke), the product must be sent to an authorised workshop for control of
the hermetic separation between the battery and electronics compartment.

Disposal
Lead acid batteries must be disposed of in the same way as car batteries. Alternatively, they may be returned
to LINAK.

IPX6 Washable DURA™
Description of washing test
LINAK washable products frequently go through a fully controlled washing test. The LINAK term “IPX6
Washable DURA” signifies that the products conform exclusively to this test.
The “IPX6 Washable DURA” washing test is used to ensure that products that are rated “IPX6 Washable
DURA” comply with the agreed terms and conditions. This washing test differs from the norm EN60601-252 as the products are not aged and each washing cycle is followed by a 30 minute cooling process.
Further information regarding the washing process can be found in the German document “Maschinelle
Dekontamination” from the organisation AK-BWA .
Estimated time
consumption:

Approximately 1 month.

Amount ofsamples:During the development process, the number of tested samples is in accordance with
GP082. During running production, the number of tested samples complies with
UM-41-22-001.

General:The process applies to the IPX6 Washable DURA system.

Test conditions: • The units are not aged.
• Products with adhesive foils must be hardened before ageing.
• The hardening time depends on the used adhesive, but is typically 3 days at 20°C.
• The units are washed with new plugs/cables.
• The cables should be as long as possible and free ends should be shut off.
• Detergent and rinsing aids used:- Detergent 1: Ecolab Sekumatic FRE- Rinsing aid 1: Ecolab Sekumatic FKN (Neutral Rinse Aid).
Test procedure:• The units are placed in the washing machine in the intended mounting direction(in the most sensible direction regarding water penetration, if this is not the same
direction).
• The washing process (see picture below) is repeated 11 times and consists of:- Washing with 0.3 % alkaline detergent for 2 minutes in 70 °C hot water.
(Note: the temperature is measured in the tank, not necessarily at the unit).
- Rinsing with neutral rinsing aid for 20 seconds.
- Drying and cooling for 30 minutes in the open air at approx. 20 °C.
• After 11 cycles, the products are left in a ventilated room for 24 hours. The above
steps are repeated until a total of 250 cycles has been reached.
• Immediately after washing and after further 24 hours, the products are subjected to ahigh voltage test in accordance with UM-31-30-072.
• A population sample of the products is opened for water penetration control
immediately after the washing test.
Accept criteria are in accordance with UM-20-30-002.

Options:

The following options can be used for the test:• The units may be weighed prior to and after the washing test to detect water.
• The bubble test may be used to detect any leakages.
• X-ray may be used to detect any leakages.

Recommendations• Please follow the important BL1 mounting guidelines.
• Max. storage temperatures: +50 °C.
• BL1 is for use in push applications, cable outlet from smallest profile (top) or biggest profile (bottom).
See top and bottom plate dimensions.
• When washing according to IPX6 parameters, it is not allowed to splash water directly onto the plastic
frames between the profiles. Direct splashing is only permitted on the aluminium profiles. Alternatively,
BL1 can be mounted upside down with the largest profile at the top. In this configuration, no IP rating
applies.

Warnings• BL1 is heavy (9.8 kg). To avoid personal injury, DO NOT DROP
• Do not adjust anything during movement, can cause personal injury• LINAK recommend using a safety nut in medical applications• A broken chain causes a drop of half the length of actual stroke. Therefore do not overload• The BL1 is designed for use in push applications, dynamic “Pull forces” can result in damage to thecolumn and cause collapse of the application.
• Do not loosen any screws on the BL1, this can cause collapse of the column• LINAK recommends making regular measurement of Class 1 protective ground conductivity in theapplication to avoid a disconnected grounding cable. Worn out or defect parts must be replaced.

BL1 mounting guidelines• BL1 is for use in push applications, and can be mounted in both directions (smallest profile down, or up).
Note: The cable outlet can be positioned at the top (smallest profile). If the option with integrated cable ischosen, the cable outlet can also be positioned at the bottom (biggest profile).
No IP rating applies when BL1 is mounted with the largest profile at the top (see illustration).
• It is very simple to mount the BL1 in the application using the 4 mounting holes in both endplates.
• Use 4 self-tapping screws, in each end, for mounting to the application.
Use EJOT PT type DG Ø8, screw depth must be min. 30 mm in aluminium profile.
Screw torque: 15 - 17 Nm.
• If the column has been loosened from the application, it is very important that the self-tapping screws aremounted in the same thread, to ensure the same strength in the thread. Therefore we recommend thatthe screws are loosened no more than 1 or 2 times.
BL1 is for use in push applications to obtain IPX6. The mounting direction must be with the largest profile
down. It is very simple to mount the BL1 in the application using the 4 self-tapping screws in the mounting
holes of both endplates.

Recommendations• The mounting plate in the application must cover the entire top plate of the BL1 and be strong enough tocarry the load.
• Remember to secure the cable mounted in the top of the column to the application, so that it cannot bepulled out of the column. We recommend to use LINAK Cable:- Lock kit for BL1 with motor cable: 0808040- Lock kit for BL1 with hand control cable through: 0808046
Use only the screws included in the kit.
• For motor cable mounted at the top, use the long screw with the coarse thread.
Screw torque 1.7 Nm.
• For motor cable mounted at the bottom and for cable through, use the short screw with the fine thread.
Screw torque 2.7 Nm.
• Electro Static Discharges!
There is no electrical connection through the length of the BL1 column. Therefore, to avoid ESD issues,consider external potential alignment between the top and bottom of the bed frame.
To connect for further earth wiring in the application, use an appropriate ø8 mm cable shoe under one of
the 8 mm screws at both the top plate and the bottom plate.
• Remember to mount the blind plugs in the top plate if the motor cable is connected from the bottom
plate to ensure the IPX6 protection.

Lifting Columns | 41
When mounting more than one BL1 you need to consider the fixation:
Fixed pivot point

Moveable pivot point

Fixed pivot point

Fixed pivot point

Example 1.

Example 2.

The reason why it is important only to fix one column, is that the columns will not move exactly in parallel –even if you have positioning such as hall.
If more than one column is fixed it can lead to dangerous situations.

If you have a trend/anti-trend function in your application, you need to mount one or more BL1s with aslider.
Having sliders prevents the column from bending as illustrated below.

Mounting guideline for two LC1 columns in application
When mounting more than one LC1 you need to consider the fixation:
The reason why it is important only to fix one column is that the columns will not move exactly in parallel –even if you have positioning such as Hall.
If more than one column is fixed, it can lead to dangerous situations.

If you have a trend/anti-trend function in your application, you need to mount one or more LC1 columns
with a slider.
Sliders prevent the column from bending as illustrated below.

Lifting Columns | 49

Recommendations• Be aware to mount the cable plug correctly. The cable slot must fit into the socket.
• Remember to secure the cable mounted in the top of the column to the application so that it cannot bepulled out of the column. We recommend to use LINAK cables:•

Lock kit for Mini-Fit cable: 1053W8011•

Lock kit for hand control cable through: 1053W8021- Use only screws that are included in the kit. Screw torque = 2 Nm

• The cables coming out of the side of the column should follow the guidelines below. The internal radius
should not be less than 3 times the outer dimension - OD - of the cable. If the outer cable dimension isØ7 for instance, the internal radius of the maximum cable bending is 21 mm.

LC1 - protective grounding cable• LC1 has potential equalisation between top and bottom plate but the middle profile is not grounded.
• It is recommended to use screws with thread-lock adhesive• Screws of high-quality steel 8.8 or 10.9 must be used to secure safe mounting of the LC1 to theapplication.

LC1 including grounding cable
For medical equipment the impedance between the relevant parts of the application frame and the control
box’s appliance inlet earth pin must not exceed 100 milli Ω. Compliance is checked by passing a current
through the impedance while measuring the voltage drop. The current used for measurement must be• 25 A according to IEC60601-1, ANSI / AAMI ES60601-1• 40 A according to CAN / CSA-22.2 No. 60601-1
The cable can only be considered as a protective grounding cable in compliance with Class 1, if the above
requirements are fulfilled. (Connected Bottom and Top plates) From the control box to the protective earth
pin must not exceed 100 milli Ω (cable impedance). The LC1 with grounding cable is not classified as a
CLASS 1 component, this classification relates to the end-use application. (Medical Device) Application must
always be tested.

Recommendations• Always follow the important LC1 mounting guidelines and LINAK specifications to ensure correctfunctionality.
• LC1 is for use in push applications, cable outlet from (smallest profile) top plate. See top plate
dimensions.
• Always use LINAK compatible components and ensure that the application functionality is tested with allaccessories connected before bringing it into service.
• The mounting plate in the application must cover the entire LC1 bottom plate and be strong enough tocarry the load.
• If LC1 is not mounted/used in vertical position, the internal cable may get squeezed inside the liftingcolumn.
• Regular cleaning is recommended to reduce bacteria and increase the hygiene level. Do not use chemicals
for cleaning.
• When washing according to IPX6 parameters, it is not allowed to splash water directly onto the plastic
frames between the profiles. Direct splashing is only permitted on the aluminium profiles. Alternatively,
LC1 can be mounted upside down with the largest profile at the top. In this configuration, no IP rating
applies.
• The LC1 is intended for indoor use and NOT for use in harsh environments, like for instance pool ormarine environments and agriculture buildings with ammonia vapors.
• Collection of water on the top plate will result in drainage failure.
• Assure free space for movement of application in both directions to avoid blockade.
• Do not expose the column to high intensity ultraviolet radiation disinfection lamps as this may damage
supporting parts and cables.

Lifting Columns | 52

Warnings• The LC1 is heavy and weighs 9.0 kg. To avoid personal injury, DO NOT DROP!
• Always use cable lock to ensure fixation of cables and take care that the cable cannot be squeezed,
pulled or subjected to any other stress or damage.
• Make a proper cable installation and inspect regularly for wear, damage and jarring sound to avoid cableinterruption and actuator defects. Defective parts must be replaced.
• A damaged housing can cause moisture to gather and lead to dangerous electrical connections between
metal parts and wires.
• Always check correct assembly after mounting and service to ensure that the cable locks are mounted.
• Take special precaution concerning third party interfacing. Please contact LINAK® for further information.
• Do not exceed the max. pull load specified on the label.
• Do not add dynamic load when changing between pull and push.
• Do not adjust anything during movement or while connected to mains as this may cause personal injury.
• Interconnecting cables must remain plugged in during cleaning to prevent the ingress of water.
• Be aware that water may enter the lifting column, if cable lock is not used.
• Mount with top late upwards to obtain IPX6.
• After service inspection, the application must be tested for correct functionality before it is brought into
operation to avoid misalignment between two columns moving in parallel.
• LINAK recommends to make regular measurements of Class 1 protective ground conductivity in theapplication to avoid a disconnected grounding cable. If there are worn-out or defective parts, thecomplete LC1 column must be replaced.
• If LC1 is used in ceiling-hang applications, a third party safety device or safety harness must be used toprevent personal injuries.

Mounting of a product on the side of an LC3
It is possible to mount a product on all 4 sides of the LC3 at the same time. However, it requires that theholes for mounting are placed with different distances from the top and/or bottom plate. Otherwise themounting screws will collide.
Minimum distance from the top and bottom plate must be observed.

When mounting more than one LC3 you need to consider the fixation:
The reason why it is important only to fix one column, is that the columns will not move exactly in parallel –even if you have positioning such as hall.
If more than one column is fixed it can lead to dangerous situations.

If you do have a trend/anti-trend function in your application, you need to mount one or more of LC3
columns with a slider.
Having sliders prevents the column from bending as illustrated below.

Recommendations• Please follow the important LC3 mounting guidelines.
• LC3 is for use in push or pull applications, cable outlet from smallest profile (top) or biggest profile(bottom). See top and bottom plate dimensions.
• When washing according to IPX6 parameters please notice that the large profile of the LC3 column must
be placed upwards (bottom up).
• We recommend making a functional test of the application with all accessories connected before putting
it into operation.
• Regular cleaning is recommended to reduce bacteria and increase the hygiene level• Intended for indoor use only
• Not intended for use in harsh environments like e.g. pool environment, marine environment andagriculture buildings with ammonia vapors.
• When washing according to IPX6 parameters, it is not allowed to splash water directly onto the zincframes between the profiles. Direct splashing is only permitted on the retracted aluminium profiles.

Warnings• Always check correct assembly after mounting and service to ensure that the cable locks are mounted.
• Ensure that the cable cannot be squeezed, pulled or subjected to any other stress or damages.
• LC3 is heavy (more than 10 kg). To avoid personal injury and product damage, DO NOT DROP!
• Take special precautions concerning 3rd party interfacing. Please contact LINAK for further information.
• Do not exceed the max. pull load specified on the label.
• Do not add dynamic load when changing between pull and push.
• Do not adjust anything during movement or while connected to mains, it can cause personal injury.
• To avoid cable interruption and actuator defects make a proper cable installation and inspect regularly forwear, damage and jarring sound. Defective parts must be replaced.
• After service inspection, the application must be tested for correct functionality before it is put into
operation, to avoid misalignment between two columns moving in parallel.
• LINAK recommend using a safety nut in medical applications! LC3 has safety nut as standard.
• Do not loosen any screws on the LC3, this can cause collapse of the column!
• LINAK recommends making regular measurement of Class 1 protective ground conductivity in theapplication to avoid a disconnected grounding cable. If there are worn out or defect parts, the complete
LC3 must be replaced.
• Interconnecting cables must remain plugged in during cleaning to prevent the ingress of water.
• Always retract the LC3 column fully to obtain IPX6 protection class.
