Obey the following installation instructions:This device may only be installed and put into operation by qualified personnel. This device does not contain serviceableparts. The tripping of an internal fuse is caused by an internal defect. If damage or malfunction should occur during
installation or operation, immediately turn power off and send unit to the factory for inspection.
Install device in an enclosure providing protection against electrical, mechanical and fire hazards. Install the device onto a
DIN rail according to EN 60715 with the input terminals on the bottom of the device.
Make sure that the wiring is correct by following all local and national codes. Use appropriate copper cables that aredesigned for a minimum operating temperature of +60°C for ambient temperatures up to +45°C, +75°C for ambient
temperatures up to +60°C and +90°C for ambient temperatures up to +70°C. Ensure that all strands of a stranded wire
enter the terminal connection.
The device is designed for pollution degree 2 areas in controlled environments. No condensation or frost is allowed. The
enclosure of the device provides a degree of protection of IP20. The enclosure does not provide protection against spilledliquids.
The device is designed for overvoltage category II zones. Below 2000m altitude the device is tested for impulse withstandvoltages up to 4kV, which corresponds to OVC III according to IEC 60664-1.
The device is designed as “Class of Protection” II equipment according to IEC 61140.
The device is suitable to be supplied from TN, TT or IT mains networks. The continuous voltage between the input terminal
and the PE potential must not exceed 300Vac. A disconnecting means shall be provided for the input of the device.
The device is designed for convection cooling and does not require an external fan. Do not obstruct airflow and do notcover ventilation grid!
The device is designed for altitudes up to 5000m (16 400ft). Above 2000m (6560ft) a reduction in output current is required.

OutputThe output provides a SELV/PELV/ES1 rated voltage, which is galvanically isolated from the input voltage. The output iselectronically protected against no-load, overload and short circuit. In case of a protection event, audible noise may occur.
The output is designed to supply any kind of loads, including inductive and capacitive loads. Capacitive loads should not
be larger than 4 000μF with 1.5A or 5 000μF with 0.75A additional resistive load.
At heavy overloads (when output voltage falls below 14V), the device delivers continuous output current for 55ms. After
this, the output is switched off for approx. 340ms before a new start attempt is automatically performed. This cycle isrepeated as long as the overload exists.
If the overload has been cleared, the device will operate normally.

Hold-up TimeThe hold-up time is the time during which a device’s output voltage remains within specification following the loss of input
power. The hold-up time is output load dependent. At no load, the hold-up time can be up to several seconds. The green

Lifetime Expectancy

The Lifetime expectancy shown in the table indicates the minimum operating hours (service life) and is determined by
the lifetime expectancy of the built-in electrolytic capacitors. Lifetime expectancy is specified in operational hours and is
calculated according to the capacitor’s manufacturer specification.
Please note: The manufacturer of the electrolytic capacitors only guarantees a maximum life of up to 15 years (131 400h).
Any number exceeding this value is a calculated theoretical lifetime which can be used to compare devices.

10. MTBF
MTBF stands for Mean Time Between Failure, which is calculated according to statistical device failures, and indicatesreliability of a device. It is the statistical representation of the likelihood of a unit to fail and does not necessarily represent
the life of a product.
The MTBF figure is a statistical representation of the likelihood of a device to fail. A MTBF figure of e.g. 1 000 000h meansthat statistically one unit will fail every 100 hours if 10 000 units are installed in the field. However, it cannot be determined
if the failed unit has been running for 50 000h or only for 100h.
For these types of units the MTTF (Mean Time To Failure) value is the same value as the MTBF value.

17. Dielectric Strength
The output voltage is floating and has no ohmic connection to the ground.
The output is insulated to the input by a double or reinforced insulation.
Type and routine tests are conducted by the manufacturer. Field tests may be conducted in the field using the appropriate
test equipment which applies the voltage with a slow ramp (2s up and 2s down). Connect all phase-terminals together
as well as all output poles before conducting the test. When testing, set the cut-off current settings to the value in thetable below.
It is recommended that either the (+) pole or the (–) pole shall be connected to the protective earth system. This helps to
avoid situations in which a load starts unexpectedly or cannot be switched off when unnoticed earth faults occur.

21. Application Notes
21.1. CHARGING OF BATTERIES
Do not use the power supply to charge batteries.

21.2. SERIES OPERATIONPower supplies of the same type can be connected in series for higher output
voltages. It is possible to connect as many units in series as needed, providing thesum of the output voltage does not exceed 150Vdc. Voltages with a potential
above 60Vdc must be installed with a protection against touching.
Avoid return voltage (e.g. from a decelerating motor or battery) which is applied
to the output terminals.
Keep an installation clearance of 15mm (left / right) between two power supplies
and avoid installing the power supplies on top of each other.
Pay attention that leakage current, EMI, inrush current, harmonics will increase
when using multiple power supplies.

21.3. PARALLEL USE TO INCREASE OUTPUT POWER
Do not use parallel devices for higher output currents.

21.4. PARALLEL USE FOR 1+1 REDUNDANCYDo not use this device to build redundant systems since there is no monitoring (DC-OK signal) included.

21.5. TWO PHASE OPERATION
The power supply can also be operated on two phases of a three-phase-system.
Such a phase-to-phase connection is allowed as long as the supplying voltage isbelow 240V+10%.
Ensure that the wire, which is connected to the N-terminal, is appropriately fused.

21.6. USE IN A TIGHTLY SEALED ENCLOSURE
When the power supply is installed in a tightly sealed enclosure, the temperature inside the enclosure will be higher thanoutside. In such situations, the inside temperature defines the ambient temperature for the power supply.
The power supply is placed in the middle of the box, no other heat producing items are inside the box. The temperature
sensor inside the box is placed in the middle of the right side of the power supply with a distance of 1cm. The following
measurement results can be used as a reference to estimate the temperature rise inside the enclosure.
