Local potential equalization
A0039716-EN

Safety Instructions: General• Install the device according to the manufacturer's instructions and any other valid standards andregulations.
• Seal the cable entries with certified cable glands and or blanking elements which have at least typeof protection Ex ec or Ex tb suitable for Group IIC and IIIC (degree of protection IP6X).
• The provided cable entries to option code glands are suitable NEPSI certified cable glands with atemperature range of –20 to +95 °C.
• For operating the thermometer at an ambient temperature under –20 °C and above +95 °C,
appropriate cables, cable entries and sealing facilities permitted for this application must be used.
• The sensor/housing of the thermometer must be connected to the local potential equalization orinstalled in a grounded metallic piping or tank respectively.
• It cannot be taken for granted that when using compression fittings (e.g. TA50, TA60, TA70) withnon metallic olives that there is a secure grounding when installing in a metal system. This meansthat an additional safe connection to the local potential equalization needs to be used.
• Observe the safety instructions for the used transmitters.
• The device should never be used for hybrid mixtures (gas, dust, air).
• Sensors for thermometers without thermowell (e.g. Tx62, TR24, Tx88, TM111) are to bemechanically protected by thermowell suitable for category 3 in compliance with GB3836.1:2010
and its ultimate application.
• When using of a plug-in connector (e.g. PA-connector by Weidmüller) is to be observed that therequirements for the respective category and the operating temperature are followed.
• Staff must meet the following conditions for mounting, electrical installation, commissioning andmaintenance of the device:• Be suitably qualified for their role and the tasks they perform• Be trained in explosion protection• Be familiar with national regulations

XA02111T• For cable entries, appropriate cable glands or blind plugs for unused holes shall be used which areseparated certified; after installation, the product should be at least IP54 according to GB/T4208-2017.
• The used cable glands, blind plugs and cables should be suitable for the working condition for theapplication.
• Any maintenance shall be done only when the warning "Keep tight when the circuits are alive" isobeyed or the area known to be non hazardous.
• The user shall not change the configuration in order to maintain/ensure the explosion protection
performance of the equipment. Any change may impair safety.
• For installation, use and maintenance of this product, the end user shall observe the instruction
manual and the following standards:• GB 3836.13-2013 "Explosive atmospheres - Part 13: Equipment repair, overhaul andreclamation".
• GB/T 3836.15-2017 "Explosive atmospheres - Part 15: Electrical installations design, selectionand erection".
• GB/T 3836.16-2017 "Explosive atmospheres - Part 16: Electrical installations inspection andmaintenance".
• GB 50257-2014 "Code for construction and acceptance of electric device for explosion
atmospheres and fire hazard electrical equipment installation engineering".

LWARNING
Explosive atmosphere‣ In an explosive atmosphere, do not open the device when voltage is supplied (ensure that at least
IP54 is maintained during operation).
Safety instructions: Protection by type of protection "n"• Install the sensor in thermometer/terminal head enclosure suitable for Group II in compliance withenclosure requirements to GB3836.1:2010.
• When installing the device in an approved housing for category 3, note that the housing ingress
protection classification IP54 to IEC 60529 is upheld.
Safety instructions: Dust ignition protection by enclosure "t"• Sensors for thermometers without thermowell (e.g. TM111) are to be mechanically protected bythermowell providing a degree of protection of at least IP6X and in compliance with the enclosure
requirements to GB3836.1:2010.
• In the event of conductive dust, a housing that maintains a degree of protection of at least IP6x as
per EN/IEC 60529 must be used.
• In the event of non-conductive dust, a housing that maintains a degree of protection of at least
IP54 as per EN/IEC 60529 must be used.
• For ambient temperatures higher than 70 °C, use suitable heat-resisting cables or wires, cable
entries and sealing facilities for Ta +5 K above surrounding.
• Clean the housing regularly to avoid a layer of dust accumulating on the housing.
Safety instructions: Specific conditions of use• The maximum specified ambient temperature Ta at terminal head or field enclosure may not beexceeded.
• Install only head transmitters not exceeding a maximum power dissipation of 2.2 W with atemperature input rating not exceeding 10 VDC and 1 mA.
• The thermometer must be installed so, that even in the event of rare incidents, an ignition source
due to impact or friction between the terminal head and iron/steel is excluded.
• The suffix "X" placed after the certificate number indicates that this product is subject to special
conditions for safe use, that is:
The cable sensors TST310 and TSC310 should be properly protected for the free end of the cable,and electrostatic charges on the cable shall be avoided.
• From the safety point of view, the circuit of versions of the following temperature sensors andinserts hall be considered to connected to ground (for details, the instruction manual, provided
with the equipment, shall be observed):• Type TS111, TS211 with diameter 3 mm, single or dual
• Type TS111, TS211 with diameter 6 mm dual.
• The insert TS111, TS211 shall be provided with a mounting head comply with GB 3836.1-2010
and GB 3836.8-2014 including the cable entry device to ensure a degree of protection of at least
IP54 according to GB/T 4208-2017 when in use.
• Product with type of protection nA must guarantee that the rated voltage Un is not exceeded bymore than 40 % in the event of temporary faults.
