Safetyinstructions:
General• Comply with the installation and safety instructions in the Operating
Instructions.
• Install the device according to the manufacturer's instructions andany other valid standards and regulations (e.g. EN/IEC 60079-14).
• Seal the cable entries with certified cable glands and or blanking
elements which have at least type of protection Ex ec or Ex tb suitablefor Group IIC and IIIC (degree of protection IP6X).
• The provided cable entries to option code glands are suitable ATEX/
IECEx Ex certified cable glands with a temperature 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 housing of the thermometer/sensor must be connected to the
local potential equalization or installed in a grounded metallic piping
or tank respectively.
• It cannot be taken for granted that when using compression fittings(e.g. TA50, TA60, TA70) with non metallic olives that there is asecure grounding when installing in a metal system. This means thatan additional safe connection to the local potential equalizationneeds to be used.

TRxx, TCxx, TEC420, TS111, TM211, TM41x, TPx100, TSx310, TM1xx• Observe the safety instructions for the used transmitters.
• The device should never be used for hybrid mixtures (gas, dust, air).
• When using of a plug-in connector (e.g. TURCK PA-connector) is tobe observed that the requirements for the respective category and theoperating temperature are followed.

Safetyinstructions: Dust
ignition
protection by
enclosure "t"• For ambient temperatures higher than +70 °C, use suitable heatresisting 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.

Safetyinstructions:
Specific
conditions of use• Sensors for thermometers without thermowell (e.g. TX62, TR24,
TX88) are to be mechanically protected by thermowell or equivalent
suitable for category 3 in compliance with EN/IEC 60079-0 and its
ultimate application.
• For assure that the temperature assembly has a degree of protectionof IP54 or IP6X depending on the ultimate application the user shallprovide a thermowell or equivalent component at the process side.
• Sensors of TM111/TM112 with a diameter smaller than 6 mm or ¼"
shall be protected by a thermowell.
• TM131, TM15x temperature sensors shall always be protected by athermowell.
• It shall be verified, taking into account the worst case process andambient temperatures,• that the temperature of the enclosure at the process connection
point does not exceed the ambient temperature range of theassembly.
• the temperature of the optionally used RBFF1NS union does notexceed the service temperature range of –50 to +150 °C forfollowing option:
TM131-abc...
TM151-abc...
c Thermometer Design:
M Nipple-union connection NPT½
N Nipple-union-nipple connection NPT½
• Install only head transmitters not exceeding a maximum power
dissipation of 2.2 W with a temperature input rating not exceeding
10 VDC and 1 mA.
• The thermometer must be installed and maintained so, that even in
the event of rare incidents, an ignition source due to impact orfriction between the enclosure and iron/steel is excluded.

For type of protection Ex nA: (for inserts/sensors only)
For use in the type of protection Ex nA, and for Zone 2 (EPL Gc)
application, the sensor/insert shall be installed completely inside an
additional enclosure, providing a degree of protection of not less than
IP54 according to IEC/EN 60079-0 and IEC/EN 60079-15. The
ambient temperature within the end use enclosure shall not exceed thelimits of the permissible ambient temperature range. Clearances,
creepage distances, and separations as defined in IEC/EN 60079-15
must be considered for the installation.
For type of protection Ex t: (for inserts/sensors only)
For use in the type of protection Ex tc, and for Zone 22 (EPL Dc)
application, the sensor/insert shall be installed completely inside an
additional enclosure, providing a degree of protection of not less than
IP54 in event of non-conductive dust or IP6X in event of conductive
dust according to IEC/EN 60079-0 and IEC/EN 60079-31.

LWARNING
Explosive atmosphere‣ In an explosive atmosphere, do not open the device when voltage is
supplied (ensure that the IP6x housing protection is maintained
during operation).
