Endress+Hauser• Comply with the installation and safety instructions in the OperatingInstructions.
• Install the device according to the manufacturer's instructions andany other valid standards and regulations (e.g. GOST 30852.13 (IEC60079-14)).
• The housing of the thermometer must be connected to the potential
matching line.

XA02695T

iTHERM TM111, iTHERM TM131• Only the approved wire entries as specified in paragraph 10 of GOST
30852.13 (IEC 60079-14), paragraph 16 of GOST 31610.0 (IEC60079-0), paragraph 13 of GOST IEC 60079-1 (IEC 60079-1) must
be used.
• For connection through a conduit entry approved for this purpose theassociated sealing facility shall be mounted directly to the housing.
• Seal the cable entries with certified cable glands and or blanking
elements which have at least type of protection Ex db and Ex tb
suitable for Group IIC and IIIC (degree of protection IP6X).
• The maximum specified ambient temperature Ta at terminal head
not be exceeded.
• For operating the thermometer housing at an ambient temperature
under –20 °C appropriate cables and cable entries permitted for thisapplication must be used.
• For ambient temperatures higher than +70 °C use suitable heatresisting cables or wires, cable entries and sealing facilities which canbe applied for temperatures +5 K above ambient temperature.
• During operation, the cover must be screwed all the way in and thecover's safety catch must be fastened.
• The thermometer must be installed so, that even in the event of rareincidents, an ignition source due to impact or friction between theenclosure and iron/steel is excluded.

LWARNING
Explosive atmosphere‣ Do not open the electrical connection of the power supply circuitunder voltage in an explosive atmosphere.

6• 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. GOST 30852.13 (IEC60079-14)).
• Seal the cable entries tight with certified cable which have at least
type of protection Ex tb suitable for Group IIIC (degree of protection
IP6X).
• The housing of the thermometer must be connected to the potential
matching line.
• For ambient temperatures higher than +70 °C use suitable heatresisting cables or wires, cable entries and sealing facilities which canbe applied for temperatures +5 K above ambient temperature.

supplied (ensure that the IP6X housing protection is maintained
during operation).
Safetyinstructions:
Partition wall

• The provided thermowells are out of materials AISI316/W.1.4401,
AISI316L/W.1.4404, AISI 316Ti/1.4571, Hastelloy® C-276, Alloy

• Use only thermowells out of materials complying with IEC/EN
60079-0 chapter 8.3 (e.g. AISI316/W.1.4401, AISI316L/W.1.4404,
AISI 316Ti/1.4571…).

Safetyinstructions:
Specific
conditions of use• The flameproof joints are not intended to be repaired.
• Sensors of TM111 with a diameter smaller than 6 mm shall beprotected by a thermowell.
• Following sensor options shall be protected by a thermowell:

iTHERM TM111, iTHERM TM131• Install only head transmitters not exceeding a maximum power
dissipation of 2.2Wwith a temperature input rating not exceeding
10 VDC and 1 mA.
• For assure that the temperature assembly has a degree of protectionof IP6X the user shall provide a thermowell or equivalent component
at the process side.
