Installation

Endress+Hauser

Type of protection flameproof• 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. EN/IEC 60079-14).
• The housing of the field transmitter must be connected to thepotential matching line.
• Only the approved wire entries as specified in paragraph 10.3 ofEN/IEC 60079-14, paragraph 16 of EN/IEC 60079-0, paragraph 13of EN/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 unused entry glands with approved sealing plugs that correspondto the type of protection.
• For operating the field transmitter housing at an ambient
temperature under –20 °C, appropriate cables, cable entries andsealing facilities permitted for this application must be used.
• For ambient temperatures higher than +70 °C, use suitable heatresisting cables or wires, cable entries and sealing facilities for Ta+5 K above surrounding.
• During operation, the cover must be screwed all the way in and thecover's safety catch must be fastened.

iTEMP TMT71, TMT72, TMT82, TMT84, TMT85, TMT86• The remote or integral mounted temperature sensor must comply
with the requirements according to EN/IEC 60079-1.
• Use for remote temperature sensors only approved sensors certified
for category 2G marked not less than II2G Ex d IIC T6…T4 Gb for use
in Zone 1 (EPL Gb).
• Use for integral temperature sensors only approved sensors certifiedfor category 1G or 2G marked not less than II1/2G Ex d IIC T6…T4Ga/Gb or II2G Ex d IIC T6…T4 Gb for use in Zone 0 (EPL Ga) resp.
Zone 1 (EPL Gb).
• The temperature class specified for the certified temperature sensor
shall be taken into account.
• The transmitter 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.
• The flameproof joints are not intended to be repaired.

LWARNING
Explosive atmosphere‣ Do not open the electrical connection of the power supply circuitunder voltage in an explosive atmosphere.
Dust ignition protection• 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. EN/IEC 60079-14).
• Seal the cable entries tight with certified cable glands (min. IP6X)
IP6X according to EN/IEC 60529.
• The provided cable glands according to option code are suitable
ATEX/IECEx Ex-certified cable glands with a temperature range of-20 °C...+95 °C.
• For operating the transmitter housing at an ambient temperature
under -20 °C, appropriate cables, cable entries and sealing facilities
permitted for this application must be used.
• The housing of the field transmitter must be connected to thepotential matching line.
• For ambient temperatures higher than +70 °C, use suitable heatresisting cables or wires, cable entries and sealing facilities for Ta+5 K above surrounding.
