FIELD-MOUNT TEMPERATURE TRANSMITTER | CI/TTF300-EN REV. H
… 2 Use in potentially explosive atmospheres in accordance with ATEX and IECEx
… Installation instructions
The transmitter must be connected using suitable cable and
cable entries or pipeline systems that satisfy the requirements
of EN 60079-1 and for which a separate examination certificate
exists. If the transmitter is connected to pipeline systems, the
relevant sealing device must be affixed directly to the housing.
Cable entries (PG glands) and sealing plugs of simple design
must not be used.
Close unused cable entry in accordance with EN 60079.-1.
The connection lead must be routed securely and in such a way
as to ensure adequate protection against damage.
If the temperature on the entry parts is over 70° C, connection
leads with sufficient temperature resistance must be used.
The transmitter must be integrated into the local potential
equalization of the potentially explosive area.
Commissioning
The commissioning and parameterization of the device may also
be carried out in potentially explosive atmospheres using a
handheld terminal that has been approved accordingly under
consideration of an intrinsic safety installation check.
Alternatively, an Ex modem can be connected to the circuit
outside the potentially explosive atmosphere.
