Wiring the TM-IM/EM, TM-EM/EM terminal submodule
• When laying the cable and connecting the submodule,
observe the regulations in EN 60 079-14 plus any
applicable national regulations.
• In wiring the submodule, you must strictly separate the
intrinsically safe lines from the non-intrinsically safe. They
must be laid in separate cable ducts.
• Actuators from Zone 0, Zone 1, Zone 2 as well as Zone 20,
Zone 21, Zone 22 and the secured area may be connected
to the terminal submodule. The electronic submodule's
terminal assignment can be found in the Distributed I/O
ET 200iSP operating instructions.
• The safety data (maximum values) for the
sensors/actuators must be adjusted to the electronic
submodule's corresponding maximum values. The
maximum values of the sensors/actuators can be found in
the associated ex certificates. In accordance with
EN 60 079-14, the following applies:
≤ U ≤ I

Assembly
• Check the electronic submodule for damage. Only connect
undamaged electronic submodules to the terminal module.
• The first time that an electronic submodule is inserted, the
coding element on the terminal submodule will snap in,
which prevents the insertion of an incorrect submodule.
This mechanical coding may not be changed.
• In Zone 1 and Zone 2, the electronic submodule may be
inserted and removed during operation. The enclosure
(Ex e / IP 54) in which the ET 200iSP is found may only be
opened briefly for this purpose (see the Distributed I/O
ET 200iSP operating instructions).
