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.
•
Each of the intrinsically safe circuits in the electronic
submodule are to be laid separately and should not be laid
together with the ground wires. Observe the regulations in
EN 60 079-14.
•
Sensors 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 assignments can be found in the
ET 200iSP Distributed I/O manual.
•
The safety data (maximum values) for the sensor must be
adjusted to the electronic submodule's corresponding
maximum values. The maximum values of the
sensor/actuator can be found in the associated ex
certificate. In accordance with EN 60 079-14, the following
are valid:
≤ U ≤ I

Assembly
•
Check that the electronic submodule is not damaged.
Only connect undamaged electronic submodules to the
terminal module.
•
The first time that an electronic submodule is inserted, the
coding elements on the terminal submodule will snap in
(self-coded and type-coded) which prevents the insertion
of the incorrect submodule. This mechanical coding may
not be changed.
