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.
•
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 assignment can be found in the ET 200iSP
Distributed I/O manual.
•
The safety data (maximum values) for the sensor/actuator
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
U ; I
0 i 0
Assembly
•
Check 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
which prevents the insertion of the incorrect submodule.
This mechanical coding may not be changed.
•
In Zone 1 and Zone 2, the electronic submodules 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 ET 200iSP
manual).
