In wiring the submodule, you must strictly separate the
intrinsically safe lines from the non-intrinsically safe.
Intrinsically safe and non-intrinsically safe lines may not be
laid together in a single cable duct.
Connect the AC 120/230V power supply (terminal L1/N) to
the TM-PS-A UC/TM-PS-B UC terminal module. You must
connect the potential equalization wire (in accord with
EN 60 079-14) to the terminal PA.
The comprehensive terminal assignment can be found in
the ET 200iSP Distributed I/O operating instructions.
Danger
Zone 1 and safety zone: the separation or termination of
supply voltage wires of the PS AC120/230V power supply
on the TM-PS-A US/TM-PS-B UC terminal submodules
may only be carried out when the supply voltage has been
switched off in zone 1 / 2 and the safety zone.
Assembly
In Zone 1 and Zone 2, the power supply 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 ET200iSP
operating instructions).
Commissioning
The relevant national regulations must be observed when
commissioning the system.
