Options
11.7 Monitoring functions
This option only includes monitoring the armature circuit, the fault current monitoring for the
auxiliary circuit or circuits must be realized on the plant side.
Note
For protection using a differential current monitor for shutdown, the protective conductor or
PEN conductor of the cables for the cabinet supply and motor armature circuit are
dimensioned according to DIN VDE 0100, Part 540. Line conductor cross-section according
to DIN VDE 0160. As a consequence, generally the cable cross-section can be reduced.

24 V DC or 230 V AC circuits can be connected at the terminals of terminal strip -X2. There
is safe electrical isolation to other circuits. For example, it is possible to connect a PLC. All
terminals of the option must be operated with the same
voltage level.
Diagnostics
For a description of messages output during operation and in the event of faults (meaning of
LEDs at = D3-F15), refer to the "Additional operating instructions" section of this
documentation package.
Cable routing
The cables are routed into the cabinet corresponding to the following diagrams.
