Note!
Always use a separate power supply unit in every control cabinet and safely
separate it according to EN 61800−5−1 ("SELV"/"PELV") in the case of external
voltage supply and larger distances between the control cabinets.
The communication module can be supplied with voltage externally via separate supply
cables at the 2−pole X232 plug connector.
The external voltage supply of the communication module is required if communication via
the fieldbus is to be continued in case the supply of the standard device fails.
