Voltage supply
External voltage supply
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.
External voltage supply of the communication module is required if communication is to be
maintained even if the supply of the standard device fails.
If required, feed the communication module with a separate supply voltage via the
two−pole plug connector.
