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.
DC voltage supply
Internal The internal voltage is provided at terminal X3.3/20. It serves to supply the
controller inhibit (CINH).
External The external voltage supply of the function module is required if communication is
to be maintained during a failure of the standard device supply.
