)
Note!
In the case of an external voltage supply and for greater distances between the
control cabinets, always use a separate power supply unit (SELV/PELV) that is
safely separated in accordance with EN 61800−5−1 in each control cabinet.
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.
