5.2.5 External voltage supply
The communication module can be externally supplied with voltage via separate supply cables at
the 2-pin plug connector X258.
The external voltage supply of the communication module is necessary if the power supply for the
basic device fails but communication via the fieldbus is to be maintained.
The parameters of a standard device separated from the mains cannot be accessed.
