5.2.5 External voltage supply
The communication module can be supplied externally with voltage via separate supply cables at
the 2-pole plug connector X245.
External voltage supply of the communication module is necessary if the bus communication is to
be continued in the event of a failure of the supply of the standard device.
Access to parameters of a standard device disconnected from the mains is not possible.
