External voltage supply
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.
The external voltage supply of the communication module is required if communication
via the bus system is to continue in the event of a power supply failure of the standard
device.
ƒ The external voltage supply of the communication module is required if
communication is to continue when the power supply of the standard device fails.
ƒ Access to parameters of a standard device disconnected from the mains is not
possible.
ƒ The external voltage supply is effected via the 2−pole plug connector.
Assignment of the 2−pole plug connector (X200)
