
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.
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.
Connection of the 2-pin plug connector (X200):
