Power Supply P640 KNX, Power Supply P1280 KNX
Connecting the device to mains voltage and bus
■
Connect the mains voltage to the terminals L and N (1).
Connect the protective conductor PE to the terminal Ʈ.
■
Connect the KNX bus line to output Bus (6).
■
■
Install the cover to protect the bus connection against hazardous voltages in
the connection area.
The total load of the outputs can be subdivided as desired. Do not exceed the
total rated current.
Do not connect any other products to the bus output. This might influence the
bus communication.
If required, an identical voltage supply can be connected in parallel for the
device variant 640 mA.
