Power supply 160 mA, 320 mA, 640 mA, 1280 mA with integrated choke
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 connec-
tion 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 com-
munication.
If required, an identical power supply can be connected in parallel for the device variants
160, 320 and 640 mA.
Connecting the diagnostic analyser
The power supply signals mains failure, overvoltage, overload and short circuit using a poten-
tial-free contact (9). A monitoring device can detect the switching status and forward it for dia-
gnostic purposes.
