Information about mounting

The installation position can be selected as required.
To connect the device to the electrical system, use screw terminals. To connect it to the bus, use the
supplied bus connection terminal. The terminal assignment is located on the housing.
Once the bus and auxiliary voltages are connected, the device is ready for operation.
The maximum permissible current of a KNX line must not be exceeded.
During planning and installation ensure that the KNX line is correctly dimensioned.
The device has a maximum current consumption of <10 mA.
DANGER – Severe injuries due to touch voltage
Feedback from differing phase conductors can produce touch voltages and lead to severe injuries.
Operate the device only in a closed housing (distribution board).
Disconnect all phases before working on the electrical connection.
