Mounting and installation
5.1
Information about mounting
The mounting position for the device can be selected as required.
The electrical connection is made via screw terminals. The connection to the bus is made via the supplied
bus connecting terminal. The terminal designation is located on the housing.
After connecting the supply voltage, the unit is ready for operation.
DANGER – Severe injuries due to touch voltage
Electric feedback from different phase conductors can cause contact voltages and lead to serious
injuries.
Operate the device only in a closed housing (distribution board).
Disconnect all phases before working on the electrical connection.
5.2
Mounting on DIN rail
The device is fitted and removed without auxiliary tools.
Make sure the device is accessible for operation, testing, visual inspection, maintenance and repair.
Fig. 4: Mounting on DIN rail
1.
Place the DIN rail holder on the upper edge of the DIN rail and push down.
2.
Push the lower part of the device toward the DIN rail until the DIN rail holder engages.
The device is now mounted on the DIN rail.
Relieve the pressure on the top of the housing.
5.3
Connecting the floating changeover contact
To monitor fault messages, either the normally closed contact or the normally open contact of the floating
changeover contact or both can be used. In doing so, you can, for example, use an LED to indicate
whether the line is working properly or whether there is a malfunction.
