2.4.1 Connecting the power supply and the signal contact
lines

Supply voltage
The supply voltage can be connected redundantly. Both inputs are
uncoupled. There is no distributed load. With redundant supply, the power
supply unit with the higher output voltage supplies the device on its own.
The supply voltage is electrically isolated from the housing.

Remove the terminal connector from the device.

Connect the wires according to the pin assignment on the device with
the clamps.

Fasten the wires connected by tightening the terminal screws.

Signal contact (optional)

Connect the wires according to the pin assignment on the device with
the clamps.

Fasten the wires connected by tightening the terminal screws.
