Connecting
1 - Supply voltage
2 - Signal contact
For every supply voltage to be connected, perform the following steps:
 Verify the required conditions for connecting the voltage supply.
See “Supply voltage” on page 9.
 Remove the terminal connector from the device.
 Connect the protective conductor with the clamp.
 Connect the wires according to the pin assignment on the device with the
clamps.
 Mount the terminal block on the device using screws.
2.3.2 Wiring the signal contact
Relevant for North America:
The torque for tightening the terminal block for the signal contact on the
