8.6 Connecting the system power/load current supply
Introduction
The power supplies/load current supplies power connectors are plugged in the delivery state
of the system. The modules and the associated power connectors are coded. There are two
parts to the coding element. One coding element is located in the module, and the other in
the power connector. The system power supplies/load current supplies use identical power
connectors for the voltage connection.
The coding element prevents the insertion of a power connector into a different type of
system power supply/load current supply.
Tools required

To connect the supply voltage, follow these steps:
1. Swing the front cover of the module up until the front cover latches.
2. Press down the unlocking button of the power cable connector (Figure 1). Remove the
power cable connector from the front of the module.
3. Loosen the screw on the front of the connector. This loosens the housing latch and the
cable relief. With a tightened screw the connector's cover can't be removed (Figure 2).
4. Pry off the connector cover using a suitable tool (Figure 3).

5. Strip the cable sheathing to a length of 35 mm. Strip the wires to a length of 7 to 8 mm.
Attach the end sleeves.
6. Connect the wires in the connector according to the connection diagram (Figure 4).
7. Close the cover (Figure 5).
