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 and the conductors to a length of 7 to 8
mm, and bring them up to the end sleeves.
6. Connect the wires in the connector according to the connection diagram (Figure 4).
7. Close the cover (Figure 5).
8. Retighten the screw (Figure 6). This effects a strain relief on the lines.

9. Insert the power connector into the module, until the latch engages.
