Prepare the power cables:
1. Strip the cables.
2. Twist the shield wires.
3. Bend the conductors to the terminals.
4. Cut the conductors to adequate length. Put the pedestal onto the lead-through plate and check the
length of the conductors. Remove the pedestal.
5. Press cable lugs in the conductors, or screw in connectors.
6. Connect the twisted shields of the cables to the PE terminal (frame size R7), or to the grounding
clamps or PE terminal (frame size R8).
Note: 360 degrees grounding is not needed at the cable entry. The short twisted shield provides, in
addition to the protective grounding, also sufficient disturbance suppression.
