1.
Lift the service table all the way up until it is locked.
2.
Strip the mains and motor cables.
3. In an IP54 installation, make openings for the cables in the grommets on the bottom of the cabinet.
This instruction applies for IEC installations.
The grommets must be suited to the output diameter of the cable. The cable diameter is 25–65 mm (1–2.6 in).
4.
Lead the power cables through the grommet holders.
5. Peel the cable shield and attach the end to the PE busbar.
6. Use cable clamps to fix the cables.
