DANGER
ELECTRIC SHOCK
There are live components behind the touch protections. Lack of touch protections can cause death or serious
injury.
l After power cabling, reinstall all touch protections at their original places.
1. Strip the mains and motor cables.
2. Make openings for the cables in the grommets at the top of the cabinet.
This 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).
3. Lead the power cables through the grommet holders.
4. Peel the cable shield and attach the end to the PE busbar.
5. Use cable clamps to fix the cables.
6. To make a 360° connection, expose the shield of the cables. Use a cable tie to attach the knitted metal mesh tube.

7. Connect the mains cables to the terminals L1, L2, and L3, and the motor cables to the terminals U, V, and W.
See the correct tightening torques in 6.1 Tightening Torques.
8. Connect the grounding conductors to the PE busbar.
