the instructions can cause physical injury or death, or damage to the equipment.
1. Open the door of the incoming cubicle. Unlock the handle, release it from the holder
and turn upwards to release the door locking mechanism.
2. Remove the shroud that protects the grid cable connection busbars and cable entries.
3. When shielded cable is used:
Lead the cables into the inside of the cubicle through the IP sealing glands. Ground a
shielded cable 360° at cabinet PE busbar lead-through with an EMC cable gland (to
be supplied by the customer).
Connect the cables as follows:
•
Twist the cable shields into bundles and connect to cabinet PE (ground) busbar.
Connect any separate ground conductors or cables to cabinet PE (ground)
busbar.
•
Connect the phase conductors to terminals L1, L2 and L3. Tighten the phase
conductors and PE to 70 N·m (50 lbf·ft) torque.
When single-core cables without metal shield are used:
•
Lead the cables into the inside of the cubicle through the IP sealing glands.
•
Connect the phase conductors to terminals L1, L2 and L3, and the PE conductors
to the PE terminal. Tighten the phase and PE conductors to 70 N·m (50 lbf·ft)
torque.
4. Provide support for the cables whenever necessary.
5. Refit all shrouds removed earlier and close the door.
