Fuses or other protection means for the short-circuit protection of the cable.

Grounding of the cable shield at the cable entry (360 degrees grounding).
Additional information:
• See the technical data for the dimensions of the cable entries, and the dimensions and tightening torques
of the terminals.
• If the conductivity of the shields does not meet the requirement for the PE conductor, use a separate PE
conductor in addition.
• See ACS880 multidrive cabinets and modules electrical planning instructions (3AUA0000102324 [English])
for the cable selection instructions.

Connection procedure – bottom cable entry
See the technical data for the dimensions of the cable entries, and the dimensions and
tightening torques of the terminals.
WARNING!
Apply grease to stripped aluminum conductors before attaching them to non-coated
aluminum cable lugs. Obey the grease manufacturer's instructions.
Aluminum-aluminum contact can cause oxidation in the contact surfaces.
1. Disconnect the drive from the AC power line and make sure it is safe to start the work.
See section
Electrical safety precautions (page
2. Open the door of the incoming cubicle.
3. Remove the shrouding covering the input terminals.
4. Peel off 3 to 5 cm of the outer insulation of the cables above the lead-through plate for
360° high-frequency grounding.
5. Prepare the ends of the cables.
6. Remove the rubber grommet from the cable entry plate for the cable to be connected.
Cut adequate hole into the rubber grommet. Slide the grommet onto the cable. Slide
the cable through the cable entry and attach the grommets to the holes.
7. Fasten the conductive sleeve of the cable entry to the cable shield with cable ties.
8. Tie up the unused conductive sleeves with cable ties.
9. Connect the twisted shield of the cable to the PE busbar of the cabinet. Tighten the
screw to the torque given in the technical data.
10. Connect the phase conductors of the input cable to the L1, L2 and L3 terminals. Tighten
the screws to the torque given in the technical data.
