Connection Procedure (Frame R8I And Multiples) - ABB ACS880-207 Hardware Manual

Connection procedure (frame R8i and multiples)


The cable lead-through details, and cable connection details are shown in chapter
Terminal and lead-through data for the input power
WARNING! Only qualified electricians are allowed to do this work. Read the
complete safety instructions of the drive. Ignoring the instructions can cause
physical injury or death, or damage to the equipment.
WARNING! With aluminum cables, apply grease to stripped conductors before
attaching them to non-coated aluminum cable lugs. Obey the grease
manufacturer's instructions. Aluminum-aluminum contact can cause oxidation of
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
2. Open the door of the incoming cubicle.
3. Remove the shrouding covering the input terminals.
4. Peel off 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 grommets from the lead-through plate for the cables to be
connected. Cut adequate holes into the rubber grommets. Slide the grommets onto
the cables. Slide the cables through the lead-throughs with the conductive sleeves
and attach the grommets to the holes.
7. Fasten the conductive sleeves to the cable shields with cable ties.
8. Seal the slot between the cable and mineral wool sheet (if used) with sealing
compound (eg, CSD-F, ABB brand name DXXT-11, code 35080082).
9. Tie up the unused conductive sleeves with cable ties.
10. Connect the twisted shields of the cables to the PE busbar of the cabinet. Tighten the
screws to the torque given under
11. Connect the phase conductors of the input cable to the L1, L2 and L3 terminals.
Tighten the screws to the torque given under
12. Reinstall the shrouding removed earlier.
13. Close the door.
