Connection procedure (frame R8i and multiples)

￭
The cable entry details, and cable connection details are shown in section Terminal and
lead-through data for the input power cable in the technical data.
WARNING!
Obey the safety instructions of the drive. If you ignore them, injury or death,
or damage to the equipment can occur. If you are not a qualified electrical
professional, do not do installation or maintenance work.
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.
Obey the instructions in section
2. Open the door of the incoming cubicle.
3. Remove the shrouding covering the input terminals.
4. Peel off the outer insulation of the cables above the lead-through plate for 360°
high-frequency grounding.
5. Prepare the ends of the conductors.
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 in the technical data.
11. 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.
12. Reinstall the shrouding removed earlier.
13. Close the door.
