ABB ACS880-01 - Connection Procedure for Frames R4 to R5

￭ Connection procedure for frames R4 to R5
1. Fasten the cable conduits to the cable lead-through plate holes. Slide the cables
through the connectors.
2. Strip the cable ends and cut to suitable length (note the extra length of the grounding
conductors).
3. Ground the pair-cable shields to a grounding clamp below the control board. Leave
the other end of the shields unconnected or ground them indirectly via a
high-frequency capacitor with a few nanofarads, eg, 3.3 nF / 630 V.
4. Connect the conductors to the appropriate terminals of the control board.
5. Wire the optional modules if included in the delivery. For connecting the fieldbus
cables, see ACS880-01 quick installation guide for frames R4 and R5
(3AUA0000085966 [English]).
6. Reinstall the front covers.
