Control cable connection procedure

WARNING! Follow the safety instructions, page 14. Ignoring the instructions
can cause physical injury or death, or damage to the equipment.
1. Disconnect the drive from the power line. Lock the main disconnecting device and
ensure by measuring that there is no voltage.
2. Remove the front cover(s). See section
from page 94.
3. Cut adequate holes into the rubber grommets and slide the grommets onto the
cables. Slide the cables through the holes of the bottom plate and attach the
grommets to the holes.
4. Route the cables as shown on page 117.
5. Ground the outer shields of all control cables 360 degrees at a grounding clamp in
the cable entry box, see page 117. Tighten the clamp to 1.5 N·m (13 lbf·in). Keep
the shields continuous as close to the terminals of the control unit as possible.
Secure the cables mechanically at the clamps below the control unit. Frames R1
to R3: Ground also the pair-cable shields and grounding wires at the cable entry
box grounding clamp.
6. Frames R4 to R9: Ground the pair-cable shields and all grounding wires to the
clamp below the control unit, see page 117.
7. Connect the conductors to the appropriate terminals (see page
unit and tighten to 0.5 N·m (5 lbf·in).
8. For connecting the fieldbus cables, see appropriate quick installation guide:

ACS880-01 quick installation guide for frames R4 and R5
ACS880-01 quick installation guide for frames R6 to R9
Note:
• Leave the other ends of the control cable shields unconnected or ground them
indirectly via a high-frequency capacitor with a few nanofarads, eg, 3.3 nF / 630 V.
The shield can also be grounded directly at both ends if they are in the same
ground line with no significant voltage drop between the end points.
• Keep any signal wire pairs twisted as close to the terminals as possible. Twisting
the wire with its return wire reduces disturbances caused by inductive coupling.
