ABB ACQ80-04 Series User Manual

WARNING! WARNING!
Before using tools, make sure that the nut/screw is not cross-threaded.
Cross-threading can damage the drive and cause danger.
• Tighten the combi screw to a torque of 30 N·m (22 lbf·ft).
• Tighten the conductor(s) to 40 N·m (30 lbf·ft) for frame R8 or to 70 N·m (52 lbf·ft) for
frame R8.
11. Frames R8 only: If you install parallel cables, install the second grounding shelf for the
parallel power cables (11a). Repeat steps 6...11 (11b).
Frame R8:

Terminals L1, L2 and L3
• Remove the combi screw that attaches the connector to its terminal post, and
pull the connector off.
• Put the conductor under the connector pressure plate and pre-tighten the
conductor.
• Put the connector back onto the terminal post. Start the combi screw, and turn
it at least two rotations by hand.
WARNING! Before using tools, make sure that the nut/screw is not cross-
threading. Cross-threading will damage the drive and cause danger.

13. Reinstall the shroud on the power terminals.
14. Secure the cables outside the unit mechanically.
15. Ground the motor cable shield at the motor end. For minimum radio frequency
interference, ground the motor cable shield 360 degrees at the lead-through of
the motor terminal box.
