• Remove the nut that attaches the connector to its busbar.
• Put the conductor under the connector pressure plate and pre-tighten the
conductor.

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.
• Tighten the nut 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 R9.
Terminals L1, L2 and L3
• Remove the combi screw that attaches the connector to its terminal post, and
