Note: For frames R8 and R9:
• If you put only one conductor to the connector, ABB recommends that you put
it under the upper pressure plate.
• ABB does not recommend that you detach the connectors. If you do, detach
and reinstall the connector as follows.
L1, L2 and L3 connectors
a. Remove the combi screw that attaches the connector to its terminal post,
and pull the connector off.
b. Put the conductor under the connector pressure plate and pretighten the
conductor.
c. Put the connector back onto the terminal post. Start the combi screw, and
turn it at least two rotations by hand.
WARNING! Before you use tools, make sure that the nut/screw is not
cross-threading. Cross-threading will damage the drive and cause
danger.
d. Tighten the combi screw to a torque of 30 N·m.
e. Tighten the conductor(s) to 40 N·m for frame R8 or to 70 N·m for frame R9.
T1/U, T2/V and T3/W connectors
a. Remove the nut that attaches the connector to its busbar.
b. Put the conductor under the connector pressure plate and pretighten the
conductor.
c. Put the connector back to its busbar. Start the nut, and turn it at least two
rotations by hand.
WARNING! Before you use tools, make sure that the nut/screw is not
cross-threading. Cross-threading will damage the drive and cause danger.
d. Tighten the nut to a torque of 30 N·m.
e. Tighten the conductor(s) to 40 N·m for frame R8 or to 70 N·m for frame R9.
