Prepare the power cables:
•
Remove the rubber grommets from the cable entry.
•
Cut a sufficient hole in the rubber grommet. Slide the grommet onto the cable (a).
•
Prepare the ends of the input power cable and motor cable as illustrated in the figure (b).
•
Slide the cables through the holes in the cable entry and attach the grommets to the holes.
•
If you use aluminum cables, apply grease to the stripped conductors before you connect them to the drive.

Connect the power cables. For the tightening torques, refer to
•
Connect the phase conductors of the motor cable to terminals T1/U, T2/V and T3/W. Connect the twisted shield of
the cable to the grounding terminal. (a)
•
Connect the input power cable to terminals L1, L2 and L3. Connect the twisted shield of the cable and the additional
PE conductor to the grounding terminal. (b)
•
Frames R8...R9: If you use only one conductor, ABB recommends that you put it under the upper pressure plate. If
you use parallel power cables, put the first conductor under the lower pressure plate and the second under the upper
pressure plate.
•
Frames R8...R9: If you use parallel power cables, install the second grounding shelf for the parallel power cables.
•
Tighten the clamps of the power cable grounding shelf onto the stripped part of the cables (c). Torque the clamps to
1.2 N·m (10.6 lbf·in).
•
If used, connect the brake resistor or brake chopper cables. In frames R1...R2, you must install the grounding shelf
before you can connect the brake cables (refer to the next step).
•
Frames R6...R9: After you connect the power cables, install the shroud on the terminals (d).
