3. Connect the motor cable as follows:
If the power cable is temporarily removed from the grounding shelf, connect the
motor and input power cables except the 360 degree grounding, and then reinstall
the grounding shelf.
• Ground the shield 360 degrees by tightening the clamp of the power cable
grounding shelf onto the stripped part of the cable (4a).
• Connect the twisted shield of the cable to the grounding terminal (4b).
• Connect the phase conductors of the cable to the T1/U, T2/V and T3/W terminals.
• Tighten the screws to the torque given below:
Notes
• The screws are of different length. Install them at the correct locations.
• After reinstalling the grounding shelf, you can make the 360 degree grounding for
the cables.

4. Prepare the ends of the cable as illustrated in the figure.
Note: The bare shield will be grounded 360 degrees. Mark the pigtail made from the
shield as a PE conductor with yellow-and-green color.
