Connecting the power cables
Connection diagram
Notes:
• Do not use an asymmetrically constructed motor cable.
• If there is a symmetrically constructed grounding conductor in the motor cable in
addition to the conductive shield, connect the grounding conductor to the
grounding terminal at the drive and motor ends.
• Route the motor cable, input power cable and control cables separately. For more
information, see section
on page
.
Grounding of the motor cable shield at the motor end
For minimum radio frequency interference:
• ground the cable by twisting the shield as
follows: flattened width > 1/5 · length
• or ground the cable shield 360 degrees at the
lead-through of the motor terminal box.

1.
Ground the other end of the PE conductor at the distribution board.
2.
Use a separate grounding cable if the conductivity of the cable shield is insufficient
(smaller than the conductivity of the phase conductor) and there is no symmetrically
constructed grounding conductor in the cable. See section

.
