66 Electrical installation
11. With frame size C or D, cut suitable slots on the edges of the connector covers to
accommodate the supply and motor cables. Install the covers again. (Tighten the
screws to 3 N·m [25 lbf·in]).
12. Secure the cables outside the unit mechanically.
13. Ground the other end of the supply cable shield or PE conductor(s) at the
distribution board. In case a mains choke and/or an EMC filter is installed, make
sure the PE conductor is continuous from the distribution board to the drive.
Grounding the motor cable shield at the motor end
For minimum radio frequency interference, ground the cable shield 360 degrees at
the lead-through of the motor terminal box
or ground the cable by twisting the shield so that the flattened shield is wider than 1/5
of its length.
