Effective motor cable screens
The general rule for cable screen effectiveness is: the better and
tighter the screen, the lower the radiated emission level. The
following figure shows an example of an effective construction
(for example Ölflex-Servo-FD 780 CP, Lappkabel or MCCMK,
NK Cables).
Inner Insulator

Insulation Jacket

Braided metallic Screen
Clamp the cable shield into the gland plate at the drive end and
twist the cable screen wires together into a bundle not longer
than five times its width and connect it to the terminal marked
(at the bottom right-hand corner of the drive), if you are using
cable without a separate PE conductor.
