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).
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.
