Effective motor cable shields
The general rule for cable shield effectiveness is: the better and
tighter the shield, the lower the radiated emission level. The
figure below shows an example of an effective construction (for
example Ölflex-Servo-FD 780 CP, Lapp Kabel or MCCMK,
Draka NK Cables).
Clamp the cable shield into the gland plate at the drive end, twist
the cable shield wires together into a bundle (pigtail) 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
a cable without a separate PE conductor.
