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).

Insulation jacket

Braided metallic shield
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.
