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
figure below shows an example of an effective construction (for
example Ölflex-Servo-FD 780 CP, Lappkabel or MCCMK, NK
Cables).
Insulation jacket
Braided metallic screen
Clamp the cable shield into the gland plate at the drive end, twist
the cable screen wires together into a bundle not longer than
five times its width and connect it to the terminal marked
the bottom right-hand corner of the drive) if you are using a
cable without a separate PE conductor.
