Additional measures
Finely stranded, braided copper cables have to be routed in parallel with the cable shields in
the following cases:
● Old installations with already existing unscreened cables
● Cables with poor high-frequency properties
● Installations with bad grounding systems
The connections in the figure below provide a solid, high-frequency bonding between the
motor housing, the motor terminal box, the gearbox, the driven machine and the EMC
busbar.
