Additional measures
Finely stranded, braided copper cables have to be routed in parallel with the cable shields in
the following cases:
● Old installations with existing unscreened cables
● Cables with poor high-frequency properties of the shield
● Installations with bad grounding systems
Connections shown in the following diagram offer a durable, high-frequency equipotential
bonding between the motor enclosure, the motor terminal box, the driven load and the EMC
rail/busbar.
