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 following gure provide a solid, high-frequency bonding between the
driven machine and the converter.
