Cable shields
• Use shielded cables with finely stranded braided shields. Foil shields are not suitable since
they are much less effective.
• Connect shields to the grounded housings at both ends with excellent electrical conductivity
and a large contact area.
• Bond the cable shields to the plug connectors of the Converter.
• Don't interrupt cable shields by intermediate terminals.
• In the case of both signal and data cables, the cable shields should be connected by means
of suitable EMC glands. The cables must connect the shields to the shield bonding options for
cables and the unit housing respectively with excellent electrical conductivity and a large
contact area.
• Use only metallic or metallized connector housings for shielded data cables (for example,
PROFIBUS cables).

Equipotential bonding
Equipotential bonding within the drive system has to be established by connecting all electrical
and mechanical drive components (transformer, motor and driven machine) to the grounding
system. These connections are established by means of standard heavy-power PE cables, which
do not need to have any special high-frequency properties. In addition to these connections, the
converter (as the source of the high-frequency interference) and all other components in each
drive system (motor and driven machine) must be interconnected with respect to a high-
frequency point of view. For this purpose cables with good high-frequency properties must be
used.
