Cable routing and shielding
● Rout all inverter power cables (line supply cables, cables between the braking chopper
● Rout the cables from the line supply to the line filter separately away from the following
● Signal and data cables as well as filtered line supply cables may only cross non-filtered
● Keep all cables as short as possible.
● Rout signal and data cables and the associated equipotential bonding always in parallel
● Use shielded motor cables.
● Route the shielded motor cable separately away from the cables to the motor
● Shield signal and data cables.
● Connect shields at both ends to the grounded enclosures through a good electrical
● Connect cable shields as close as possible to where the cable enters the cabinet.
● Use EMC shield bars for power cables.
● Do not interrupt the cable shields by intermediate terminals.
● Use appropriate EMC clamps for the cable shields.

and the associated braking resistance as well as the motor cables) separately from signal
and data cables. Keep the minimum clearance to 25 cm. If the cables can not be
separated use metal partitions with a good connection to the mounting plate.

Use the shield support elements provided in the converter for signal and data cables.
The EMC clamps connect the cable shield to the EMC shield bar or the shield support
element through a large conductive area.
