4.3. EMC Compliant Installation
4.3.1. Recommended Installation for EMC Compliance
Control cables
Twisted-Pair shielded
cables for analog
control and motor
feedback signals.
Cable shield exposed
and 360° clamped to
grounded metal plate or PE
bar. All other 360° bonding
methods are acceptable.
Motor cable
3-phase and PE shielded cable.
Maintain shield as far as
possible along the cable

The 500 – 600V drives are not intended for use in Europe and are designed without the internal filter built-in. External filters would be
required with these models in order to achieve compliance with any given EMC standards.
Compliance with longer motor cable lengths can be achieved if the drive is used with an external EMC filter.
See notes below relating to the compliance in the above table.
