Conduit
Continuous motor cable shield/conduit or enclosure for equipment on the motor
cable
To minimize the emission level when safety switches, contactors, connection boxes
or similar equipment are installed on the motor cable between the drive and the
motor:
•
Install the equipment in a metal enclosure.
•
Use either a symmetrical shielded cable, or install the cabling in a metal conduit.
•
Make sure that there is a good and continuous galvanic connection in the
shield/conduit between drive and motor.
•
Connect the shield/conduit to the protective ground terminal of the drive and
the motor.
