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.

Separate control cable ducts

￭
Put 24 V DC and 230 V AC (120 V AC) control cables in separate ducts, unless the 24 V DC
cable is insulated for 230 V AC (120 V AC) or insulated with an insulation sleeving for
230 V AC (120 V AC).
