￭
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.
￭
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).
