Make sure that the installation is in accordance with national and local codes. Obey these
general guidelines:
• Use separate conduits for the input power, motor, brake resistor (optional), and control
cabling.
• Use separate conduit for each motor cabling.
The following figure illustrates the cable routing guidelines with an example drive.

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.
