Using shielded motor cables
A shielded cable must be used to connect the drive to motor. Ground the shield of the motor cable as close to the U, V, W terminals as possible. The
shield must be connected to the enclosure backplate by a good high-frequency connection, for example by direct clamping using a “U” clamp or
similar. Multiple zip-ties embracing and pressing the motor cable screen to the Cable Management Bracket accessory is an acceptable alternative.
The shield of the motor cable must be connected to the ground terminal of the motor frame using a link that is as short as possible, not exceeding 50
mm (2 in) in length. A full 360° termination of the shield to the motor terminal housing (if metal) is beneficial.
