Shield connections

The following guidelines should be followed to ensure suppression of radio-frequency emission and
good noise immunity. Use the grounding bracket and grounding clamp supplied with the drive to
terminate the shields at the drive.
Figure 4-9 Grounding of signal cable shields using the grounding bracket
Motor cable: Use a motor cable with an overall shield. Connect the shield of the motor cable to the
ground terminal of the motor frame using a link that is as short as possible and not exceeding 50 mm
(2 in) long. A full 360 ° termination of the shield to the terminal housing of the motor is beneficial.
Control cables: If the control wiring is to leave the enclosure, it must be shielded and the shield(s)
clamped to the drive using the grounding bracket. Remove the outer insulating cover of the cable to
ensure the shield(s) make contact with the bracket, but keep the shield(s) intact until as close as
possible to the terminals.
