Figure 4-23 Shielding requirements of optional external braking resistor
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 as shown in Figure 4-24. 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
Alternatively, wiring may be passed through a ferrite ring, part no. 3225-1004.
