Figure 4-19 Shielding requirements of optional external braking resistor
Enclosure
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 4-20. Remove the outer insulating cover of the
cable to ensure the shield(s) make direct 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
number 3225-1004.
