10.6.5 Connecting a grounding set
1. Connect the enclosure ground clamp (10-10: 1)
to the ground ball stud of the cabinet’s ground-
ing frame.
2. Use the telescopic insulating pole to connect
the busbar ground clamps (10-10: 2) to the
ground ball studs of the busbars, and to tighten
each connection.
Connect the inner most busbar first (10-10: 3),
then the middle busbar (10-10: 4) and then the
outer busbar (10-10: 5).
The drive is now dead, and safe access is possible.
