Figure 4-6 Grounding bracket at the top of the drive
Figure 4-7 Grounding bracket at the bottom of the drive
Grounding bracket and drive to be directly connected to a grounded
backplate.
1. The distance for EMC (shown in Figure 4-7 above) from the drive is as
follows:
200 V drive - Allowance up to 65 mm (2.56 in)
400 V drive - Allowance up to 100 mm (3.94 in)
The grounding bracket can remain mounted when the drive is removed.
as follows.
