Is it necessary to terminate the grounding conductor directly to the grounding terminal?

For safe, dependable operation, ground the drive controller according to the National Electrical Code and all local codes. To ground the
drive controller:
- Connect a copper wire from the ground terminal on the drive controller (see Figures 11?18 on pages 34?41) to the power system ground conductor. Wire size is determined by the drive controller size and by national and local codes.
- Verify that the resistance to ground is 1 Ohm or less. Improper grounding causes intermittent and unreliable operation.
