Rockwell Automation GV3000/SE AC Drive Ver. 6.06 Hdwe Ref., Installation, and Troubleshooting Manual - Manual (Page 119)

Compliance with Electromagnetic Compatibility Standards C-11
C.4.2 Motor Leads
The motor leads must be run in continuous, rigid, conductive conduit,
continuously-screened armored cable, or equivalent. Note that the use of flexible
metal conduit, open wire, or wire in trays is not acceptable. Many flexible metal conduit
products have not been designed for RF containment and are not adequate to
maintain compliance.
All motor leads should have the same cross-sectional area. The maximum allowable
motor lead length from the drive to the motor is 250’ (76m).
A ground (earth) lead, equivalent in size to the motor leads, must be run with the
motor leads from the motor to the drive. Terminate this lead in the drive at the ground
terminal.
Proper glands must be used to terminate the motor conduit/cable. The gland must
secure the cable screen to the conductive surfaces of the drive and motor. A full 360 °
screen termination is preferred.
Follow all instructions supplied with the motor.
C.4.3 Connecting AC Input Power to the AC Mains Filter
Connect AC input power to the filter by first removing the filter’s cover and then
connecting the AC input power leads to the terminals at the top of the filter. See figure
C.1. The AC input power leads should have lugs attached. The filter-GV3000/SE
cabinet has a conduit opening to secure the AC input power conduit.
