Grounding the Cabinet
Note:
Follow Applicable Codes! The user is responsible
for conforming to all applicable, local, national, and
international codes. Failure to observe this
precaution could result in damage to, or
destruction of, the equipment.
Use the following steps to ground the cabinet:
1. Open the left-hand enclosure door of the drive. The
grounding stud is located just above and to the right of
the breaker.
2. Run a suitable earth ground (completed by field) to the
cabinet’s ground connection point. The grounding lug
is capable of accepting up to 2–600 MCM wire. For
AWG/MCM equivalents in mm2, refer to
Tighten the ground connections to 375 in·lb
(42.4 N·m).
WARNING
Hazardous Voltage/Improper Grounding!
Hazardous voltage due to improperly grounded
electrical components could result in death or serious
injury. The motor controller has a chassis ground that
must be connected to an earth ground.
