WARNING
Proper Field Wiring and Grounding
Required!
Failure to follow code could result in death or serious
injury. All field wiring MUST be performed by qualified
personnel. Improperly installed and grounded field
wiring poses FIRE and ELECTROCUTION hazards. To
avoid these hazards, you MUST follow requirements for
field wiring installation and grounding as described in
NEC and your local/state electrical codes.
NOTICE
Use Copper Conductors Only!
Failure to use copper conductors could result in
equipment damage as unit terminals are not designed
to accept other types of conductors.
1. Run a suitable, unbroken, grounding conductor from
the drive cabinet's ground connection terminal to the
motor's ground terminal, and then on to earth ground.
