WARNING
EQUIPMENT HAZARD
Rotating shafts and electrical equipment can be
hazardous. All electrical work must conform to national
and local electrical codes. It is strongly recommended
that installation, start up, and maintenance are
performed only by trained and qualified personnel.
Failure to follow these guidelines could result in death or
serious injury.
CAUTION
WIRING ISOLATION
Run input power, motor wiring, and control wiring in 3
separate metallic conduits, or use separated shielded
cable for high frequency noise isolation. Failure to isolate
power, motor, and control wiring could result in less
than optimum performance of the frequency converter
and associated equipment.
