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 instal-
lation, start up, and maintenance be 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 three
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 frequency converter and associated equipment
performance.
