(Standard to comply with: UL508C, CSA C22.2 No14-5)
Warning Markings
GENERAL:
These devices are open type and/or Enclosed Type 1 (when employing accessory Type 1 Chassis Kit) AC Inverters
with three phase input and three phase output. They are intended to be used in an enclosure. They are used to
provide both an adjustable voltage and adjustable frequency to the ac motor. The inverter automatically maintains
the required volts-Hz ration allowing the capability through the motor speed range.
"Use 60/75C CU wire only" or equivalent.
