1.4 Compliance to UL Standards
1.4.1 UL Cautions
This section summarizes the items required for UL standard compliant inverter installation.
GENERAL:
WJ series C1 inverter is open type AC Inverter with three/single phase input and three phase
output. It is intended to be used in an enclosure. It is used to provide both an adjustable voltage
and adjustable frequency to the AC motor. The inverter automatically maintains the required
volts-Hz ratio allowing the capability through the motor speed range. It is multi-rated device,
and the ratings are selectable according to load types by operator with keypad operation.
