GENERAL:
Model 3G3RX2 series inverter is an open type AC Inverter with three phase input and three phase out-
put. 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 a multi-rated device and the ratings are
selectable according to load types by operator with key pad operation.
* For actual use, use within the temperature range indicated in the common specifications.
3G3RX2 series models Short circuit rating and overcurrent protection device
rating:
• 3G3RX2-A2

Integral:
Integral solid state short circuit protection does not provide branch circuit protection. Branch circuit
protection must be provided in accordance with the National Electrical Code and any additional local
codes.
Integral solid state short circuit protection does not provide branch circuit protection. Branch circuit
protection must be provided in accordance with the Canadian Electrical Code, part1" or the equiva-
lent. (For Canada)
