This instruction contains important
instructions for G8000U Series 100,
150, 225 and 300kVA that should be followed during the installation, operation, and maintenance of the
UPS systems. Please refer to the battery manufacturer’s instructions for details on operating and
maintaining the batteries for each system.
UPS System’s input and output are NOT equipped with an over-current protection device, or an output
disconnection at the AC output. Therefore, a circuit breaker should be provided by the user between the
UPS output and the critical load input. The minimum device ratings should be as follows:
Model
Rated Output Breaker Rating Model Rated Output Breaker Rating
100kVA 480V/277Vac 480V-150A 225kVA 480V/277Vac 480V-350A
150kVA 480V/277Vac 480V-225A 300kVA 480V/277Vac 480V-450A
Circuit breakers should be provided by the user between AC input (or Bypass input) and power sources.
The minimum device ratings should be as follows:
Model Rated Input Breaker Rating Model Rated Input Breaker Rating
100kVA 480V/277Vac 480V-150A 225kVA 480V/277Vac 480V-350A
150kVA 480V/277Vac 480V-225A 300kVA 480V/277Vac 480V-450A
The maximum ambient temperatures in which the UPS should be operated is 40°C (104°F) or 32°C (90°F)
maximum if the battery system is to be subjected to the same temperature.
The nominal battery voltage for these models is 360Vdc. The nominal battery float voltage is 405Vdc.
Only a certified service representative with battery experience should perform service on batteries. Keep
