SAVE THESE INSTRUCTIONS 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.
