This instruction contains important

SAVE THESE INSTRUCTIONS instructions for the G8000 Series 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.

The input and output of the UPS System 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:

Capacity	Rated Output	Breaker Rating	Capacity	Rated Output	Breaker Rating
			100kVA	480V/277Vac	480V-150A
125kVA	380V/220Vac	380V-250A	150kVA	480V/277Vac	480V-225A
180kVA	380V/220Vac	380V-350A	225kVA	480V/277Vac	480V-350A
250kVA	380V/220Vac	380V-500A	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:

Capacity	Rated Input	Breaker Rating	Capacity	Rated Input	Breaker Rating
			100kVA	480V/277Vac	480V-150A
125kVA	380V/220Vac	380V-250A	150kVA	480V/277Vac	480V-225A
180kVA	380V/220Vac	380V-350A	225kVA	480V/277Vac	480V-350A
250kVA	380V/220Vac	380V-500A	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 subje cted to the same temperature.

The nominal battery voltage for these models is 336Vdc for 125, 180 & 250kVA, and is 360Vdc for 100, 150, 225 & 300kVA. The nominal battery float voltage is 375Vdc for 125, 180 & 250kVA, and is 405Vdc for 100, 150, 225 & 300kVA.

Only a certified service representative with battery experience should perform service on batteries. Keep unauthorized people away from batteries.

Please refer to the battery manufacturer’s instruction when battery maintenance and/or replacement are scheduled.

CAUTION	Misuse of this equipment could result in personal injury and/or
	equipment damage.
	In no event will Toshiba Corporation be responsible or liable for either
