This instruction contains important
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:

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.
