MODES OF OPERATION
Normal Mode Operation
During normal operation, utility power provides energy to the UPS. The filters, the power fac-
tor correction circuit and the inverter process this power to provide computer-grade power to
connected loads. The UPS maintains the batteries in a fully charged state.
Battery Mode Operation
The UPS will enter Battery mode if there is a power surge, extreme power drop, or utility fail-
ure. The battery system supplies power through the DC to DC converter to the inverter to
generate power for the connected load.
!
CAUTION
Turning off the UPS while in battery mode will shut off output power.
