1.3. SYSTEM DESCRIPTION

The UPS is designed to operate as a uninterruptible power supply in the following mode at 1980 watts output.:

A. Normal - In normal operation incoming AC power is fed to the input, conditioned and applied to the connected equipment. In this mode, power is also derived from utility power for the battery charger. In the event of a utility outage or severe abnormality (sag or swell), the UPS will support the connected load from battery power, until the battery is discharged or the utility returns; whichever occurs first.

B. Battery - Upon failure of utility / mains AC power, the critical AC load is supplied by the battery.

C. Recharge - Upon restoration of utility / mains AC power, after a utility / mains AC power outage, the input converter automatically restarts and resumes supplying power to the connected load and the battery charger to recharge the battery.

D. Automatic Restart - Upon restoration of utility / mains AC power the UPS automatically restarts and assumes supplying power to the critical load and the battery charger
