Normal Mode

Normally, the utility supplies UPS power.

provide computer grade power to the loads. The UPS also "float-charges" the batteries and

displays the % UPS output load on the LOAD bar.

Battery Mode

If the UPS senses low voltage or a power outage, the battery instantly supplies UPS power.

In battery mode, the UPS sounds an alarm, turns OFF the AC indicator, and lights the

BATTERY indicator. In this mode, the CAPACITY bar displays battery power remaining

before depletion. Initially, the UPS sounds a 1 second tone every 4 seconds, but increases

to 4 tones every second when there is approximately 2 minutes of battery time remaining.

The UPS supplies internal battery power to a full load for 10 minutes before shutdown.

Increase this time by turning OFF non-critical equipment. Do not turn OFF UPS in battery

mode while supporting a critical load.

Battery Recharge

Upon return of utility power, the UPS automatically reverts to normal operation and

recharges the battery. Significant battery discharge causes the CAPACITY bar to flash 1,

2, or 3 left most segments. As the battery charges, the segments stop flashing one by one

until all light steadily, indicating full charge.
