OPERATION
NORMAL MODE OPERATION
During normal operation, mains power provides energy to the UPS. The filters and the power conditioning circuit process this power to provide computer grade power to connected loads. The UPS maintains the batteries in a fully charged state.
The front panel displays the percentage of load on the UPS output. The figure below indicates approximately
BATTERY MODE OPERATION
Battery mode occurs in event of extreme input voltage condition or complete mains failure. The battery system along with the
During battery mode an alarm sounds every 10 seconds. This will change to 2 beeps every 5 seconds when battery runs low (approximately 2 minutes remaining). Each load/battery level indicator represents a 25% capacity level. As capacity decreases, fewer indicators remain illuminated. Mains LED will flash every second indicating the UPS is operating from battery mode.

Battery mode supports a full rated load for approximately 5 minutes before it shuts down. To increase this time, turn off non essential pieces of equipment (such as idle computers and monitors).
WARNING: Turning off the UPS while in battery mode will result in loss of output power.

If high or low voltage conditions occur, the PowerSure™ Interactive UPS will automatically correct the mains voltage by either lowering or raising the input voltage condition. The UPS will continue to correct these conditions indefinitely, without draining battery power.
