BATTERY MODE OPERATION

Battery mode occurs in event of extreme input conditions or complete utility failure. The battery system along with the bi-directional converter generates power for the connected load.

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. Utility 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.

The figure below displays approximately 51-75% battery capacity remaining.

BATTERY RECHARGE MODE
