BATTERY MODE OPERATION

Battery mode occurs in event of an extreme input voltage condition or complete 

utility failure.  The battery system supplies power through the DC-DC converter to 

the inverter to generate 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).  The AC Input LED will extinguish, and the Battery LED will illuminate 

to warn that a utility problem has occurred.  Each load/battery level indicator

represents a 20% capacity level.  As capacity decreases, fewer indicators remain 

illuminated.  Refer to the Troubleshooting Guide.

For battery run times, refer to the Typical Battery Discharge Curves.  To increase 

this time, turn off non-essential pieces of equipment (such as idle computers and 

monitors) or add the optional external battery cabinet.

NOTE:

 External battery cabinets can only be added to rack-tower (RT) models.

CAUTION:

 Turning off the UPS while in battery mode will result in loss of output 

power.

Figure 2 displays approximately 61-80% battery capacity remaining.

BATTERY RECHARGE MODE

Once utility power is restored, the UPS resumes normal operation.  At this time, 

the Battery Charger begins recharging the battery.
