During battery mode an alarm sounds every 10 seconds. This will change
to two beeps every 5 seconds when the battery runs low (approximately
2 minutes remaining, but this is user configurable). The AC Input LED will
extinguish, and the Battery LED will illuminate to warn that a utility prob-
lem has occurred. Each battery level indicator represents a 20% capacity
level. As capacity decreases, fewer indicators remain illuminated. Refer to
Troubleshooting section.
For approximate battery run times, refer to the Battery Run Times charts
in this manual. These times are approximates based on resistive load and
an ambient temperature of 77°F (25°C). To increase this time, turn off
non-essential pieces of equipment (such as idle computers and monitors)
or add the optional external battery cabinet.
BATTERY RECHARGE MODE
Once utility power is restored, the UPS resumes normal operation. At this
time, the Battery Charger begins recharging.
!
CAUTION
Turning OFF the UPS while in battery mode will result in
loss of output power.
