Battery Mode

When the UPS is operating during a power outage, the alarm beeps
once per second and the
displays the approximate percentage of battery capacity remaining (see
Figure 36).
When the utility power returns, the UPS transfers to Normal mode
operation while the battery recharges.
If battery capacity becomes low while in Battery mode, the
flashes and the alarm sounds continuously, indicating approximately
three minutes of battery time remaining. When shutdown is imminent,
the indicator flashes.
NOTE Depending on the UPS load, the 3-minute warning may occur before the batteries
reach 25% capacity; the front panel immediately displays the 3-minute warning.
These warnings are approximate, and the actual time to shutdown may
vary significantly. Once these warnings are indicated, immediately
complete and save your work to prevent data loss and similar difficulties.
When utility power is restored after the UPS shuts down, the UPS
automatically restarts.
