3-Minute Warning
Shutdown Imminent
Figure 16. Battery Capacity Indicators
If battery capacity becomes low while in Battery mode, the indicator
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. For UPS and
Extended Battery Module (EBM) runtimes, see Table 10 on page 49.
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.
