3-Minute Warning
Shutdown Imminent
Figure 32. Battery Capacity Indicators
If battery capacity becomes low while in Battery mode, the indicator
starts flashing and the alarm becomes continuous, 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 62.
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.
