Low Battery Warning
Shutdown Imminent
Figure 20. Battery Capacity Indicators
If battery capacity becomes low while in Battery mode, the indicator
starts flashing and the alarm becomes continuous. This warning is
approximate, and the actual time to the Shutdown Imminent warning
may vary significantly.
NOTE Depending on the UPS load and number of Extended Battery Modules (EBMs), the
Low Battery warning may occur before the batteries reach 25% capacity. See Table 9 on
page 56 for estimated runtimes.
When shutdown is imminent, the indicator flashes. Immediately
complete and save your work to prevent data loss and similar difficulties.
If utility power returns before UPS shutdown, the UPS transfers to
Normal mode operation while the battery recharges.
If utility power returns after UPS shutdown, the UPS automatically
restarts.
