UPS Operation
When shutdown is imminent, the Self Test indicator flashes. These
warnings are approximate, and the actual time to shutdown may vary
significantly. For approximate battery times see the table on page 4.
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 connects to
the load when the startup is complete.

Diagnostics

operating in Normal mode, ensuring proper operation. These tests
include:
