When shutdown is imminent, the Self Test indicator flashes. 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 connects to the load when the startup is complete.
Diagnostics
The UPS periodically performs diagnostic tests while the unit is
operating in Normal mode, ensuring proper operation. These tests
include:
S Self Test
S Utility Verification Test
S Battery Discharge Test
S Over Temperature Test
The UPS also runs a series of over 20 internal tests when power is first
applied. If a diagnostic test fails, see Chapter 7, “Troubleshooting” on
page 75.
Battery Test on Demand
You can perform a battery test on the UPS while it is operating in
Normal mode by pressing the Output On button. The UPS
automatically distributes some of the load to the batteries for 30 seconds
and tests the battery’s performance.
Battery Start
NOTE Before using this feature, the UPS must have been powered by utility power at
least once.
This feature allows you to start the UPS without utility power. After
utility power has been unavailable for one minute, press and hold the
Output On button until the alarm beeps.
The UPS supplies power to your equipment and goes into Battery mode.
The
indicator remains lit and the front panel displays the percentage
of battery capacity remaining to the UPS. This process should take about
20 seconds.
