UPS Operation

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:

:Self Test

:Site Fault Test

:Utility Verification Test

:Battery Discharge Test

: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 57.

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.
