UPS operations 71
Running automatic battery tests
Battery tests rely on backfeeding the utility, using the utility as a load. Some sites might choose to disable
battery testing if their source is not capable of being backfed. Examples of such sources include generators,
other UPSs, and other stiff or soft sources. If a source is not capable of being backfed, the UPS aborts the test
(due to utility failure) and maintains the load and log the event. Further consequences depend on the source
(for example, another UPS feeding the BladeUPS module might trip off).
NOTE: For automatic and manual battery tests, the UPS determines when it is appropriate to run
the test. Battery tests run only when the system is in High Efficiency mode.
To disable battery testing:
1. Press any button on the front panel display to activate the menu options.
2. Select SETTINGS > USER SETTINGS > BATTERY SETUP > Battery Low Alarm.
3. Use the up or down arrow buttons to select Disabled.
4. Press the left arrow button to save the setting.
5. Press and hold the ESC button until the Start screen appears.
Testing the front panel display
To test the LEDs:
1. Press any button to activate the menu options.
2. Select CONTROL, DISPLAY TEST
3. Confirm the selection by pressing the right arrow button.
Press ESC to stop the test.
Silencing an audible alarm
To silence an alarm, press any button on the front panel display to silence the alarm. If the alarm status
changes, the alarm beeps again, overriding the previous alarm silencing.
IMPORTANT:
• Although the audible alarm silences, the condition that caused the alarm to sound may still
exist.
• If a utility power failure caused the alarm, the alarm silences after power is restored.
For information about audible alarm conditions, see "LED and audible alarm troubleshooting (on page 94)."
Verifying the REPO port connection
NOTE: While testing, operate connected equipment in a safe test mode so the effects do not
disrupt critical operations.
After connecting the REPO port (on page 21):
1. Initiate a REPO by closing the REPO contact.
