UPS Start-Up & Shut Down

Functional Test

26
To test readiness of the UPS, a functional test can be performed.
ATTENTION: Supply to the load is not guaranteed during this test. It should not be carried out if a
critical load is connected to the UPS.
Simulate a mains failure by interrupting the mains supply to the UPS. If the UPS is operating correctly
and the batteries are fully charged, the following will occur:
• An acoustic signal at intervals of 4 seconds will be heard
• The "ON" LED indication will be extinguished
• The "BATT" LED will be lit.
Once the interval between the acoustic signals has decreased to 1 second, the UPS will continue to supply
energy via the batteries for a maximum of 3 more minutes, after which it will automatically switch off.
The load will be supplied from the batteries during the specified emergency supply period. If this does not
occur, see "Troubleshooting" on page 31.
If the test is successful, restore the UPS mains supply. The UPS is ready for operation.
NOTE: The batteries must be recharged before the complete emergency supply period is again available.
