You can perform tests of the built-in and externally connected batteries. You can do this without stopping
the load devices connected to the UPS.
When it is shipped from the factory, the UPS is set up to perform an automatic battery test once every 6
months. To change the automatic battery test schedule, see §3.14 “Setting Battery Test Schedule” in the
User Settings Guide
.
Follow the procedure below when conducting a manual battery test. However, if the UPS has performed a
backup operation within 24 hours (A11H***011) or 36 hours (A11H***111) prior to the test, the result may
show an error. The test should, therefore, be conducted when the UPS has not performed a backup
operation within the last 24 or 36 hours.
The “Green BATT. TEST” indicator starts blinking, and the battery test starts.
The test finishes
in about 90 seconds.
Check the “Green BATT. TEST” indicator for the results of the test.
