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 180
days. To change the automatic battery test schedule, see §3.5 "Setting Test Schedule" in the
Guide
.
Follow the procedure below when conducting a manual battery test. However, if the UPS has performed a
backup operation within 12 hours 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 12 hours.
