Running Automatic Battery Tests

The automatic discharge test, enabled by default, runs during the transition from Float to Rest mode.
After the test completes, the charge cycle restarts to completely charge the batteries and then continues
to Rest mode normally. The automatic test runs approximately once every three months and does not
run again until after three more Float to Rest mode transitions. If a manual battery test is requested, the
automatic battery test timer is reset so it will not run for the next three months.
For an automatic battery test to run:
S The Automatic Battery Tests setting must be enabled for the automatic battery tests to run. (See
the following section, "Configuring Automatic Battery Tests.")
S The batteries must be fully charged.
S The UPS must be in Normal mode with no active alarms.
S The load must be higher than 10%.

You can set the load segments for the amount of time to delay the restart when utility power returns,
using the Automatic Start Delay setting. See "Configuring Load Segments" on page 47. You can also
configure UPS restart to depend on the battery charge level, using the Battery Charge % to Restart
setting from the Settings menu (see page 44).
