The Liebert GXT3 is equipped with automatic and remote battery test features. The default setting is
for the automatic test to occur every 14 days (this option is user-configurable) if utility power has not
been interrupted. Should the battery fail this test, the red Fault indicator LED along with the A and
C diagnostic LEDs will illuminate and an alarm will sound (refer to 11.0 - Troubleshooting). The
remote test feature functions with Liebert MultiLink and can remotely initiate the battery test.
