Standby/Manual Bypass Button
This button controls output power to connected load(s) and has dual
functions: Standby and Manual Bypass.
Load/Battery Level Indicators (4 Green, 1 Amber)
The load/battery level indicators have dual functions. During normal mode
operation LED indicators display the approximate electrical load placed upon
the UPS; and during battery mode operation LED indicators display
approximate battery capacity.
The Liebert GXT2U is equipped with automatic and remote battery test
features. The automatic test occurs every 14 days (this option is user
configurable) if utility 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 Troubleshooting section). The
remote test feature functions with Liebert MultiLink 3 software and can
remotely initiate the battery test.
