13.0 TROUBLESHOOTING
The information below indicates various symptoms a user may encounter in the event the UPStation
GXT2-6000RT208 develops a problem. Use this information to determine whether external factors
caused the problem and how to remedy the situation.
1. The Fault indicator will illuminate, indicating the UPS has detected a problem.
2. An alarm will sound, alerting that the UPS requires attention.
3. One or more additional Load Level/Battery Level indicators will be illuminated to provide a
diagnostic aid to the operator, as described below:
Under fault conditions, the Fault indicators will be illuminated indefinitely while the battery charger
is operational, or for a maximum of 5 minutes while the battery charger is not operational.
If a problem persists, consult your local dealer, Liebert representative or contact the Liebert World-
wide Support Group. Please have the UPS model number and serial number available at the time of
your inquiry.
