Troubleshooting
The Eaton 9140 is designed for durable, automatic operation and also
alerts you whenever potential operating problems may occur. Usually
the alarms shown by the control panel do not mean that the output
power is affected. Instead, they are preventive alarms intended to alert
the user. Use the following troubleshooting chart to determine the UPS
alarm condition.
Typical Alarms and Conditions
The following table describes typical alarms and conditions; check the
Alarm History through the front panel for a list of active alarms. If an
alarm appears with a service code, please contact the Help Desk (see
page 99).

for estimated runtimes.
When utility power is restored, the UPS restarts

charges the battery.
