Troubleshooting
The Eaton 9355-F47 Unirom UPS 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.
NOTE
Battery functions are disabled when an ultracapacitor module is installed.
