Eaton 9355 UPS (20/30kVA) Installation and Operation Manual 164201626—Rev F www.eaton.com/powerquality 87
Chapter 13 Troubleshooting
The Eaton 9355 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 Event Log through the control panel for
a list of active alarms. If an alarm appears with a service code, please contact the Help Desk (see page 88).
Alarm or Condition Possible Cause Action

LED is on.
Continuous beep for
10 seconds.
The battery is running low. Five minutes or less of battery power remains (depending on load
configuration and battery charge). Save your work and turn off your
equipment.
When utility power is restored, the UPS restarts automatically, provides
power to the load, and charges the battery.
Battery Breaker
LED is on.
1 beep every second.
The UPS does not recognize the internal batteries. Verify the battery circuit breaker is in the ON position. If the condition
persists, contact your service representative.

LED is on.
1 beep every second.
The power requirements exceed the UPS capacity
(greater than 100% of nominal; see page 84 for
specific output overload ranges).
Remove some of the equipment from the UPS. The UPS continues to
operate, but may switch to Bypass mode if the load increases. The alarm
resets when the condition becomes inactive.
Overtemperature
LED is on.
1 beep every second.
The UPS internal temperature is too high or the fan has
failed.
