Troubleshooting

The Powerware 9155 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.
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 93).
Possible Cause
A utility failure has occurred and
the UPS is in Battery mode.
The battery is running low.
The UPS does not recognize the
internal batteries.
S
Action
The UPS is powering the equipment with
battery power. Prepare your equipment for
shutdown.
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.
Verify the battery circuit breaker is in the ON
position. If the condition persists, contact your
service representative.
