11000 VA UPS and 11000 VA EBM: Installation and Maintenance Guide
Possible cause
The external contacts in the rear of
the UPS are configured for remote
emergency power-off operation, and
they are activated.
The load level is at or has exceeded
the configurable threshold limit for a
Level 1 Overload condition.
See "Behavior on overload" on page
37.
The load level is >101% and <110%
of the UPS rating.
See "Behavior on overload" on page
37.
The load is >110% of the UPS rating.
See "Behavior on overload" on page
37.
The battery voltage levels have
exceeded the maximum allowable
limits.
A battery charger fault has been
detected.
The UPS has detected abnormally
high output voltage levels.
The UPS has detected abnormally
low output voltage levels.
The UPS has detected that rectifier
input current limits have been
exceeded.
The UPS has detected that the
inverter output current limits have
been exceeded.
The link or rail voltage has exceeded
its upper threshold limit.
The link or rail voltage has dropped
below its lower threshold limit.
The UPS has detected a fault in the
inverter circuit while attempting a
recovery from Bypass mode or Fault
mode.
The UPS has detected a fault in the
rectifier circuit while attempting a
recovery from Bypass mode or Fault
mode.
The UPS has detected an abnormally
low impedance placed on its output
and considers it a short circuit.
Action
The UPS de-energizes the load and
enters Standby mode. For more
information, see "Installing the remote
emergency power-off" on page 14.
The UPS can support the load
indefinitely at this load level.
The alarm clears when the load drops
below 5% of the set point.
Immediately remove some of the
equipment from the UPS.
The alarm clears when the load drops
below 5% of the set point.
Shutdown is imminent.
The alarm clears when the load drops
below 5% of the set point.
The UPS turns off the charger until
the next power recycle. Contact your
service representative.
The UPS turns off the charger until
the next power recycle. Contact your
service representative.
The UPS transfers to Bypass mode if
supporting the load.
The UPS transfers to Bypass mode if
supporting the load.
The UPS transfers to Battery mode if
supporting the load.
The UPS transfers to Bypass mode if
supporting the load.
The UPS transfers to Bypass mode if
supporting the load.
The UPS transfers to Bypass mode if
available and supporting the load, or
Fault mode if not.

The UPS shuts down after five line
cycles.
