MESSAGE DESCRIPTION
Battery test fail
The voltage of the battery was low when the periodic or manual self-test was
run. Battery replacement is recommended.
Battery test started
The battery periodic self-test or manual self-test was started. This will display in the log
whenever the event occurs.
Battery test stopped
The battery periodic self-test or manual self-test has finished. This will display in the log
whenever the event occurs.
Battery to utility transition
The UPS has transferred the load to the mains power from the battery. This will display
in the log whenever the event occurs.
Battery voltage abnormal
The battery voltage exceeds the normal range. Check if the battery terminal voltage
exceeds the normal range.
Bypass abnormal
May be caused by bypass voltage and frequency outside of range, bypass power-off and
incorrect bypass cables connection.
Check that the bypass voltage and frequency are within the setting range.
Check the bypass cables connection
Bypass abnormal in ECO mode
May be caused by ECO bypass voltage and frequency outside of range, ECO bypass
power-off, and incorrect ECO bypass cables connection. Check that the ECO bypass
voltage and frequency are within the setting range. Check the bypass cable connection
Bypass mode The UPS is on bypass. This will clear when the UPS returns to Normal mode.
Bypass over-current
The load is drawing more current than the UPS is rated to supply in bypass mode.
Reduce the load.
Charger fault
The charger output voltage is abnormal, and the charger is off. Contact Vertiv Technical
Support.
Communication fail
Internal communication is abnormal. Check that the communication cables are
connected correctly.
DC bus abnormal
The inverter is off due to DC bus voltage out of acceptable range. The load will transfer
to bypass if the bypass is available because the bus voltage is outside of the acceptable
range.
DC/DC fault
The discharger is faulty, because the bus voltage exceeds the range when the
discharger starts. Contact Vertiv Technical Support.
EOD turn off
The inverter is off due to EOD. Check the mains power-off state and recover the mains
in time
Fan fault At least one fan is faulty. Check if the fan is blocked or the cable connection is loose.
Faults cleared
The faults have been cleared using Settings > Controls > Clear faults. This will display in
the log whenever the event occurs.
Guaranteed shutdown
The battery has finished discharging, then system shuts down because Guaranteed
Shutdown is enabled (see Guaranteed shutdown on page 37). This alarm will clear when
the UPS is turned on again.
Input abnormal
The rectifier and charger are off due to the mains voltage and frequency exceeding
normal range. Check that the rectifier input phase voltage and frequency exceed the
normal range or that the mains has power-off
Input ground lost
Check that the PE line is well connected and that the alarm can be cleared at the
display.
