Message Description
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.
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.
Input neutral lost The mains input neutral is not detected. The alarm will clear when the neutral connection has been restored.
Input phase reversed
The mains input line and neutral are reversed. Shut off external input breaker and connect the lines
correctly.
Insufficient capacity
to start The UPS is on bypass and is started with a load greater than 105% of the rated capacity. Reduce the load to
the rated capacity or below to start the unit.
Inverter fault
The inverter is turned off when the inverter output voltage or current exceed the ranges set. If bypass is
available, the UPS will transfer to bypass mode, otherwise the system will power off. Contact Vertiv Technical
Support.
Inverter overload
Inverter load capacity is larger than the rated value, overload delay time is up, inverter shuts down. If bypass is
available, the system will transfer to the bypass mode, otherwise the system will power off. Check the output
load. If overloaded, reduce the load, and the system will transfer to the inverter mode after five seconds with
no alarm.
Inverter relay welded The inverter relay is shorted. Contact Vertiv Technical Support.
Load off due to output
short
A short has occurred on the output. Check the output cables and for any equipment that may have shorted.
Load off due to
shutdown on battery
The system was shut down in battery mode. This will clear when the system is turned back on.
Manual power- on The system was turned on via the display panel. This will display in the log whenever the event occurs.
Manual shutdown The system was shut down via the display panel. This will display in the log whenever the event occurs.
No battery No battery detected. Check the battery and battery cable connection(s).
