MESSAGE DESCRIPTION
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 o external input breaker and
connect the lines correctly.
Insuicient 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 o 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 o. 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 o. Check the output load. If overloaded, reduce the
load, and the system will transfer to the inverter mode after ve seconds with no alarm.
Inverter relay welded The inverter relay is shorted. Contact Vertiv Technical Support.
Load o due to output short
A short has occurred on the output. Check the output cables and for any equipment
that may have shorted.
Load o 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).
On maintenance bypass
The UPS is operating in maintenance bypass mode. This will display in the log
whenever the event occurs.
Operating on inverter
The UPS output is being powered by the inverter. This will display in the log whenever
the event occurs.
Output disabled
The system is in standby state, and the dry contact shutdown is enabled. Check if the
shutdown dry contact is enabled.
Output o due to bypass
abnormal
The bypass voltage or frequency is outside the acceptable range, and the bypass is in
stand-by mode. Check that the input is normal.
Output o due to overload &
abnormal bypass
The output is o due to an overload of the UPS output, and the bypass voltage or
frequency is outside the acceptable range. Check that the input is normal.
Output o, voltage is not zero
This occurs when the output is o and the system detects that there is still voltage on
the output. Check output equipment for backfeeds or contact Vertiv Technical Support.
Output pending Remote shutdown has been initiated, and the system will turn o shortly.
Output short
A short has occurred on the output. Check the output cables and for any equipment
that may have shorted.
Rectier fault
The rectier is o because the bus voltage is out of the acceptable range when the
rectier starts. Contact Vertiv Technical Support.
Rectier overload
The output power is larger than the rectier overload point. Check that the input
voltage meets the output load, mains input 176 V ~ 100 V, the load 100% ~ 50% linear
derating.
