Message Description
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 &
bypass abnormal
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.
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.
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.
Remote power- on The UPS was powered on remotely. This will display in the log whenever the event occurs
Remote shut- o The UPS was powered on remotely. This will display in the log whenever the event occurs
