Message Description
Output off due to
overload and bypass
abnormal
The output is off 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 off, voltage is
not zero
This occurs when the output is off 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 off shortly.
Output short A short has occurred on the output. Check the output cables and for any equipment that may have shorted.
Rectifier fault
The rectifier is off because the bus voltage is out of the acceptable range when the rectifier starts. Contact Vertiv Technical
Support.
Rectifier overload
The output power is larger than the rectifier overload point. Check that the input voltage meets the output load, if the mains input
falls to 176 V - 100 V, the load is derated linearly from 100% - 50%.
Remote power on The UPS was powered on remotely. This will display in the log whenever the event occurs.
Remote shut- off The UPS was powered off remotely. This will display in the log whenever the event occurs.
Remote shutdown Any mode shutdown was initiated by the dry contact input. This will display in the log whenever the event occurs.
REPO
Shutdown caused by the REPO terminal Normally-Closed contact input opening. This will display in the log whenever the event
occurs.
Restore factory
defaults
On the Maintenance page, Restore Factory Defaults has been set while the UPS is in the stand-by state. This will return settings
to their factory settings.
Shutdown due to over
temp
During the UPS operation, the system checks that the heat sink temperature exceeds the setting range. If over temperature,
please check:
• Ambient temperature too high or not
• Dust is blocked or not
• Fan fault or not
System over temp
Internal heat sink temperature too high, and the inverter is off. The alarm can only be silenced if the heat-sink temperature is
lower than the alarm setting. The system can automatically start after over temperature fault is solved. If over temperature, please
check:
• Ambient temperature too high or not
• Dust is blocked or not
• Fan fault or not
Turn on fail
The UPS does not start because there is no mains/utility power or it is outside of the range of the voltage required to supply the
full load. Check the AC input power.
UPS has no output
Both Inverter and Bypass are not supplying power due to the UPS output being turned off remotely or via the LCD or are
unavailable due to no input power or input power out of range. Check that UPS is on and input power is available.

5.2.7 About Screen
The About screen offers tabs that list information about the product.
• Product tab - shows UPS identification information, firmware versions, and information about the communication
card (when the card is installed).
