UPS has sensed inverter fault and it will run on bypass.
Possible Solution:
Restart UPS to recover from the fault, do manual restart of UPS by switching off the output, disconnecting battery cable at the rear panel, turning off the input power supply and reconnecting the battery cable and input.
In case if error persist even after trying the above troubleshooting, log the complaint.
