The first indicator indicates an inverter fault. The second one indicates Power Factor Correction (PFC) fault.

These are pretty serious. You could potentially check the UPS Network Management Card log if your UPS has one, even if it wasn't previously configured. But, these are probably not anything you can fix and the UPS may need to be repaired or replace and how that is done may depend in your warranty status.

Do you know when this started - for instance, was there a long outage or power event prior to this fault state so we can understand why this happened? Some back-story might be good.
