Hi,

F04 is a clamp short which means there was a surge or multiple surges that the UPS shunted and after the last surge the UPS could not return to normal state.

You can try to resolve by resetting the UPS

1: Disconnect any attached load.

2: Unplug the UPS from the wall socket.

3: Disconnect the UPS' internal battery.

4: Push and hold the "On" button on the UPS for 5 seconds

5: Reconnect internal battery.

6: Plug UPS in to known good power source.

7: Turn UPS on.

If that does not resolve the issue the UPS should be replaced. If the unit is under warranty contact local Schneider Electric support for assistance. 

Local support contact information will be found at this link.
