I've got a F02 error message on my Back-UPS 1500 when i cut my home power down, and the unit doesn't take over, there is just no power out...omegle xender
The unit seems working normally when turned on, no error, exept if i plug an outlet in the lower "surge only" socket, it immediatly make appear the F02 error.
I've tested my battery, i've got 26.4V. I've also disassembled my unit and take a look, i see nothing suspicious... and i've also tested the two "40a fuses" but they works.
I've only a basic knowledge and can't find where is come from. Maybe there are other fuses to test or something else?
I need some help to resolve this.
Thanks in advance
