Hi,

What is the exact model and serial number of the Back-UPS? You will find the information on the bar code sticker on the back or bottom of the UPS.

Me too. F04 error APC Pro 900 model BR900GI. I did it.

3 defective relays. Check all relays. 

I repaired the equipment just for fun. 

If I knew how long it would take to repair the equipment, I would have bought another UPS. It took me 5 hours and 3 relays.
