Hi,
i have a SUA1500i UPS and after working for a random amount of time all LEDs start blinking and it stops working.
If someone knows how to fix this ,please answer.

Hi Radu, welcome to APC Forums.

Is it all the LEDs or just the six center LEDs that are blinking? If it's the second one, it is what do we call as the AVR relay fault. This happens whenever your UPS either boost or trim the voltage that it is getting from the power source and this sometimes causes the unit to drops its load. Here in the US we normally replace these units that manifest this scenario. I suggest that you contact the APC Customer Care Center for your region.
