SUA3000RMI2U dead after startup attempt

[Anonymous user]

Hello folks,

I did sth wrong.. I started up a totally fine working sua3000rmi2u, batt voltage about 52. But while startup I had some loads on it, and unplugged the mains before or during the battery check, it should have been a test 😞

Now its dead, no light on the display, nothing. Yes I replugged it all in as intended. Mains input capacitor is chirping a little, but thats it. Batt voltage fine, mains fine, but its dead. Powerchute, not previously installed, declines installation because of missing UPS (attached by USB).

I got some spares arround here, but only parts, like relais, capacitors and such.

Could some relais be stuck? If so, witch one?

Im deeply concerned about this as I need it and theres no money rigth now for an replacement..

Thans a lot for your help!

cheers!
