SUA1000i cold start gives Overload warning with nothing attached

[Anonymous user]

Hi, My SUA1000i will not cold start properly - it tries to, then gives a continuous beep with a red overload light - but there is nothing at all attached to the UPS ! Running a self-test via Powerchute results in a pass.

Why is it doing this ? I need to to cold start for an oddball application (i.e. an extremely low power load (<10 watts) in a location that has no mains electricity). I can find no mention of the warning or the cold start procedure in the manual.

Any ideas ???

I have the same problem. After a 10 - 20 times to start without power.
