After reading the manual for the third time... it says the ups unit is 1250va it also says the transformer is a step-up. but there were two in the unit a small one and this large one. This large one ran to the batteries, through the fuses on one of the center legs. the others ran to the board in various lacations. the 120v side ran to the board also. So I think Im trying to use it backwards. I have read that thats ok,,, but is it?
well looking at the drawing again, they were using it backwards... or both ways... hmmm
