i am after pulling a old ups out of storage and trying to get it working again.
its a APC smart ups 700 series. model no. su700inet.
when i plug in the ups (with & without load) the overload light comes on and the ups emits a loud tone. the battery has two bars left in it and the fuse is not pushed out at the back.
i have searched online and there hasn't been much there for this problem. one forum says to replace the overload relay. i have opened the ups and found the relay it seems to be fine. the relay is a SCHRACK RP920124.
thanks in advance to everyone that helps.
