figured I'd give you folks a shot at it.
I have two APC rackmount ups units. One is a 2200XL model which has a
larger internal charger to support external battery packs. The other
unit is a 2200 model that does not support external battery pack and
thusly has a smaller charger. I want to disable the charger in the
second unit while retaining all of the normal functionality of the UPS.
I want to do this in order to have them share a large deep cycle battery
pack where only the other unit will charge it.
I have taken a few photos of the main board of the ups. I am curious if
anyone is familiar with it or can recognize what I can do to disable its
charger. Perhaps even removing a simple fuse would do the trick, I
dunno. I can do the work, just not sure how to proceed. I do not have
a schematic for this.
