Not sure I understand how you expect to hook this up.
First .. you seem to want to hook your TNC up to the battery of the UPS.
The battery of the UPS is designed to power whatever is plugged into the
110vac (or whatever power you have) sockets of the UPS. If you attach an
external load to the battery (your TNC) then I'm not sure the charging
circuit of the UPS will work properly.
Second .. what good is a powered TNC if your radio is not powered?
