Howdy all - Looking for a schematic or service manual or info on the
charging circuit of this 800 VA UPS. The Inverter works perfectly and
there's 120 vac line voltage up to the PCB, however it shows no charging
on the battery lines. Does this UPS relay switch to inverter upon AC
line input failure normally or is the inverter in operation normally as
in a no-break mode? I'm not sure if I'm seeing just a failure to charge
or a failure to recognize and switch to a valid AC mains input.
Any help appreciated
