Paul Z. Posted February 19, 2021 Share Posted February 19, 2021 Just to confirm, when not using the ATS, is this the correct connection for proper output voltage sensing? T I/P L = transformer input T I/P N = transformer input AC O/P L1 = transformer L1 output to main panel GROUND = transformer L2 output to main panel AC O/P N = transformer N output to main panel T I/P L1 = not connected AC I/P L = not connected AC I/P N = not connected I'm running the transformers output directly to my main panel, but the PJ 15 kW will not run without this filter/charger board, due to output voltage sensing requirements. I believe that this was how they were originally hooked up from the factory, but I could be wrong. Quote Link to comment Share on other sites More sharing options...
