The instructional video suggests doing a bench test of the unit before installing in roof of van, which seems like a good idea. Modularmaker (Daniel), showed me a power supply in the electronics area capable of outputting 12v, which is the voltage of my Nomadic X2 aircon. In the video, the guy does a very thorough job of connecting the unit to test it, but I think it could be simpler:
But obviously I’d like to be safe, and could use someone who knows about electricity to get it connected right. Anyone around now? Or later today (or even tomorrow)?
