Hi Folks,
I have installed a MultiPlus Compact in my camper set up, it's all working fine on 12v but when I connect shore power, the RCD on the shore power supply trips within a couple of seconds. When I disconnected the Earths from the PE input/output everything works as it should and nothing trips.
I have the body of the unit earthed to the body of the van. I have tried it with the incoming earth from shore power earthed to the van and not earthed to the van, but this doesn't seem to make any difference.
Do I need to change the settings of the relay?
Any help appreciated.
