I'm using a Multiplus-II 5000 at home and want to make sure that the grounding setup is correct.
AC-in is connected to the grid (which only provides phase/neutral so I connected the PE line directly to the house's ground, as well as the chassis)
AC Out 1, until now, is my whole electrical network so it remained connected to the house's ground without any changes.
I want to add new equipment on AC Out 2 and I'm wondering how I should ground that new line. Should I connect it to the AC Out 2's PE line? Directly to the house's ground with AC-in/chassis/... ? Are all the grounds inside the multiplus connected together in which case it doesn't matter where I connect it?
