Hi just got a couple of EMI filters from www.soigeneris.com - nice quality.

However looking at them they have 3 inputs (Live, Neutral and Earth) but only a Live and Neutral output.

Any ideas what is the best way to wire the Earth? I have googled and it is suggested that the output should be looped from the input and then others where you should do this but put ferrite rings in the Earth.

e.g.

Any help appreciated.

thanks
