SNE is not PME. I'm not sure whether to answer because generally if your installing a ryefield board you should know the answer to this. Do you know what SNE is? Or why the link would need removed?

SNE = separate neutral and earth..PME = TN-C-S = protective multiplay earthing..
on my experiencies i never see SNE system anywhere..in my opinion SNE its very rare used system but im not sure..theorically neutral conductor its same as earth conductor..both of them come from the earth..
