Lx_, I can't tell from your post if it was/is clear to you that I suggested lifting only what APS refer to as the "safety ground", as opposed to the "neutral" wire.  In most systems, the neutral is white, and the "ground" is green.  In the USA, this would ba a fourth lug on a 220 service plug/outlet.  My comment on the "dedicated home run (neutral)" means a dedicated, "unbroken" neutral wire running continuously from the PP alone, clear back to the main neutral/ground bus, in the main service box.  If indeed noise on the neutral wire is a problem, then this represents one's best chance to quell such systemic ground noise.  If any problems getting through the PP arrive via the "hot" wire(s), then no amount of messing with wire configuration will stop the noise; only unplugging the thing would do it.

Best regards,
Paul
