Live and neutral pins of Ultra

[Chaplyga]

My friends. Is it important which one pin of the power connector of Ultra will be the phase and which one will be neutral?

I understand that a C7 connector isn’t polarised, so it doesn’t matter which way round you plug it in. I’ve never paid much attention when plugging mine in.

This very early morning, with eyes not really open, I have written a very long sermon about correct phases as answer, only to notice a bit later that it is the in Germany often so called Euro Stecker/Kupplung. Deleted with shame

There's always just an alternating voltage between both pins and since there is nor further ground as a reference it doesn't matter which is which. Signal ground is not connected to either pin but free floating.

These so called Class II devices (with no safety earth) must provide isolation of the case to protect users from electric shocks. Neither of the power pins must be connected to any part reachable by the user.

You can still try and revert the polarity of the plug to see if there are any unexpected secondary effects, but no matter what you do, the device is safe either way.

That’s why I try to resist posting an hour before bedtime or an hour after waking up (I don’t always succeed) - my brain is in slow motion then…

FYI, there are non-polarized (Type A) and polarized (Type B) plugs. Type A are more common, but Type B do exist. It seems like Wiim just uses Type A.

Here is a type B plug.
