Re: How to wire 3 phase motor in deferent electrical networks ?
Hi,
for a TT network, you could connect PE to the PE connection and N to the W2/U2/V2 connection.
Usually there should be no current on the N line, so during normal operation it makes no sense.
Re: How to wire 3 phase motor in deferent electrical networks ?
So in TNC I can/should connect PEN to engine cower ? In TT I don't have PE from electrical network and I must create earthing system by myself with metal spike in ground. So IT and TT electrical network are basically same for 3 phase engine (N not used). Do i think corectly ?
Re: How to wire 3 phase motor in deferent electrical networks ?
Long story short. You have to connect phase lines to coil terminals and PE / PEN to engine cower. In TT You just must connect cower to GROUND by yourself. N should not be connected. Problem solved.
