Please help !!

I have a schematic for Single Phase 220 v A.C. Wiring for a lathe.

The schematic shows connections to the Electrical Distribution Panel labeled U1, V2 and Z1.

Can anyone please help translate?

Which one is the Neutral?

Thanks so much !!!!

If you have the meter, check to see if you get equal resistance from one lead to the two others - that should be the ground.

Lacking that, open up the accrees to the motor and trace the leads to the motor. The plate that covers the wiring connections should have a diagram on it that will show what is what.
