I have an Electro ADDA C80M-2 0.75kW single-phase blower motor that I need to hook up, switched, to power a cyclonic dust separator that I've built. I thought it would be a piece of cake: pop off the wiring cover and red-to-red, blue-to-blue, green to earth. But this is what I found:
The dark world of electric motor schematics with Z2, U1, Cr (switch?) et cetera. Bit much to expect line and neutral marked, I suppose?
If I'm reading the schematic correctly, it's currently set up to rotate in the clockwise direction and I've attached the earth terminal, thanks to the nice symbol on the casing, but I'm afraid I don't have confidence in which terminal to take live and neutral to.
Please help if you can.

Pictures should help:
As @Asmyldof stated, the motor has no concept of hot or neutral, so the polarity of the AC connections is not important. Connect one of them to hot, and one of them to neutral. The motor will turn the same direction even if you reverse these connections. To reverse the motor, you have to remove the metal jumpers, and reposition them as indicated by the diagram.
Note that you absolutely should ground the motor housing, but this is a protective measure (the yellow/green-stripe wire is the earth/ground connection), but ground is not neutral.
