With a machine that can not be harmed by running in the wrong direction for testing purposes the phasing is unimportant, hook up all three lines and run it and note the rotation, if backwards switch any 2 lines and it will run in the other direction.
Please note that your machine being a grinder starting it in reversed rotation may unscrew the grinding wheel if installed, for testing run the spindle without wheels or mounting hardware. I have read that connecting the created leg from a rotary converter to sensitive control circuits may sometimes cause problems but have never seen this myself, I have worked on 2 installations where the created output leg was 30-40 volts higher then the input.
