If you talking about the output from the converter then check to make sure the 'green' wire is not actually a yellow and green earth wire first. Use a multimeter set to resistance to check you have continuity between it and a metallic point somewhere on the converter frame .
The black wire will probably be a neutral and fir the most part can be ignored at this stage
The three red wires will be the phases ( although its rare to have 3 identical colours used for the 3 different phases)
Plug the bench grinder in first connecting the three red's .to the three wires from the grinder motor that are not the earth wire. ( find the earth in the same way as you did fir the converter) uf the grinder spins in the wring direction, simply pick two of the red wires and reverse them to the wires connected to the grinder motor....
If your not confident, ask a friend that knows a bit about electrics.... Normally its not difficult to work out which wire us what.
