Here are a couple pictures of the mains hookup in my cabinet. Red wire is not used. (bought the wrong cable at Lowes)
For what it is worth, my salesperson confirmed it is correct.
Ok never mind. I guess I cannot upload pictures.

The black and white are the two legs of 120 from the 220v circuit.
The ground is connected to the cabinet.
I plugged it in and flipped the breaker and nothing happened, but I still want to have a licensed industrial electrician look it over before I go hitting any power buttons.

Cover the white wire with black or Red tape or shrink tubing just at each end and that part will be fine the Grounding is not and will have to be reworked

First remove the white wire from any Hot 240 volt line feeding the machine. White should never be used for Hot or live wiring. Use the Red wire for the other side of the 240 volt line. In other words Black on one hot and Red on the other hot. Green or bare should go to the equipment ground in the machine and the ground buss in the power or service panel.

If you did not have the Red wire you could mark the White with either Red or Black tape or paint at both ends, and be legal here in the US, not sure about Canada.

To me it looks correct or will be when you change the wire colors. Wether or not you turn the power on is up to you but your supplier told you it was ok??

Yes my supplier said it was correct but I have someone coming out to look at it just so I am sure. I made the change from white to red as you suggested. The cable I bought from Lowes had black, red and white lines. I'm always thinking in 120v terms so I used black and white and left the red unused. I switched it leaving white unused now. So as long as one leg goes to L1 and the other goes to N, there is 220v between them correct? Now I need to figure out the grounds. I wish I could find a book on CNC electrical/electronics.

The reference you are looking for is NFPA79, Electrical Standard for Industrial Machinery.
You might be lucky to find one on the web, there was a slightly older version in PDF out there.
For machinery cabinet enclosure work I prefer to use stranded conductors throughout, TEW/MTW/TR64 etc, or something close if you use sheathed cable.
