denman is a splendid one to behold

You may still have a problem with the wiring if this is a 3 wire hookup.

Here is the wiring diagram for this unit.

Here is the install sheet

In a 3 wire hook up the Neutral (white) and the earth ground are the same wire.
So if the machine frame is not connected and a live wire (black or red) should short to the frame the frame becomes live. Touch it and a ground and you will get a shock.

This does not apply to a 4 wire hook up as Neutral and earth ground (green) are separate. so the green goes to the frame and the Neutral is not connected to the frame.

I would check that it is wired correctly.
