Folks, if you don't know about electricity, or terms of it, please don't say anything.
I am truly waiting on the post for someones widow that so and so was working on the wiring on their whatever and got electrocuted.
That being said.
The transformer in the picture is not 3 phase. It can be used with 3 phase power, but it's not fed with all 3 phases.
The reason it's labeled with 220 and 480 is that 220 or 480 3 phase is the voltage developed between any two phases of the line.
As a side note, if you measure actual 3 phase to ground / neutral you get 277 for 480 and 120 if it's 208/220.
To feed the transformer you are going to hook 2 phases to it. One will connect to H1 with a jumper over to H3 and the other phase will connect to H2 with a jumper to H4. X1 and X2 are the 110 volt AC output that will run to the control circuits for the DC motor.
On a side note, if you were to feed the transformer with 480. The two phases would connect to H1 and H4 and a jumper would be placed between H2 and H3 for correct wiring.
And remember electricians or electric guru's are cheaper than doctor bills, lost wages and funerals.
If you don't know for certain what you are doing, or feel the least bit of concern hire a professional or find a buddy that does this stuff and ply him with pizza and beer (beer after the work is done. It saves in the long run
