Hooking up the Topaz Isolated Transformer

Hire an electrician, you are dealing with lethal voltages. 

The wiring diagram is clear, but be sure to pay attention to how the center taps are wired, that is what changes it from being isolation to step down.

I think I am able to connect wires myself. I have ran 4 dedicated lines from the main panel to my music room without any help.
But before I start, I still really need help from our community to confirm the connections in the diagram is correct. The reason I am asking is because when I open up the unit, I saw the shield wire hooked up to X4 and H4 which contradicts to the diagram.
 Thanks
