Hooking up the Topaz Isolated Transformer

Thank you everyone,
I just found a picture online related to my particular model of the Topaz. I posted it in my system page. As the image, I am supposed to remove the Shield wires on both input and output H4 X4 and move them to the ground post.
Could you please let me know if my thinking was corrected?

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.
