Hooking up the Topaz Isolated Transformer

Detail pictures of the Topaz were added in my Powee’s system.
 Thanks 

What is the purpose of the Electrostatic Shield in this power transformer? What if I left it open?

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?

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
