Rui - Have you shut off the blue electric arc? If you have done that, then go back over the wire bridge, go right, past where that arc was, and go right up the next ramp. At the top, on your left is a window - look to the top on the right side of the window, and you'll see the four bars. you need to move them so the opening in the bar is right in the middle - you will see some space on either side of the brace that holds them. When all are centered, the shuttle door will open.

But, ah, my foes, and, oh, my friends -
it gives a lovely light.
