Some of y'all have asked about isolating the output from ground on the 47A power supplies so the case can remain grounded when operating 2 in series. Here are the steps required. I have tested this and it does seem to work. It takes a lot longer for me to do this than just wrapping the case in clear tape. It may be safer too.
In the pictures below, remember to reassemble it in reverse order.

Remove the side panel and the top. The fan will also have to be removed.
Yes the insulator is taped to the top (red lightning bolt) making it difficult.
Remove the 2 screws and nut.
Remove the two screws at arrows and ribbon connector. Then remove the top screw at lightning bolt.
Remove the board by tilting it and lifting it off the stud.
Shim the 2 screws (red lightning bolts) using #6 fiber washers on each side of the board to isolate the output from ground.
