Where did you get the second quote? The one about the neutral.

Have you checked your local electrical codes about the proper way to wire something for the system you have? Might clear up the neutral thing for you. Here the ground and neutral are "bonded in the box" not at the device. I can not see yours being any different, I am sure you have a transformer with a center tap providing power to you.

BTW, you never said why you want to do this or what you think the benefit will be.
