Please see the grounding scheme below.
In order for the device to be a class 1 device, it needs to have the chassis as protective earth. This is accomplished by running a conductor from the AC MAINS input to a ground stud on the chassis.
However, if I also have my analog ground also connected to the chassis, doesn't this make my protective earth functional ground?
How should this be wired to meet class 1? Should all the ground be tied to the chassis or only the earth from AC?
Thanks!
