How do AC ground wires connect to a DIN rail?

My AC ground wires connect to a green DIN rail connector which has metal on the bottom of this terminal and connects to the DIN rail itself (which then is connected to the overall enclosure via back plane). 2 questions: For DC ground, should I use the same green DIN mounts as I am using for AC?

Should you connect a DC power supply to ground?

If the question ‘should you connect a DC power supply to ground, or should you not?’ is posed, the answer is not a straightforward yes or no. In many cases, it will not cause any problems. In fact, it will afford greater safety to ground the common -v of the DC output.

Can a DC ground be connected to the same block?

If you connect DC grounds to same block, you have always DC current in the green block. Sure you can earth the gray DC return busbar if the power supplies already don't. Also the wifi light is accidentally connected to mains earth, it shouldn't. What do you mean by AC ground?

Should I ground a DC terminal?

If this PSU is powering other objects, and they have their own ground, then there is a possibility of creating a ground loop -- 60 Hz magnetic fields will induce a current in this loop; if it is an audio system, the hum could be significant. So, for maximum flexibility, I would not ground the DC- terminal.

Do AC wires have a ground?

When examining the output wires, they only contain a + and a - terminal and very rarely contain a protective earth (ground) connection. Yet for AC systems, this bonded ground system is regulated and required very strictly. The matter of grounding DC supplies can be split into three separate topics:

Should a DC output be connected to a bonded ground?

Often, it is recommended to connect the DC (-) output to a bonded ground in order to reduce or eliminate this common-mode noise. It is also convenient for the sake of measurements when the reference for any DC component can be any metallic object nearby.
