Hello, long time lurker here with just enough knowledge to be dangerous 
.
Did some searching but want to be 100% sure on this as we are dealing with mains power.
Using the power supply in the attached, 120V AC to 24V DC. As you can see, earth is not required. So, my question is, can I use this to subdue some of the noise from the bluetooth module shown in the picture above the power supply? I have a jumper on it, green cable, right now and it lowers noise, but not completely eliminates it. Just want to make sure I don't create some weird potentials. Thanks!
