Power supply proper hookup question
« on: May 15, 2021, 10:47:49 am »
Hey all,


I wanted to double check that I have this correct as I dont feel like starting a fire today :)
If you guys could have a look I would be very very grateful.



L = Live/White
N = Neutral/Black

(-) = Ground/Green

COM = neutral/black
COM = neutral/black
+V = Live/Red
+V = Live/Red

+V ADJ = for adjusting voltage

Thanks!
Trebeck

You've got the AC Live and Neutral wires reversed.

L = Live/White Black
N = Neutral/Black White


The "upside-down christmas tree" 3rd connection (Green wire) from your AC power cord is Ground, often referred to as Frame Ground.
- Ground metal-frame parts, trackball housing, coin door, etc. here.
(*** Exception - If you have a monitor with an isolation transformer, DO NOT ground it here. ***)

The 4th and 5th COM (common) are grounds (-) for DC power. (Black wires)

The 6th and 7th V+ (positive voltage) are the operating voltages (+) for DC power. (Red wires)

Yah and when you win at street fighter.  They are not automatic but that would include more code than I could handle.  :cheers:
