I was going to replace the stock snk power supply in my cabinet with a new meanwell psu that I have, but there are a few terminals on the stock psu that I dont recognize. They are marked fg, h and n. can anyone help me identify them? Thanks

Ok I'm pretty sure fg is frame ground. So If my new psu does not have fg can I just connect to ground instead? Also I still can't find what the h and n connections mean.. I assume the n connection is ac\n, but would that mean the h would be equivalent to ac\L?

FG is field ground.

Unfortunately, I don't have any photos from my old U4 showing the wiring off the PS-I would just follow the wires from the PS to their locations. Shouldn't take more than five minutes.

It would appear that is just your AC line. Hit them with a meter or just follow the lines coming in and out. Should be pretty easy.

H= Hot
N= Negative
FG = Field Ground
