Hi,
I want to know how to power up a Automation Direct power supply (STP-PWR-3204).
Currently, I have connected the 120V AC pins G,N,L to various connections to a 10-circuit terminal block which in turn in wired to other components such as stepper drivers, etc.
But to power up everything, I assume that I have to plug this Automation Direct power supply (STP-PWR-3204) to a wall socket and out of the 120V AC pins G,N,L, how do I plug it in to a wall socket ?

Get a pigtail power cable with a standard outlet plug on one end, or just take any cable with a power outlet plug and chop off the other end. If the color coding on the cable is US standard, White is Neutral, Black is Line, and Green is ground. If the color code is European standard, Blue is Neutral, Brown is Line, and Green/Yellow is Ground.

Also note, the 120VAC is the INPUT for this device. Do not wire the devices you are trying to power with this to the 120 VAC input.

But I am still unsure on the power supply wiring instructions... I do get the color scheme for the 3 wires...
I have another power supply that is +12V DC,0V DC as well. I replaced the 2 pins that go into the wall socket by removing them and soldering 2 wires instead. So where do I connect these wires from my 12V DC Supply to the Automation Direct power supply (STP-PWR-3204) which has 120V AC with G,N,L pins?
Another thing is, if I wire the 3 pins (G,N,L) of the 120V AC, then where would the other 3 ends go from respective wires? Do they go to the wall socket directly? Thanks

I'm not 100% sure if I understand what you are asking. So because a picture is worth a thousand words, I offer this graphical representation of what I am trying to say. That will power up your Power Supply, and allow the power supply to output 35VDC and 5VDC.

Tell me more about this other power supply. Every power supply requires a specific input power source (usually 120 - 240 VAC).

Okay.Thanks for your answer.
I got a Standard Three-Prong Plug and Bare Cord Conductor wire. The bare end has 3 wires coming out and only the middle wire is green; the remaining 2 wires on either side are under a black jacket and have brownish strands of wires. I stripped the jacket but all that's visible is the brownish strands on the 2 outer wires on either side. So, how do I figure out the Neutral and the Live wire (assuming the green wire is the ground)? And how should I connect the plug into the 3-prong wall socket?

I'm not sure I understand what you are saying. The other two wires should have white and black insulation. By brownish do you mean copper? The plug should just fit the socket. If it doesn't, you got the wrong one. What country are you located in?

Yea I am here in US and don't worry... I solved this issue and got this thing powered and its working just fine.
Thanks.
