Newbie- 350-36 power supply

[csmoak25]

I recieved a plug in type wall adapter with my 4030 package, do I cut the end off the adapter and wire it to the power supply
There are two wires on it, one black and one black with a grey colored stripe
Does the black go on the AC ground on the power supply
Black with grey strip to hot on powersupply

There is also a neutral hook up on the power supply in between the two mentioned above. I only have the two wires to hook up so do I just leave that one open.

Also, the power supply has three V+ and three V- each one of these go to Stepper driver correct?

Hi csmoak25. I'm REALLY glad you asked this question first.

The wall wart is the 5V DC PSU for the breakout board. It's supposed to be plugged in to the wall outlet. If you cut off the plug, you will also cut off the Voltage reducing transformer and rectifier. THEN, you would be connecting 120V AC directly to a BOB that's expecting only 5V DC. Much smoke will ensue. This sounds expensive to me, and you might want to refrain from doing it--Unless you have a lot of money and LIKE fireworks.

There is also a neutral hook up on the power supply in between the two mentioned above. I only have the two wires to hook up so do I just leave that one open?

There are three AC connections. Hot and neutral are the main power connections. Ground is only for ground.

Also, the power supply has three V+ and three V- each one of these go to Stepper driver correct?

Correct. If you add a fourth Axis, Just double up on one set.

EDIT: It just occured to me that you might be asking if you should use the wall wart as a PLUG, cut off the OTHER end, and wire it to power the PSU?

NO! Find an old Washing machine or something with a 3 wire plug. Cut off this wire and use it to power your PSU from the wall outlet.

"There are three AC connections. Hot and neutral are the main power connections. Ground is only for ground."

About that... How do I determine which is which without setting myself on fire? And on my PS there are 3 symbols: N, L, and a symbol.

Also, the OP asked:

"There are two wires on it, one black and one black with a grey colored stripe."

I understand that this is for the BOB. But, does the standard coloring scheme dictate that black is negative, gray stripe is positive?


Sorry for the ridiculously simple questions.

Hi zrxer. Nice first post--It's about time you posted something. Welcome to the Zone!

If you don't already have one, you should invest $3 for a Harbor Freight multimeter.

When you look at a standard three prong electrical outlet, the "Hot" connection is the small one, usually a black wire. The Neutral connection is the larger one, usually a white wire and the AC ground is the round one.

N stands for neutral, L stands for Line or Hot Voltage. The symbol is the AC ground connection.

The only way to be sure on the wall wart is to use the DC Voltage setting on the multimeter. When it reads Voltage, and no minus sign before it, the wire connected to the black lead of the multimeter will be the Negative wire, and the Red the positive.

CR.

Great thanks! (Got a few more questions, but I'll be starting a new thread).
