Meanwell Wiring - Need some help

DFason · 06/02/2010, 07:16 PM

Real quick question.

I have a LPC meanwell driver and I am at a stopping point. Something real easy but I just need to make sure.

The blue and brown wires which is positive and negative? Also on the cord going to the wall there is no color coding only one with white writing on it, ground, then solid black. Which is positive and negative on that.

Thanks in advance!

In AC you talk in terms of line (+) and neutral (-) so on your plug the Black is line, white neutral and green is ground. I believe the meanwell is Brown line and Blue Neutral.

I have read that for the meanwell line and neutral can be interchanged.

You can on most AC equipment but it's a good habit to do it right.

I ran into this problem recently, after getting support from seller.. either wire can be hooked up to the + /- of power cord.

Just go to rapidled.com and look at the PDF of the ballast. When I did mine I checked it out about 100 times. Free to download them your sure. Who knows why they chose those stupid color combinations anyway???

That is IEC( International Electrotechnical Commission) color codes. It is a European thing as is the CE rating on the ballast..

IEC (most of Europe) AC power circuit wiring color codes.

Function ........... label ... Color,IEC Color, ... old IEC
Protective earth . PE ...... green-yellow ........green-yellow
Neutral ............. N ........ blue.................... blue
Line, single phase L ......... brown ................ brown or black
Line, 3-phase ..... L1 ....... brown ................ brown or black
Line, 3-phase ..... L2 ....... black ................. brown or black
Line, 3-phase ..... L3 ....... grey .................. brown or black

The + & - symbol are not used when referencing AC current because in simple terms the hot alternates between both + & -. The symbol for AC is an AC sine wave inside a circle which I haven't figured out how to do in a post.

Get a meter.
Learn how to use it.
Empirical perception knows no substitute.

"Get a meter.

So you are saying that you can tell which is the hot & which is the neutral by looking into the meanwell with a meter?

Good luck with that
