Help with fitting a new PSU.

I'm replacing my cabinet PSU (a hantarex US150 or something..) as it's putting out completely wrong voltages. I've got a Primapower psu from swallow amusements however the connectors are a bit different so I want to make sure I'm putting everything in the right place.


The new PSU has the following:

+5v15A
COM
COM
+12v 4A
-5v 1A
(some kind of symbol, looks a bit like:
AC/N
AC/L


The broken PSU has the following:
+5 ( x 3)
GND ( x 3)
-5
-12
+12

unlabelled blue + brown wires which I assume are AC in.
2 green&yellow wires connected to "common ground point".



I am not sure where the GND wires should go. I guess that the blue & brown wires go to AC/N and AC/L but I don't know which is which..

Any help would be greatly appreciated.

GND goes to COM (common ground)

is the earth (green/yellow wire.)

brown is live/active to the mains fuse conventionally, and blue is neutral.

In the states it may be different, they often use black for live and white for neutral, and appliances are often not earthed. The UK standard is much safer imho (PNG uses the same standard, actually Australian standards here)
