I'm just about ready to hook up my JLM power supply, but I'm a little confused about how to hook up the primaries to the IEC power plug.

If your not familiar with the JLM world power transformer then there are two terminals,

"N" goes to the 0v primary and a switch for 230v or 115v
"A" goes to a fuse then splits to a 120v primary and the switch

Soooo, which terminal is hot and which is neutral?

 
Figured it out, black wire is 0v. 

If any one is familiar with this set up, I have the proper 48v but my other DC voltages are low.  I'm reading 18v and should have 24v

I'm using the 2x12v transformer
The AC on the secondaries is 14v
Terminals A and C (reading at 14v) are connected to separate AC terminals on the AC/DC board
Terminals B and D both go to the 0v terminal

much thanks
