   Sorry about the extremely late response - I understand you likely no longer   
   need this information but others may benefit from my reply...   
      
   The color code indicates it's wired for North America. If so, the green wire   
   is your ground from the AC mains. The white wire is your neutral and the   
   black wire is power. If you already know what the black wire is for - how   
   would you expect it to actually work if you went and connected all three of   
   them to power as you assumed you should? You have three wires to work with -   
   which one was going to be used to complete the electrical circuit if you   
   went and supplied power to them all? Please don't mess around with AC (or DC)   
   if you don't understand how it works. Even a 120volt circuit can be harmful.
