Pin 13 (Ground) on CPC connector.

I am working on one of my CNCCS books and am wiring the CPC, I have never actually used the ground connector on the connector.

What is it used for? Should I connect this to my CNC ground bus bar?

Note that I have connected my PM65 to four different CNC machines and never used this pin. Also on hookup schematics I have found during searches, none have used this pin.

I have connected a few hundred Hypertherm Powermax systems using this cable. Never once connected the ground (and I worked for Hypertherm when I made most of these connections). It is actually a ground that could be used to help solve electrical noise interference issues (if you had them) These issues are rare with a blowback start plasma unit , as all Powermax systems are. So, in most cases there is no need to use the ground connection on the CPC or interface cable. Jim Colt

Thanks, that is kind of what I figured. Since it is for a book, I wanted to make sure.
