Re: [The_Cyndustries_List] Major Power Supply grounding

2010-01-18 by Cynthia Webster

Some of the earlier Power Supplies connected to the green ground jack to the chassis ground but we stopped doing that some time ago.
you Can simply snip the wire to earth if you like, or ad a switch as a ground lifter.

So today I was using my Modcan/Cynthia system and cross patching with my Driscoll/Serge system and ran into some grounding issues.

The Modcan/Cynthia rig is powered with a Cynthia Major PSU and the Serge/Driscoll rig is powered with a power-one supply I got from ebay and wired up myself.

On the PSU I wired, I took the signal ground to my ground jack to use when connecting to other PSU's. Upon examining the Major PSU I found that the grounding jack is connected to the PSU chassis and the earth ground.

After discovering this I remembered I had a Serge PS6 in my closet so I opened it up and the ground jack is indeed connected to the signal ground.

I'm wondering if this is how the Cynthia PSU is supposed to be wired? I can't figure out how it makes sense to wire it that way.

Anyone have an explanation?
