Question about vertical strapping

I have a pre-wired switchcraft patchbay with bussed grounds for every 8 patch points. I do not have a board. I am using individual pres and will want to run phantom from the mic tie line normalled to the mic pre ins. I was told to have these patch points vertically strapped. Switchcraft told me that I just need to snip the ground wire that busses all 8 and solder (or gator clip) a lead between the ground pin of the top point to the one right below it. Is this absolutely all I have to do or do I need to send the ground anywhere else from there? 

If you have any other info that I would need to do this on my own please let me know. Your help is much appreciated. 

Thanks!

Hey Christopher,

Switchcraft told you correctly. Snip the strapped grounds that go from channel to channel. Then just solder a wire from the ground on the top-row to the ground on the bottom-row below it and you will be GVS. That is all that is needed.

One last question. Once each channel is GVS do those individual grounds need to be touching some part of the chassis? Where do the vertically strapped grounds actually ground to? Since the main objective for this is to pass 48V phantom from mic pres to mic I just want to make sure i don't run into any danger.  Thanks again

Hey Chris,

Ground (pin 1 on your XLRs)  will be provided to the patchbays’ ground pin by the input on your Mic Pre via the GVS that ties the two patchbay rows together. Then the GVS will send that ground from the MicPre through the patchbay to your microphone. Phantom will pass down that same ground wire. All will be good.
