Hi all,

Sorry for the noobie question, but i would like to use 2 Doepfer PSU 3 in my case but with only 1 power inle, and i'm not sure about the way to plug them together.
I found a scheme (on the Doepfer wbesite) to plug an inlet+switch with 1 PSU3, but i'm not sure on how to do the same with 2 PSU3.

I made a scheme, based on the Doepfer version for 1 PSU, but for my 2 PSU.

Do you think that it's ok to plug the second PSU to the first one

In the Doepfer scheme, the ground is not plug anywhere. Is there any reason Maybe it's not necessary to plug the ground....
In my case, can i do the same thing without any risk
 
Thanks in advance for your help
