Dual PSU wiring
-
Hi,
I'm upgrading my printer (Duet 0.6 and 12V bed, heaters etc) with some TMC2209 silentstepsticks which I intend to run on 24V.
Thus I need to wire up two PSU's.
After failing a few times to design and print a partial enclosure for the mains end of my 12V PSU and a fused mains socket and switch, I got the openbuilds powercase and a meanwell 24V PSU to go with it.Now I'm wiring them together.
Are there any immediately obvious errors or dangers in wiring them up like this?
I noticed the powercase lacks a fuse unlike my previous mains socket. Would it be necessary to wire fuses between the N and L terminals and the mains socket? Max power draw for the PSU's are 3.4A and 4A.
Should I tie V- to mains ground also on the 24v PSU or will I then get a ground loop? (Note I don't have mains ground in the socket right now, but don't want to get bitten in the ass by if when I move.) Should I instead just tie V- together between the PSU's?

Try to get rid of crimps and keep single insulated cables down to a minimum, with mains cables.

@Benny I'm not using a bunch of crimps between the PSUs as shown, just to terminate the wires and attach them to the PSU terminals.
Would tinned wire ends be better? Why?
