I apologize for any confusion and the diagram was too large so I resized it. I'll try to be more clear.
There is a 480V 3 Phase coming in to a system. The 480V is split to energize two terminal blocks (TB1 and TB2) on the back of the system. Each terminal block has 6 posts. The 480V is further split, where Phase A goes to post 1, Phase B goes to post 2, Phase C goes to post 3, and an identical setup for A/B/C to 4/5/6 respectively. TB1 is suppling an input to power supplies SetA and TB2 is suppling an input to power supplies SetB.
In SetA, power supplies A1/A2/A5 are connected to posts 4/5/6 and power supplies A3/A4 to posts 1/2/3.
In SetB, power supplies B1/B2/B4/B5 are connected to posts 1/2/3 and power supply B3 to posts 4/5/6.
From this setup, we can see that all of SetA (40V power supplies) are connected to one terminal block and all of SetB (400V power supplies) are connected to the other terminal block. My question again, is this correctly wired since all of the 40V power supplies in parallel are tied together and the same for all of the 400V power supplies in parallel are tied together?
I have some uncertainty because both terminal blocks are still being supplied by one 480V 3 Phase that has just been split. That is why my second question asks if it makes a difference if for some reason one of the power supplies from SetA was connected to TB2 or one from SetB was connected to TB1 even though all paths trace back to the same 480V 3 Phase.
