[Overdriven]

[QUOTE=mistercrash;401698]I haven't read all the posts in the thread so sorry if this has been discussed. I have read in here that if you go with two server PS to have a 24V power supply, the two can't be touching because you have to remove the AC ground on one of the units. I hope I understood correctly. This guy here says that he removed the DC ground on one of the units instead retaining the AC ground on both units so the boxes can touch with no problems.

I just finished reading the entire thread from the link posted above. The only thing that's a little scary is on page 4. But the scenario described is also easily prevented. I'll quote the important bit here and save you some thread searching.

"The power supplies have 4 terminals, two for each power supply. You can use a jumper between the two middle terminals to put the power supplies in series and use the outer two for 24v (47amps) or you can jumper both the red and blacks to each other and put the power supplies in parallel mode where you have 12v (94amps).

You can also wire for series and run one charger on the outside posts, then plug another charger into each power supply to get 12v.

The only thing you need to watch for is that plugging a charger into each power supply while in series mode makes one charger's chassis ground for one power supply but also DC+ for the other which means that setting it on top of the charger can cause a short.

Because of this It is recommended that you only use the grounded power supply for 12 while in series mode.

Now that I'm thinking about it, I should probably make a diagram to mail out with the kits." See link in previous post on page 4 for diagram.
