Help! Needed! Installing PD 4000

I'm installing the PD 4000 power center to replace an old Magnetek. The AC side looks straightforward I understand where I'm going to have to terminate everything. But the DC side I'm not quite understanding. I see where the two lines going to the battery to charge it have to terminate. But then for the fused leads there is only one black wire for each one. What I don't get is where you attach the rest of the circuit for each of these. Like patch them into one of the battery leads that doesn't make sense. Has anyone installed one of these That can tell me or give me pictures of how this works? Much thanks in advance!
  • SOLUTION Found! Finally broke down and called progressive dynamics. After questioning the tech for 20 minutes I finally got the secret out of him. This is nowhere mentioned in the installation guide, there's no illustrations of this, not even a hint to someone who is not a professional electrician. The secret that is nowhere mentioned in any of the their literature is... You need to install an additional circuit breaker that jumps to the hot bus. With out that installed the AC all functions, the DC all functions, but the AC will not run the DC. With that circuit breaker and jump everything works including the converter charging the battery beautifuly. And we were right about the DC negative, run everything to the terminal out going to the negative battery.
  • A follow up on this install. After running all negs to wire screw then to the negative battery heres the results. All DC works, all AC works, but there seems to be no function from the actual converter. The system does not see to connect the AC to the DC side to charge the battery. When I read the voltage across the battery feeds, I only read the voltage of the battery.
    UGG!
  • Ok, I think I will run all the DC neutral's to a wirescrew. Then jump over from that with one connection to the battery negative. I will let you know how it all works out. Thanks everyone for the input.
  • Looked at the install pdf Found 2 diff ones-
    pd4000 manual
    Page 3 (labled page shows the verticle bus on far right NEU
    This oneshows stacked neu & grd buss bars-top one neutral, bottom one ground.
    Dont see seperate 12v neu bar- nor is it mentioned using same buss for ac/dc neutral.
    Using jumper (as ISBRAM outlined, from -batt to added buss would work-might use buss bar from old converter, radio shak etc.
    Mine a PD4600/ Mag9300 replacment also has common ac/dc neu bar.
  • If you dont have a dc ground buss bar I would think you could make something from Home Depot work. All you need is a buss bar hooked up to the negitive side of the battery or the negitive converter output lug. Just use a proper sized wire for the negitive feed to the buss bar, it should not be fused.
  • DIF, I noticed that with the Series 5000 panel the DC- buss is optional. I rather imagine that the PD4000 is the same. There is no mention of a DC- buss anywhere in their ads or PDFs for installation or trouble shooting.

    Is there a buss bar for the commons/ground?

    No I don't see one except for the negative post of the battery input. Do I just run
    all the grounds to that?

    The fuses already on the board are for reverse battery protection and maximum load, if I understand your question you’re asking about the branch dc circuits.
    There are twelve branch circuits running up and down in the center of the panel, the factory doesn’t install fuses in them so all you see are the terminals on the board that the fuses plug into.
    There is a place to attach the wire to next to each fuse holding terminal pair for that circuit on the back of the board, then you have to install the proper size fuse for that circuit.

    There is already a black wire connected to each branch fuse holder, and the fuses are easy. But let's take the pump as an example. There are two leads from the pump. If I connect say the black one to the wire already connected to one of the branch circuit terminal fuse leads what do I do with the other wire going to the pump. I do not see a common bus like those I see for the AC.
