I am in the middle of installing the PD4135 and have a similar question. I installed a small project box above the back of the PD4135 cabinet to route and connect the 12 VDC wiring. I installed a ground bus bar to connect all of the ground wires from each circuit, converter, and battery. I also installed a terminal block to make it easier to connect the wires from the converter to the TD circuits. I attached the positive (10ga Red) wire from the battery to the terminal opposite the positive wire (10ga Red) running from the 12VDC side of the converter. As has been discussed earlier, there is another 8ga red wire coming from the 12VDC side of the converter that is connected to a fuse block containing a 40amp fuse. This fuse is described as the "Reverse Battery Protection Circuit" which blows in the event that polarity is switched on the battery leads. My question is, what do I connect this wire to on my terminal block? Do I run a jumper wire to the positive battery lead? I have attached a photo of my setup. The terminal block is on the right of the small project box. The bottom pair of terminals contain the positive lead from the battery coming in from the left and the positive battery lead going to the converter on the right. I have placed the "Reverse Battery Protection Circuit" lead on the top right terminal. As stated before, what attaches to it?
