I put my 2nd QB together today. It’s a 260 kit from HLG. Here’s how I did it:
I started by placing the boards on the heatsync so that there is a +/- connection at the top and bottom. This allows them to be wired in-series. Basically I screwed one down and the flipped the second one over and screwed it down. Everything is pre-drilled so there is no guessing.
I mounted the driver to the top (fin-side) of the heat sync with the supplied nuts and bolts, but I didn’t take a picture of that. I then took the output side (DC) from the driver and directly wired one to each board. I used the brown as live/hot and the blue as negative.
I then took the input side (AC) of the driver and wired that to the supplied electrical cord. They supply waygos and a waterproof housing. I used the waterproof housing because I wanted to. The waygos are probably easier, but this seems more secure to me. Anyway, if you look into the housing, one terminal has brass connectors, and that’s the one I used for the hot.
After that, it was simply completing the circuit by connecting the +/- on the other side of the boards. I cut a small piece of wire (supplied with the kit) to fit between the boards and BOOM!
