For an HLG-480H-48A you should at !east use 8 strips in parallel. This way each strip get's ~1,25A which is close to its limit. The 100-240v side is AC input! This side is connected to a wall plug(L, N and ground). On the other side you have the DC output. This side has 48v and min. 10A(see datasheet below).
You need to solder wires to the + and - side on the strips(best would be red and black) and then connect all + wires together on one side and all - wires on the other side. 5 port Wago clamps can do this and are pretty cheap. If its done you have one + Wago and one - Wago and all strips are connected in parallel. The only thing to do now is to connect the + and - wires of the driver output to these two Wago connectors and its done. As soon as you plug it in it will lit up and with the build in regulators you can dimm the light between 50 and 108%.
First thing you should do is to figure out its maximum. You turn the current regulator(the right one) fully up than adjust the voltage regulator to the point where it gets not brighter. Leave it at this point it protect your strips incase one fails. Put the rubber nipple back in and use only the current regulator for dimming.
That's it! Lamp is running, voltage limit is set, fixture should work for a long time. You can also add more strips but no less than 8. It's possible to use less strips but you would either not get the full driver output or you would overdrive the strips which can damage them.
Visit ledgardeners website he has a few nice wiring examples or search youtube for how-to vids if you're still unsure how to do it. But it actually pretty easy.
