The Power Distribution Board (PDB) is primarily wired with the use of Wago connectors, which to my knowledge has never been explained in a manual. For the connections along the long sides of the PDB, you have a small slot right above a round hole. To secure a wire in that hole, put a screwdriver in that slot and lever it either up or down, I can't remember which, and while it's levered, insert the wire. Then pull the screwdriver out.

These PDB connections make use of strong springs to secure the wires, which by default block the hole. Levering a screwdriver in that slot unblocks the hole by raising the spring, and pulling it back out drops the spring back on the wire that you've inserted, securing it in place.

Be sure to use appropriate gauge wire for wiring purposes. Personally, by team uses 6AWG wire for battery - switch - PDB connections, ~10-12AWG for 40A distributions from the PDB, and ~16-18 for 20A-30A distributions from the PDB.
