What power supply do you have?
The supply wires are marked on the layout, so you have to figure out how to connect those strips (the three top ones, in this case) to the corresponding supply voltages.
If you have a supply with Eurorack-style 10-pin connectors, you can create a 10-pin to 3-wire adapter on a small separate piece of stripboard (or a spare corner of your main board, if you have the space) and then use wires connect the power strips there to the corresponding strips on the module.
