The BEP 3.0 uses quick-connect terminal blocks. You use a thin screwdriver or similar to press the orange button you see located at each hole in the terminal block. Then stick in the bare end of the wire and release the button. The wire will be captured and not be able to be removed. Tug on the wire to make sure it is secure. To release the wire, press and hold in the orange button and pull on the wire.
