The motor is presently connected for 115 volts. Applying 240 to it will result in way more current than it can handle, thus tripping the breaker.
To connect it for 230 volts, first remove the brown wire from its post. Next, remove the white wire from its post and push it onto the post the brown wire was on. Then, either find a place near the bottom of the terminal box that has a plastic post and push the brown wire onto it or just tape up the end of the brown wire so that it cannot touch any other terminal.
One of the incoming power wires goes to one of the terminals with a nut, the other incoming power wire goes to the other terminal with a nut.
