Show a picture of the back of the motor where the wires are connected.
According to your plate data, there
should be 5 posts (connections.) For 230 volts, connect the blue wire to the #5 post (disconnect from the #3 post.) and the white wire to post #3 (from the #1 post). This will give you 230volt 12 amp clockwise rotation. For counter clockwise rotation (CCW) switch the #2 post with the #4 post wires (red and black.)
