Is this a triphase or monophase AC motor?
The motor is a single phase motor with an extra winding combined with a capactor to create a rotating field.

This because a single phase motor can not turn by itself. So a rotating field of some kind is required.

The connection diagram is clearly indicated on the id plate.
By placing the shunts on the left side in the vertical sense (U1-Z2 and V1-U2 the motor ccw. Placing them in the horizontal sense (U1 - V1 and Z2-U2) makes the motor cw. 
Since the motor has two capacitors in series ( 300 uF for starting) and 45 for running there should be also a centrifugal switch inside to short out C2 when running
