the nearest I have found is this :-

figure 17 on page 21 shows a low resolution diagram
do two of the wires have short wires crimped on to make the diagonal connections to the switch ???
if you test the continuity between the 4 wires from the motor
I would expect you will find two wires (V1 V2 ) have continuity and they need to be wired across the middle 2 switch terminals
the other two wires (U1 U2) motor wires will go to the start winding that's in series with a capacitor
and will connect directly to the mains supply from the NV release switch
