AudioStatic Wing connect power and jumper settings

Hello,

i have a AudioStatic Wing set but dont no ho to connect the 2 pins wire into the 3 pins connector on print.
If i look to the layout on print a want put it into the right side of the 3 pins connector so the i put the trafo into serial mode for 230volt?

also there is a jumper, i read somewhere this is for voltage selection, but i dont get it...
what are the jumper settings, jumper on or off.

i do not find any manual of these speakers
