U1 and V1 are the common terminals of the windings. Connect them to the output terminal W
of the solar pumping inverter. Connect U2 to the output terminal U of the inverter. Connect V2
to the output terminal V of the inverter. (Note: Use the screws equipped with the inverter.)
Connect S4 of the inverter to COM in short circuited manner.
