Goodrive100-PV Series Solar Pumping VFD
U1 and V1 are the common terminals of the windings. Connect them to the output terminal W
of the solar pumping VFD. Connect U2 to the output terminal U of the VFD. Connect V2 to the
output terminal V of the VFD. (Note: Use the screws equipped with the VFD.) Connect S4 of
the VFD to COM in short circuited manner.
