I'm installing a 120v single phase SMVector VFD for a roof-top exhaust fan.
Line voltage is 120v and the fan (load) is also 120v
I am not sure where the neutral connection lands for the motor in the VFD. When I power up the VFD I get line voltage on all three load terminals. U-V-W. I've searched extensively online for the answer with no luck.
I've tried connecting the load neutral ahead of the VFD with the line neutral but get an error on the screen. F_01 1
Any input would be great.
Thank you
