Iam getting ready to install and wire up a TECO VFD to my 3 Phase Baldor pedestal grinder. I have not wired up or worked with a VFD previous to this.
The VFD is a 110v input -220 3 Phase output unit. My 110 v shop circuit has the standard URL approved 20 amp, line (black), neutral (white), ground (green) three wire circuit configuration coming out of my sub panel.
So my question is: is it correct that I should connect my 110 v input neutral (white) wire to the L3(N) terminal shown in the attached photo of the VFD?
AND, it should not be connected to the L2 terminal??
Note: the otherwise easy to understand tech manual that comes with the VFD has a diagram that says exactly the same thing as the picture - no instructions on how to wire 3 strand wire to the input side of the VFD.
Basically I've always been confused about which terminals (L1,L2,L3) are normally associated with 110v and 220v 20 amp circuits. - (well, I get the black wire should always be L1 - but have never understood what to do with L2 when wiring two wire circuits with two strand black and white (red) power cords)
Thanks for any clarification anyone can offer.
