Hello, I am running a home shop and would like to use my dryer outlet to power my VFD which is a Lemze 3HP model ESV222N02YXB.

My problem is that diagrams in the Lenze manual only depict 3 wires coming from the power source and I have 4 wires coming from my dryer plug.

On the VFD for the power source there are 4 connection posts, PE, L1, L2, L3. The diagram for single phase 240 VAC on shows 3 connections. Pics attached to help visualize what I am seeing. The second last picture actually shows 4 wires coming from the power source but I am not sure which color wires should go where.

As for electrical codes, I am located in Toronto Canada.

Any help would be appreciated. Thx.
