The VFD works great to create three phase from 240V. I found the instruction manual difficullt to understand and I needed to do a lot of online research to get my head around the setup. For example, it is very confusing which exact ports to connect 240 +/- wires to (manual just points to RST ports). The section referring to external controls is way too brief. Suggest that you write a technical advisory which provides the basic information needed to hook it up the various controls. Otherwise, the device works brilliantly.
