I bought a new KBAC 29 single phase input VFD off Ebay and on initial power up the breaker trips. VFD not switched to run mind you. I check my wiring and try again and breaker trips immediately. I never even got to hit the start button? VFD has a bad smell to it. Something just crapped out? Anybody got a clue why this would happen? It's a 230v single phase input, 3 phase output unit rated for 3hp.
