I have a 4kw Huanyang VFD, single phase in to a 5hp old planer. I only have a one 220v out let in my garage, a 30amp dryer outlet, that is used by several tools.
I typically flip the breaker off, plug in the VFD, turn break on, it boots up and then I hit Run and use the planer.
Saturday I didn't do the breaker, I just plugged it into the wall, it booted up and about 1 minute later a loud POP and it was dead. I took it apart and found nothing burnt.
My dad came by, 40+ year contractor and does his own electrical, and we wired it up again without the ground on a terminal and Popped again. I don't know what that means but my dad thought it was fun
Any ideas? I personally think sawdust got inside. I didn't have it covered like planned to do.
I plan on ordering another one but this time I want to add a toggle switch to turn the VFD on AFTER I plug it into the wall. How do I add a toggle on/off switch?
