So what about space in front of panel?
My old NFPA 70 article 110.26 specifies 3 ft working space. ??
Yeah, for anything over 120VAC I recall 42" being thrown around a lot, but I don't own the standard or know that we were truly applying it correctly (yay guessing!)
..... though you'd have VFD powerup time upon reestablishing the safe state of the fence...
