VFD found offline and unable to power up.
AC TECH SM 4100 VFD (10HP). On initial checks the line reactor as well as other electrical equipment in enclosure are in good working order. Power is not passing through VFD.
One capacitor out of two capacitors is blown. The very same programming that was used on many other VFDs I installed over the past two (2) years was set.
What could be the causes (high voltage, external interferences, bad electrolytes, etc.)??
There is a straight slit along the blown capacitor. The top of the capacitor seems to have bulged out as well.
