I finished assembling, installing and wiring my new 3520b yesterday evening. It was too late to play with the lathe when I finished so I sat down at the computer and online was able to find and read the manual for the Delta VFD ( VFD015S21U ) that came with the Powermatic. The manual makes mention of high humidity, vibration and dust as being undesirable.
The VFD on my lathe has ventilation slots covering almost half of the top of the VFD plastic case. I have not checked the direction of air flow from the VFD cooling fan located on the bottom of the VFD, but hopefully the fan blows upwards to move dust away from the unit.
Do I even need to be concerned about dust getting into the VFD ?
