F.5 Industrial Dust Problem
Serious industrial dust pollution frequently occurs in stone processing plants, flour mills,
cement plants, and so on. Please be aware of the possible damage that industrial dust may
cause to your drives:
1.
Dust accumulating on electronic components may cause overheating problem and
shorten the service life of the drive.
2.
Conductive dust may damage the circuit board and may even cause the drive to
explode.
Solution:
Install the AC motor drive in a standard cabinet and cover the drive with a dust cover. Clean
the cabinet and ventilation hole regularly for good ventilation.
