punching machines and so on. Please be aware of the possible damages that greasy oil may cause
to your drive:
1. Electronic components that silt up with greasy oil may cause the drive to burn out or even
explode.
2. Most greasy dirt contains corrosive substances that may damage the drive.
Solution:
Install the AC motor drive in a standard cabinet to keep it away from dirt. Clean and remove greasy
dirt regularly to prevent damage of the drive.
