10.2 Inspection and Replacement of Wearable Parts
Some components in the AC drive will wear out or deteriorate in performance during use. To
ensure stable and reliable operation of the AC drive, the AC drive should be subject to preventive
maintenance and replacement of components when necessary.
1)
Anti-dust filter
The dust filter is a filtering device out of the air inlet of the AC drive, used to filter dust and
other particles, and it is recommended to replace and clean it once a month. Replacement method
is as follows:
1. Push the square hole of the protective mesh cover upward.
2. When the bottom of the protective mesh cover can be titled over the square hole of the
door plate, pull the protective mesh cover outward from the bottom; take out the anti-sheng Mu
inside the protective mesh cover.
3. Replace the new anti-exit plate, and then put the shield assembly into the square hole of
the door plate.:
