Heatsink
The drive module heatsink collects dust from the cooling air. If the heatsink is not
clean, the drive can generate overtemperature warnings and faults. When necessary,
clean the heatsink as described in this section.
￭ Cleaning the interior of the heatsink
WARNING!
Obey the safety instructions of the drive. If you ignore them, injury or
death, or damage to the equipment can occur.
WARNING!
Use a vacuum cleaner with antistatic hose and nozzle, and wear a grounding
wristband. Using a normal vacuum cleaner creates static discharges which can
damage circuit boards.
1. Stop the drive and do the steps in section Electrical safety precautions (page 21)
before you start the work.
2. Remove the attaching screws of the handle plate of the drive module.
3. Remove the handle plate.
4. Vacuum the interior of the heatsink from the opening.
5. Carefully blow clean compressed air (not humid or oily) upwards from the opening
and, at the same time, vacuum from the top of the drive module. Prevent dust
from entering adjoining equipment.
6. Reinstall the handle plate.
