Cleaning the heatsink
The drive module heatsink fins pick up dust from the cooling air. The drive runs
into overtemperature warnings and faults if the heatsink is not clean. When
necessary, clean the heatsink as follows.
WARNING!
Use the required personal protective equipment. Wear protective gloves and
long sleeves. Some parts have sharp edges.
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 16) before you start the work.
2. Remove the module cooling fan(s). See the separate instructions.
3. Blow dry, clean and oil-free compressed air from bottom to top and
simultaneously use a vacuum cleaner at the air outlet to trap the dust. If there
is a risk of dust entering adjoining equipment, do the cleaning in another room.
4. Reinstall the cooling fan.
Replacing the cooling fans
