Heatsink
The module heatsink fins pick up dust from the cooling air. The drive runs into
overtemperature warnings and faults if the heatsink is not clean.
Cleaning the interior of the heatsink
WARNING! Follow the safety instructions, page 14. Ignoring the instructions can
cause physical injury or death, or damage to the equipment.
WARNING! Use a vacuum cleaner with antistatic hose and nozzle. Using a normal
vacuum cleaner creates static discharges which can damage circuit boards.
1. Ensure that the drive is disconnected from the power line and all other
precautions described under Safety in installation and maintenance on page 14
have been taken into consideration.
2. Undo the fastening 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. Blow compressed air upwards from the opening and, at the same time, vacuum
from the top of the drive module.
