Cleaning the interior of the 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.
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 18) before
you start the work.

described under Grounding (page 21) have been taken into consideration.
3. Undo the attaching screws of the handle plate of the drive module.

another room.
