Cleaning the door air inlets (IP22 and IP42, option +B054)


WARNING! Use a vacuum cleaner with an antistatic hose and nozzle. Using a
normal vacuum cleaner creates static discharges which can damage circuit
boards.
Check the dustiness of the air inlet meshes. If the dust cannot be removed by vacuum
cleaning from outside through the grating holes with a small nozzle, proceed as follows:
1. Recommendation: De-energize the fans by switching off the supply unit.
2. Remove the fasteners at the top of the grating.
3. Lift the grating and pull it away from the door.
4. Vacuum clean or wash the grating on both sides.
5. Reinstall the grating in reverse order.
