6.5 Cleaning the Ventilation Grids
The ventilation grids must be clean for optimum heat dissipation of the device. Clean the ventilation
grids regularly as follows:
1. Remove the ventilation grids to the side.
3. Clean the ventilation grids with a soft brush, a paintbrush or compressed air.
4. Close the recessed grips with the ventilation grids.
Ensure the assignment is correct. Each ventilation
grid is assigned to an enclosure side on its interior:
Left side "links/left" and right side "rechts/right".
2.
Damage to the inverter caused by foreign bodies.
• Do not remove the ventilation grids permanently. They prevent foreign bodies from
entering the enclosure.
