To do this, insert your finger into the top of the
space between ventilation grid and enclosure and
remove the ventilation grid laterally.
2. Clean the ventilation grids with a soft brush, a paint
brush, or compressed air.
3. Re-attach the ventilation grids to the inverter.
The ventilation grids must be attached according to
the inside inscription
("links/left" and "rechts/right").
