8 Maintenance and Cleaning
8.1 Cleaning the Inverter
If the display field is dirty and you find it difficult to read the operating data and operating states of
the inverter, clean the display field with a damp cloth. Do not use any corrosive substances
(e.g. solvents, abrasives) for cleaning.
8.2 Checking Heat Dissipation
8.2.1 Cleaning the fans
If the fan screens are only soiled with loose dust, they can be cleaned using a vacuum cleaner. If you
do not achieve satisfactory results with a vacuum cleaner, dismantle the fans for cleaning.
Procedure
1. Disconnect the inverter from both the DC and AC connections as described in section
7.2 "Opening the Inverter" (page 56).
2. Wait for the fans to stop rotating.

– Press the two latches on the right edge of the fan
screen to the right using a screwdriver and
loosen it from the bracket.
– Carefully remove the ventilation grid.
4. Clean the ventilation grid with a soft brush, a paint brush, a cloth or compressed air.
