8 Maintenance and Cleaning
8.1 Cleaning the Inverter
If the inverter is dirty and it is difficult to read the operating data and operating states of the inverter,
clean the enclosure lid, the display and the LEDs using a damp cloth. Do not use any corrosive
substances (e.g. solvents or abrasives) for cleaning.
8.2 Checking Heat Dissipation
8.2.1 Cleaning the Fans
If the fan guards are 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 sides as described in Section 7.2 "Opening
the Inverter" (page 48).
2. Wait for the fans to stop rotating.

– Use a screwdriver to press both latches at the
right edge of the fan guard to the right and
dislodge it from the retainer.
– Carefully remove the fan guard.
4. Clean the fan guard using a soft brush, a paint brush, a cloth or compressed air.
