5 Maintenance and Cleaning
Check for proper inverter operation at regular intervals. Dirt, such as dust, can cause heat
accumulation, which can lead to yield losses. Check the inverter and cables for any signs of external
damage. Have repairs carried out if necessary.
5.1 Cleaning the Fan
If the fan guards are dirty with loose dust, then you can clean them with a vacuum cleaner. Hold the
pipe of the vacuum cleaner below the fan of the inverter (see Figure). If you are unable to clean the
fan properly, contact your installer who will dismantle the fan in order to clean it.
5.2 Cleaning the Display
If the status LED's or the display unit are dirty and cannot be read clearly, clean them using a moist
cloth.
WARNING
Only qualified personnel may dismantle the inverter fan.
The procedure for dismantling the fan for cleaning is described in the inverter installation
guide.
Cleaning the status LED's and the display unit
Do not use any solvents, abrasives or corrosive substances for cleaning.
