Maintain the Inverter
The cooling of the inverter is exclusively through natural convection, therefore the cooling system is
maintenance free.
Periodically, based on site conditions, visual inspection of the cooling fins is recommended to identify any
debris accumulation that could occur. If found, the debris must be removed to ensure that the convection
cooling is not inhibited.
Cleaning with high-pressure cleaners is prohibited.
Annually, the DC switch has to be operated without electricity 5 times.
