4.2 Maintenance

Ensure that the heat sink at the rear of the inverter is not
covered.
For correct operation and a long service life, ensure free air
circulation for the following areas:
• around the heat sink at the top and side of the inverter
where the air exhausts, and
• towards the fan on the underside of the inverter.
To clear obstructions, clean using compressed air, a soft
cloth, or a brush.
The temperature of the heat sink can exceed 70°C.
