4.2 Maintenance

Ensure that the heat sink at the rear of the inverter is not
covered.
Clean the contacts of the PV load-break switch once a year.
Clean by cycling the switch to on and off positions ten times.
The PV load-break switch is located at the bottom of the
inverter.
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 at the inverter base.
To clear obstructions, clean using compressed air, a soft
cloth, or a brush.
The temperature of the heat sink can exceed 70°C.
