Fan

Inverters generate heat during operation, which is dissipated via built-in heat sinks and fans. For this purpose, the ventilation ducts and fans must be kept free of contamination.

If problems occur, check whether the ambient temperature of the inverter exceeds the upper limit. If so, improve ventilation to lower the temperature. If the fan emits abnormal noise, replace the corresponding fans in good time. Please contact your support team for assistance with this.

Vacuuming ventilation ducts

To ensure many years of trouble-free operation, regularly vacuum the ventilation ducts.

POSSIBLE DAMAGE

Risk of damage when blowing out with compressed air.

When blowing out the ventilation ducts with compressed air, fine dust particles may find their way into the bearings of the installed fans and damage them.

• Do not use compressed air, vacuum the inverter's ventilation ducts instead.

• Remove detritus consisting of leaves, dust, insects, etc., especially in the vicinity of the ventilation ducts.
• For example, use an industrial vacuum cleaner and vacuum the ventilation ducts and immediate surroundings.
