3.1.5 Replace Cooling Fan
If the inverter continued to operate after the cooling fan trip took place, a protective function will be
activated due to overheat in the cooling fan. Increase in temperature may reduce the lifespan of
major components. Make sure to solve the problem in the cooling fan before operating the inverter.
If the cooling fan has been operating longer than its (optimal) replacement period, this may lead to
low performance of the inverter or the cause of inverter failure. The replacement period of the
cooling fans is 3 years. Replace the old cooling fans with the new one.
The instruction replacing the cooling fan is categorized by capacity as shown in the table below.
Capacity
0.4~4.0kW
5.5~22kW
30~75kW
Replacement of 0.4kW~4kW
