Furthermore, the current of the fan (cooling fan) should be kept within a certain range during normal operation. If the current fluctuates greatly, it may indicate that the fan (cooling fan) has a mechanical jamming problem.

[0057] 2. Extend equipment life: Good heat dissipation conditions help extend the service life of frequency converters.
