The probable causes for the damages: bearing wearing, or aging fan blade.
Judging standard: Please check if there is any cracking in the fan blade, and if there is abnormal shaking
sound when it starts.
The probable causes for the damages: the poor quality of input power, high ambient temperature, frequent
abrupt loading change, or aging electrolytic capacitor etc.
Judging standard: Please check if there is any liquid leakage, if the safety valve is extruding, and the
measured values of direct capacitance and insulation resistance etc.
9.4 Inverter Storage
The performance of electrolytic capacitor will be degraded by long-term storage, so regular maintenance by
powering-on is a must. For the inverter stored for a long time, a powering-on test every half a year for more than
half an hour each time is strongly suggested.
Attentions:
For inverters stored for more than two years, users should power them on gradually by using a voltage
regulator. Otherwise, there might be risks of electric shocks and explosions.
