Maintaining

● The internal charging indicator light of the frequency converter must be turned off or the power supply must be cut off for 10 minutes before the frequency converter can be inspected or repaired, otherwise electric shock may occur.

● Only professionally trained personnel can maintain the frequency converter, otherwise electric shock or personal injury accidents may occur.

● Do not leave conductive objects such as metals inside the frequency converter after repairing it, otherwise it may cause damage

● Before reusing a frequency converter that has not been used for a long time, it is necessary to charge the internal capacitors of the frequency converter. A voltage regulator should be used to slowly increase the input voltage of the frequency converter (which should not exceed the rated input voltage of the frequency converter), otherwise accidents may occur
