V560 Series High Performance Closed-Loop Vector Inverter User Manual
9. MAINTENANCE
Many factors such as temperature, humidity, dust and vibration of the use environment, and internal
components aging, wear of frequency inverter, which may lead to hidden fault of frequency inverter. In order
to ensure the frequency inverter of long and steady operation, its maintenance is required in the storage and
the process of use.
After long-distance transportation of the frequency inverter, users should check whether the components are
in good condition, or the screws are fastened before use them. During the normal use period, users shall
regularly clean the internal dust of frequency inverter and check whether the screws are loose.
Due to the high voltage of frequency inverter in service, the wrong operation can result in serious injury or
death, therefore, the power supply of the frequency inverter shall be cut off, and the maintenance operation
after ten minutes after the nixie tube of the frequency inverter panel extinguishing can be carried out.
9.1 ROUTINE MAINTENANCE
Through routine maintenance, all kinds of abnormal condition and abnormal cause can be found promptly,
and the faults and hidden dangers can be eliminated as soon as possible. Thus, the normal operation of
equipment can be guaranteed and also the service life of the frequency inverter can be prolonged. Refer to
the following table for routine maintenance.

¾ The inspection shall be carried out by professional technician, and the power of frequency
inverter shall be cut off.
¾ For frequency inverter with more than half a year storage time, when an electric current is
applied, users shall boost the voltage slowly through voltage regulator to supply the
power, or otherwise will lead to the risk of electric shock and explosion (internal
electrolysis condenser).
