Maintenance personnel must perform maintenance and servicing as specified.
-Maintenance personnel must be professionally qualified.
-Before carrying out maintenance, the power supply to the frequency converter must be cut off for 10 minutes before carrying out maintenance work.
Maintenance work can only be carried out after 10 minutes.
-Do not touch the components on the PCB board directly, otherwise the inverter will be easily damaged by static electricity.
During maintenance, please be careful not to mis-match or insert the wires in the wrong way, otherwise it will cause the inverter not to work or be damaged.
or damage.
-Make sure all the screws are tightened after maintenance.
-Please keep the inverter clean and avoid moisture intrusion.
Routine Maintenance
In order to prevent the failure of the frequency converter, ensure the normal operation of the equipment and extend the service life of the frequency converter, the
It is necessary to carry out routine maintenance of the frequency converter, and the contents of routine maintenance are indicated as follows:
Inspection items Contents
1. Temperature/humidity Confirm that the ambient temperature is 0℃~40℃ and the humidity is 20~90% without condensation.
2. Oil mist and dust Confirm that there is no oil mist and dust, no condensation in the inverter
3. Frequency converter Check the frequency converter for abnormal heat and vibration.
4. Confirm that the fan is running normally, no debris stuck and so on.
5. Confirm that the voltage and frequency of the input power supply are within the permitted range.
6. Check the motor for abnormal vibration, heat, abnormal noise and phase failure, etc.
7. Check whether the terminals or connecting wires are loose, broken, poor contact and other phenomena
8. Check whether the radiator is blocked by dust and debris.
