8 Routine Maintenance
8.1 Routine Maintenance
Due to the influence of environmental temperature, humidity, dust and vibration, the internal
components of the frequency converter will age, leading to potential failures of the frequency
converter and reducing the service life. Therefore, it is necessary to implement daily and
regular maintenance of the frequency converter.
Daily inspection items:
Whether the sound changes abnormally during the operation of the motor?
Whether there is vibration during the operation of the motor?
Whether the installation environment of the frequency converter has been changed?
Whether the cooling fan of the frequency converter works normally?
Whether the frequency converter is overheated?
Daily cleaning:
Always keep the frequency converter in a clean state.
Clean the dust on the surface of the frequency converter. Prevent dust from entering the
frequency converter, especially the metal dust.
Remove the greasy dirt on the cooling fan of the frequency converter.
8.2 Regular Inspection
Please regularly check the places that are difficult to check during operation.
Regular inspection items:
Check the air duct and clean it regularly.
Check whether the fan is damaged.
Check whether the screws are loose.
Check whether the frequency converter is corroded.
Check whether there are arc traces on the wiring terminals.
Main circuit insulation test.
PROMPT
When measuring insulation resistance with a megger (please use a DC 500V megger),
disconnect the main circuit cable from the frequency converter. Do not use an insulation
resistance meter to test the insulation of the control circuit. High voltage test is not necessary,
as it
’s completed at the factory.
