8-1 Maintenance
INSPECTION AND MAINTENANCE
Inspection and maintenance of the inverter requires professional and
qualified personnel, and pay attention to the following matters：
• Maintenance personnel must follow the specified methods of
maintenance and maintenance.
• The power of the inverter must be turned off for 5 minutes before
maintenance.
• Do not directly touch the components on the PCB, otherwise it will be
easily damaged by static electricity.
• After maintenance is complete, you must confirm that all screws are
tightened.
Due to the influence of the environment (such as temperature, humidity,
smoke, etc.) of the inverter and the aging of components inside the inverter,
various faults may occur in the inverter. Therefore, the inverter must be
inspected daily and regularly maintained during storage and use. Daily
inspection and maintenance refer to the following table：
