(1) After turning off the power supply, allow at least 5 minutes to pass before beginning any inspection or charging process. Ensure that the LED indicator is completely off to avoid the risk of electric shock. This waiting period allows the internal capacitors to fully discharge, ensuring a safer working environment.
(2) Only qualified and trained personnel should perform repairs, inspections, or part replacements. Before starting any work, remove all metal accessories such as watches, rings, and bracelets to prevent accidental short circuits. Always use insulated tools to further reduce the risk of electrical hazards.
(3) Unauthorized modifications to the device are strictly prohibited. Such actions may result in serious electrical shocks, damage to the unit, or even fire hazards. Any changes should only be made by authorized technicians following proper procedures.
(4) Before performing any repair on the inverter, it is essential to verify the input voltage. Connecting a 380V power supply to a 220V inverter can lead to severe damage, including blown capacitors, varistors, and power modules. This kind of mistake can cause irreversible harm to the system.
Inverters typically consist of sensitive semiconductor components, making regular daily checks crucial for maintaining their performance and safety. Environmental factors such as temperature, humidity, dust, and vibration can significantly affect the lifespan of internal components and lead to unexpected failures. Therefore, it's important to maintain a clean and stable operating environment. Regular maintenance and monitoring help identify potential issues early, preventing costly breakdowns and ensuring long-term reliability. By following these guidelines, users can ensure the inverter operates efficiently and safely over its entire service life.
