4 Maintenance

This chapter introduces basic maintenance requirements, routine maintenance items, maintenance operations, basic fixing
methods and emergency treatment.
NOTE! 1. The maintenance must be conducted under the guidance of related safety regulations. 2. Even if the system
disconnects all AC inputs and battery inputs, the rectifier capacitor still needs to discharge for a period of time. After
measuring the DC bus voltage is below the safety voltage by a multimeter, then you can maintain DC bus and device
connected to the DC bus.
