1. Use a vacuum cleaner with a plastic nozzle to completely clean the inside and outside of the inverter cabinet to ensure that there is no excessive dust around the equipment.
2. Check the ventilation and lighting of the inverter room, and the ventilation equipment can work normally.
3. Check that the connection between the internal cables of the inverter should be correct and reliable.
4. Check that all the grounding in the inverter cabinet should be firm, and there is no rust at the grounding point.
5. The connecting nuts of the internal cable of the inverter should be tightened again every six months.
6. Check the tightness of all electrical connections, check that there are no abnormal discharge traces in each circuit, and there is no strange smell, discoloration, cracks, damage and other phenomena.
7. After each maintenance of the inverter, it is necessary to carefully check whether there are missing screws and wires, etc., to avoid short circuit incidents caused by small metal objects. In particular, after making major changes to the electrical circuit, the connection of the electrical connection line is correct and reliable, so as to avoid the occurrence of "reverse power transmission".

The inverter needs to be equipped with a braking resistor-Delta
The inverter is equipped with a braking resistor, mainly to consume part of the energy on the DC bus capacitor through the braking resistor to avoid the voltage of the capacitor being too high. Theoretically, if the capacitor stores a lot of energy, it can be used to release it to drive the motor to avoid energy waste, but the capacity of the capacitor is limited.

Introduction of incoming reactor for inverter - Delta
Reactors are also called inductors, and when a conductor is energized, a magnetic field will be generated in a certain space scale occupied by it, so all electrical conductors that can carry current have inductance in a general sense. However, the inductance of the energized long straight conductor is small, and the magnetic field generated is not strong, so the actual reactor is conductive.
