1. Make sure that all equipment in the electrical control cabinet is well grounded, and use short and thick grounding wires to connect to the common grounding point or grounding busbar. Any control equipment connected to the inverter should be co-grounded with it, and likewise ground with short and thick wires;
2. Flat conductors, such as metal mesh, are used because of their low impedance at high frequencies. The grounding wire is the line that directly connects to the earth, which can also be called the safety return route, and it directly transfers the high pressure to the earth when it is dangerous. Due to the poor insulation performance of household appliances or the humid use environment, the shell will have a certain amount of static electricity, and in serious cases, electric shock accidents will occur;
3. To avoid accidents, you can connect a wire on the metal shell of the electrical appliance, and connect the other end of the wire to the ground. For electrical appliance maintenance personnel, when using an electric soldering iron to solder circuits, sometimes the integrated circuits in the electrical appliances will be damaged because the electric soldering iron is electrified.
4. Wire pipe wiring: all wires that are not in the electrical control cabinet should be threaded, and the pipe wiring has the characteristics of moisture resistance, corrosion resistance, and the wire is not easy to suffer mechanical damage, and is often used in places that bear a certain pressure.
5. Wiring in the cabinet: according to the characteristics of the electrical circuit and the equipment requirements, choose a reasonable wiring method in the electrical control cabinet.
