The wiring method between the parts and components of the electrical control cabinet should generally follow the following principles:

1. The inlet and outlet lines of switch electrical appliances and control boards are generally connected by terminal heads or wiring noses, which can be selected according to the current size and the number of incoming and outgoing wires;

2. Electrical cabinets, control cabinets, cabinets (sets) and between them and the controlled equipment, using terminal blocks or industrial connectors;

3. Various types of standard connector connections should be used between weak current control components and printed circuit board components;

4. The connection between the components in the electrical cabinet, control cabinet and cabinet (table) can be directly connected by borrowing the terminal of the component itself; The transition connection line should be connected by terminal strip transition, and the end should be treated with the corresponding specification of the terminal block.
