The basic idea of the electrical control design is a kind of logical thinking, logical control law to ensure electrical safety and to meet production requirements, we can say is a good design. However, in order to meet the manufacturing of electrical control equipment and use requirements must be reasonable electrical control of the process design. These designs include the structural design of the electrical devices, electrical equipment, the overall configuration diagram design and the part of the total wiring diagram electrical assembly drawings and wiring diagram design, but also some of the components directory, inlet and outlet technical data of the number and list of the main material .

Electrical equipment in general configuration design tasks according to the working principle of the electrical schematic and control requirements, the first control system is divided into several components (these components are known as components), according to the complexity of the electrical equipment, each component divided into several components, and adjust the connection between them, and then sorted out according to the electrical schematic wiring between various parts of the inlet and outlet. Overall configuration design based on the electrical system of the general assembly drawings and wiring diagrams in the form to express the figure should be signaled in the form to reflect the location of some of the major components and the part of the wiring relationship between alignment methods and the use of the line trunking and pipelines.

The general assembly drawings, wiring diagrams (according to need can be separated and together) is grouped into a complete system in accordance with Division design and coordination of ministries. Overall design for the entire system to focus, compact, under the conditions of the space allows, the heating element, noise and vibration of electrical components, as far as possible be placed farther away from the other components or isolated; large-scale equipment for multi-station, should also consider the convenience of operation of the two places; the power switch, emergency stop control switch should be placed in a convenient and obvious location. The overall configuration is designed to be reasonable or not related to the electrical system of manufacturing, assembly quality, will affect the convenience and quality of the electrical control system performance to achieve its work reliability, operation, commissioning, maintenance and other work.
