1. Preparation First of all, the user should be notified to organize the cabinet without affecting the normal operation of the user. Then, according to the topology of the network, the existing equipment, the number of users, the user group and other factors, the wiring diagram and equipment inside the cabinet are outlined.

1. Tie the cable tie at the beginning of the root of the cable with a cable tie, if there are too many cables, the number of the network cable is divided into two or many parts from the center, but the demand ensures that each part of the network cable is connected, because the next step is simple. 2. According to ...

11. What is the definition and classification of secondary circuits? Answer: The secondary circuit is used to monitor the measuring instrument, control the operation signal, all the low-voltage circuits of the relay and automatic devices are called the secondary circuit, and the secondary circuit can be divided into (1) current circuit according to the power supply and use; (2) Electricity ...
