What are the wiring requirements for the power terminal and 4G antenna of a 4G general circuit breaker?

Component
Key Wiring Requirements
Precautions
Power Terminals​
1. Voltage Matching: Ensure the circuit breaker’s operating voltage (e.g., AC 220V or 380V) matches the supply network.
2. Identify Line and Neutral Wires: For single-phase circuits, strictly distinguish between the line (L) and neutral (N) wires. Terminals are usually marked (e.g., “N” for neutral).
3. Wire Specifications: Use copper wires of appropriate gauge and ensure they are securely tightened.
Always disconnect power​ before working to prevent electric shock.
4G Antenna​
1. Interface Connection: Firmly screw the SMA connector of the 4G antenna into the port labeled “4G” or “ANT” on the circuit breaker.
2. Installation Location: The antenna should be kept away from metal obstructions​ and placed as close as possible to a window or outdoor area with good signal reception.
3. Orientation and Fixing: Ensure the antenna is oriented vertically upward​ and properly secured using a magnetic base or bracket.
Avoid excessive bending of the antenna cable and prevent water ingress at the connector.
