RS485 interface and network configuration description
Note:The gateway can pair up to 16 sub-devices
1.Enter the gateway network configuration mode (host mode),the sub-device "Status"indicator light fashes blue,and enters the network configuration state;
2.Press the sub-device network configuration button to configure the network.The curent sub-device is paired successully,and the sub-de-vice"Status"indicator light flashes red;
3.Pair sub-devices in sequence;

Installation dimensions
1.The device is suitable for standard 35mm railinstallation.When installing,just clip the device into the rail and fix it with a buckle.
2.According to the actual power distribution management and line laying design requirements,select and use the loT module and thespecifcations of the electrical box that meet the needs,and instll them in the order of the modules shown in the figure.Each module isconnected with a 5PIN data cable specially made by the manufacturer.
3.The circuit breaker should be installed verticlly.When the handle is in "/OFF",the contact is in the disconnected state.When the handlemoves upward,the contact moves in the closing direction;
4.The nominal cross-sectional area of the copper wire for connection that matches the rated current of the cicuit breaker is shown in the tablebelow.
