Structure and Dimensions
Installation should comply with relevant local standards and follow the installation dimension.
1) Install 4 expansion bolts and 2 screws on the wall according to the installation size map. (The screws and the wall should leave a bit space between them.)
2) After let in the cable, install the user information transmission device on the wall by screws.
3) Open the cabinet door, tighten the 4 screws and secure the user information transmission device to the wall.
4) Take the cable to the terminal with reference to the wiring instructions.

•  The resistance between each signal line and the earth should be greater than 3 mΩ.
•  System grounding should use insulated copper core wire of 4.0mm2, and the ground resistance is less than 4 ohms.
•  Distance from the bottom side of the user information transmission device to the ground should be between 1.2m to 1.5m.
•  Front operating distance should not be less than 1.2m.
