Access control system power box lightning protection installation

(1) Avoid installing on the side wall of the house, especially on the side wall of the projected house, so as to prevent direct lightning strikes.

(2) Avoid installation on the side of a pipe where there is a metal pipe, a gas pipe, etc. Especially, the same side wall that is less than 5 meters from the metal pipe and the air pipe can not be installed.

2. Both the power box and the circuit board should be grounded. The grounding wire should be solid and reliable, and the grounding resistance should be ≤ 0.1Ω.

3, wiring should be correct and reasonable. Power lines and signal lines should be placed indoors to avoid outdoor wiring as much as possible, avoiding the same direction and cross wiring as metal pipes, air pipes, etc., and it is impossible to avoid wiring in the same direction as metal pipes, gas pipes, etc. The distance between the two should be ≥ 5 meters. . The wiring should be laid in a straight line to minimize bending wiring.

4. The power source of the power box should be connected to the power socket. When weather is prevented or weather changes may cause lightning, it is convenient to cut off the power in time to prevent lightning strikes.
