(1) For direct lightning Protection, in the P5 full color display support structure installation of lightning rod, indoor LED display or next to a tall building LED display, you can not consider installing lightning rods.
(2) for the steel structure of the counterattack, the steel frame structure and outdoor P5 Full-color LED display of the shell connected, do a good equipotential, and do a good grounding, grounding resistance is usually less than 10 ohms, resistance if not up to the requirements, it is necessary to do additional artificial grounding network. Lightning arrester should also be well grounded.
(3) for the power line on the induced lightning flow, in the power supply line to install single-phase or three-phase power supply lightning protection device. The link area of the phase line can not be less than 10mm square, and the connecting ground area cannot be less than 16mm square.
(4) to the signal line on the induction of lightning flow, the signal line to install signal lightning protection device. The signal arrester is based on the system's signal interface, if the network cable is installed on the signal lightning Protection device, serial interface to install DB9 Interface Lightning Protection device.
