    ●This product is the connection method of Shenlian.
    ●Please select the product with the same interface type as the protected equipment.
    ●The lightning protection device should match the working voltage of the protected equipment.
    ●When installing, please connect according to the installation diagram, where IN is the input, OUT is the output, PE is the ground wire, the input terminal is connected to the external wire, and the output terminal is connected to the input terminal of the protected equipment. Do not connect it wrongly.
    ●The PE wire of the lightning protection device must be reliably connected to the ground wire of the lightning protection system, and the connection wire must be short, thick and straight.
    ●The lightning arrester should be tested regularly during its use. If it fails, it should be repaired or replaced in time to ensure the safety of the equipment.
