Schematic diagram
Installation and maintenance
1. The lightning protection device is connected in series between the protected equipment and the signal channel.
2. The input terminal (IN) of the lightning arrester is connected to the signal channel, and the output terminal (OUT) is connected to the input terminal of the protected equipment, and cannot be reversed.
3. Reliably connect the ground wire of the lightning protection device with the ground wire of the lightning protection system.
4. This product does not require special maintenance. When the lightning protection device is suspected to be malfunctioning, the lightning protection device can be removed and thenchecked. If the system returns to normal after the system is restored to the state before use, the lightning protection device should be replaced.

●This product is connected in series. ●The power supply must be cut off before installation, and live operation is strictly prohibited. ●The lightning protection device should match the working voltage of the protected equipment. ●The “L/+” on the lightning protection device is the live wire or the positive wire, and the “N” is the neutral wire or the negative wire. ●When installing, please connect as shown in the installation diagram, where N is the input OUT is the output, PE is the ground wire, the input end is connected to the outside line, and the output end is connected to the input end of the protected device. Do not connect it wrongly. ●The lightning protector has working instructions. When the power is turned on and the work indicator is on, it means that the power is normally connected and the lightning protection components are working; on the contrary, the lightning protection device cannot be used and should be repaired or replaced in time. ●The connecting wire should be a multi-strand copper wire not less than the standard requirement, and it should 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.
