1. The lightning arrester 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 protected equipment and cannot be reversed.
3. Connect the grounding wire of the lightning arrester reliably to the grounding bar of the lightning protection system.
4. This product does not require special maintenance. When there is suspicion of a malfunction in the lightning arrester during system operation, it can be removed and checked again. If the system returns to normal after being restored to its pre use state, it indicates that the lightning arrester has been damaged and must be replaced immediately.
