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.
