Installation instruction
1. The protector connected in serial between the signal channel and the protected device
2. Connect the input terminal to the signal channel, and the output terminal to the protected device, reverse connection prohibited
3. Connect the earthing wire of the protector to the equalizing ring of the lightning protection system
4. The protector should be periodic inspected by the professional staff after the thunderstorm season.
