Product installation:

1. The lightning protection devices is installed in series between antenna channel and the protected device, the output termination is connected with the protected equipment.

2. The ground line of  lightning protection should be reliable connected with  the ground line of  lightning protection system.

3.Lightningproof grounding should be consistent with lightning protection   regulatory requirements, grounding wire should be as thick and short as possible,resistance should be less than 10Ω.

4. When system work fails and doubt SPD is normal or not, you can examine it after removing the SPD, if we restore to the prior state and its system is back to normal, you should replace the SPD.
