Installation method：
When the plug of the lightning protection socket is plugged into the mains jack, please make sure that the mains line is normal and the power line (L) and neutral line (N) have no errors.. You can connect the plug of the lightning protection socket to mains jack to ensure the reliability.
When a long-distance overhead line enters a building, the neutral line is grounded repeatedly, and the grounded end of the connection socket or lightning protection ground wire is connected well.
(Recommended grounding resistance ≤ 4Ω)
