Installation method：

Ground the null line repeatedly when Long-distance overhead incoming lines enter buildings.

Plug the power phase line (L) and null line (N）into corresponding connector of the electric surge protector and make sure it's firm and reliable. Connect the ground terminal of arrester with the ground lead of lightning protection well (recommended earth resistance ≤4Ω).

Suggested specification of the lead wire: no less than 6mm2, short and straight.
