Installation And Maintenance
1.This product series in the protected equipment signal circuit, and close to the protected equipment.
2.The input(IN) and output(OUT) cannot be reversed; the input(IN) is the lightning intruding end,
output (OUT)is connected with the protection device.
3.For the normal work of SPD, grounding is very important, the grounding wire cross-sectional area is no
less than 4m square meters and as short as possible.
4.Lightning protection gate needn't special maintenance, but it's long-term energized, so need messenger to
inspect regularly, especially in the thunderstorm season, after the lightning strike, it should be inspected
on time, if found that the loop signal is abnormal, removing protection gate, loop signal will be back to
normal, it means Lightning protection gate has been damaged or life has ended, replace the new lightning
protection gate on time.
5.The outside length of Coaxial line is more than 30m,it should be in the coaxial two ends with lightning
protection gate, to ensure the best lightning protection effect.
