Note:With a special connector series in the loop,impedance connectors are 50Ω,75Ω;joint type has N,F, BNC, L16,7 / 16 and other models,determined by the user based on the device being used to protect joints.

 

 

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 without special maintenance, but its 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 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 more than 30m,it should be in the coaxial two ends with lightning protection gate, to ensure better

   lightning protection effect.
