Output

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 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.
