POE Surge Protector

Working principle:
Surge protector link to the be protected front-end equipment, when transmission lines were happen to the lightning and other instantaneous overvoltage shock, the impulse current through the surge protector protection branch will discharge into the earth, and the output voltage limit in the device allow voltage range. ensure the safety of operation equipment.

Installations, Use and Maintenance:   
1 Installation instructions
* Protectors access system before, first check grounding resistance,
  generating should comply with the requirements specification.
* Protectors by protection equipment front-end, access to reliable
  connect.
* Using short and thick grounding lines as possible as you can to
  connect with the Earth-termination system.
2 Precautions:
*Protectors have input (IN), output (OUT) mark, output terminal
  and protected, don't connect the device to connect. Otherwise it
  will cause the protector the damage, the equipment can be protected.
*Due to plug sockets connected factors such as loss of poor should
  be caused by increased connected or replace protector.
*Users Can’t remove protector of each fasteners parts, in case cause
  damage, affect the normal work.
 
3 Protector examination
* With three 6.3.1 in table "Ω x 1" gear measurement protector
   input and output to the HPVV between about 4.7 Ω resistance;
   If open, do not normal, protector should be replaced.
