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

Installations, Use and Maintenance:
1 Installation steps
* 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 removes protector of each fasteners parts, in case cause
damage, affect the normal work.
3 Protector examination
* With triple-use measure table "Ω x 1" measurer the input middle-line
and output middle-line of the protector, the resistance should in
between about 4.7 Ω; If open, do not normal, protector should be
replaced.
* With triple-use measure table "Ω x 10K" measurers the line-line
resistance ,the result need to be 400 Ω, line-surge earth-grounding
resistance need be ∞, If not, the protector should be replaced.
