Working Principle:
Surge protector link with the equipment which be protected in the front of the system. When transmission lines were happen to the lightning and other instantaneous overvoltage shocked, the impulse current through the surge protector grounding cables discharging into the earth, and limit output the voltage with the device allow -voltage. Ensure the safety of the equipment.

Installations, Use and Maintenance:
1 Installation steps
* Before connecting the protector to the system, Make sure
check grounding resistance and conform to the criteria with
the requirements;
* Connect the protector to the front of the device firmly.
* Use the short and thick grounding lines as possible as you can
to connect with the Earth-termination system.
2 Note:
* There are IN and OUT icons marked on the protector, and
the OUT port should be connected with the protected device,
please don’t make mistake. Or it will cause damage to the protector,
and also the device can’t be protected as expect.
* Due to sockets connected interface factors caused the loss of poor,
should be replace the protector or maintenance.
* Users Can’t removes the fasteners part of the device, in order to
avoiding damage and affect the normal work.
3 Protector examination
* Use the Multimeter with "Ω × 1" range to measure the protector’s
resistance, the value should be around 0 Ω ; If not, protector need to
be replaced.
* Use the Multimeter with "Ω × 10K" range to measure the middle
line to earth-ground resistance, the value will be around 400KΩ, if not ,
need to replace the protector.
