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 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
Installation steps：
*Before connecting the protector to the system, Make sure
heck grounding resistance and conform to the criteria with
he 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.
Note:
*There are IN and OUT icons marked on the protector, and
he 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.
Protector examination
*Use the Multi-meter with "Ω × 1" range to measure the protector’s
resistance, the value should be around 3.5 Ω ; If not, protector need to be
replaced.
*Use the Multi-meter 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.
