Appendix 1 Lighting-proof, with Surge-protector
This product adopts air discharge lightning and TVS board-level technology; can
effectively prevent damage to equipment from 1500W (below) instantaneous
lightning strike, waves. However, make necessary protective measures under the
electrical safety for outdoor installation:
z
Signal lines must keep at least 50 meters with high-voltage transmission
lines or high voltage cable;
z
Outdoor wiring must be selected along the roof down;
z
For the open area must be sealed by pipe buried wiring, and pipe using
point grounding, absolute prohibition of overhead wiring;
z
Strong thunderstorms area or areas of high-voltage sensor (such as
high-voltage substations), power must be taken to install additional
equipment and lightning rod and other lightning protection measures;
z
Outdoor installations, lightning protection and grounding circuit design
must consider building lightning protection requirements, and comply with
the relevant national standards, industry standards;
z
Equipotent grounding system must be. Grounding system must meet the
anti-jamming devices and electrical safety double requirements, and may
not be short-access or mixed access with the strong zero grid line. When
separate grounding systems, anti-resistivity less than 4
Ω
, grounding wire
cross-sectional area must be not less than 25 mm ²;

4.
Avoid installing it reversely
It’s designed for ceiling or wall mount. So if installed upside down, such
as installing on the floor, it may cause it out of order.
5.
Please use it according to the required temperature and
humidity
Don’t use it under the circumstance of high temperature or humidity.
Leave it away from heat-generating equipments, such as warm vapor,
stove and so on.
6.

a)
Quick changes from high to low temperature caused by
opening/closing the door occasionally
b)
Used where the glasses can generates fog.
c)
Used in the house full of smog or dust.
If the lens covered with fog generated by water condensing, put the
cover down and clean the appearance with a piece of soft cloth.
