Lightning protection
This products use TVS lightning protecting technology, it can protect the equipment in these situations: momentary
lightning striking power voltage below 1.5W, electrical surge and other pulse signal. But, if you installed the machine
outdoor, should consider practical situations, should ensure the electrical security, and do necessary protecting
measures. Like this picture:
z
Signal transfer wires should stay away from high voltage equipment or wires at least 50m distance ;
z
Wiring outdoor should choose to along under house eaves;
z
In the open zoom, please use sealed steel tube to cover land and wiring, and use the steel tube to touch the land,
forbid to wiring in the air;
z
In strong thunderstorm area, or high voltage area (like high voltage substation), must install special powerful
lightning protecting equipment, and lightning rod, and all these equipments must be installed by professional
worker;
z
The system must be electrical bonding, the earthing device must meet all professional demands both of system
and electricity, and don't connect to strong electrical net wires. When the system earthing alone, the impedance
of earthing device should be less than 4
Ω
, cross sectional area of earthing conducting wires must be smaller than
