Ⅶ、Appendix Ⅰ:Lightning and Surge Protection
The Product adopts grade 3 lightning protection technology, which is
effective for avoiding the damage of equipment from pulse signal, such as those
from instant lightning or surge. However, for outdoor installation, necessary
protection must be adopted according to the situation on condition that the electric
safety must be guaranteed.
◎ The transmission line must be at least 50 meters away from high-voltage
equipment and cable, try to arrange the line along the eaves.
◎ The underground sealed steel tube arrangement must be adopted in open
area, and steel tube must adopt one single connect earth. The overhead ground
arrangement is absolutely forbidden.
◎In the intense thunderstorm or high induced voltage area(e.g.: High-Voltage
Junction Box), such methods as the installation of extra superpower lightning
protection equipments or lightning rod must be adopted.
◎ The design of outdoor device and the lightning protection and earthing of
line must meet the requirement of the building`s lightning protection, and be in
accordance with relevant national and industrial standards.
◎The system must be earthed with equal potential. The earthing device must
meet the requirements of both anti-interference and electric safety, and mustn`t
connect to, or mix with the zero line of any strong power grid. When the system
adopts the earth connection alone, the impedance should be no more than 4Ω,and
section surface should not excess 25mm2.
