APPENDIX
Lighting protection and Anti-surge
This product uses the gas discharge tube of TVS diode and protection
circuit, can effectively prevent the 3.0 kV following transient lightning and
surge lamp all types of pulse signal to the damage of equipment. But, for outdoor
installation according to the actual situation on the premise of guarantee the
electrical safety to do the necessary protective measures:
● Signal transmission line must be with the high voltage equipment goods
between high voltage cable to keep a distance of at least 50 meters
● Choose as far as possible outside wiring along the roof line
● For open field must adopt sealing pipe buried wiring way, and the steel pipe
by one-point earthing, absolutely forbidden by wiring overhead way
● In strong thunderstorms or high induction voltage region (e.g., high voltage
transformer substation), must be taken to add extra high power lightning pro
tection equipment and installation of lightning rod and other measures
● Lightning protection and grounding design of outdoor installation and
wiring must be combined with the construction of lightning protection
requirements into consideration, and conform to the requirements of relevant
national standards and industry standards.
● The system must be equipotential grounding. Grounding device must meet
the system anti-interference and electrical safety requirements, and shall not be
short term or mixed with strong power grid zero line. System separate
grounding, grounding resistance is not greater than 4Ω.
