signal that is below 3000W (Eg, Lightning , power surges and etc.) Necessary protections must be
taken to secure the electrical safety outdoors.
1. The distance between signal transmission line and high-voltage equipment or high-voltage cable
is at least 50m.
2. Outdoor wiring should be along the eaves.
3. In the open areas, wires should be buried underground in sealed steel pipes, and the steel pipes
should be one-point grounded. Overhead routing is forbidden.
4. In strong thunderstorm situations or high induction voltage areas (such as areas of high-voltage
transformers), high power lightning protection apparatus and lightning conductor are necessary.
5. The installation, wiring, lightning and grounding protection of this product should be part of the
protection system of the building where this product is installed, and conform to the related
national standards and industry standards.
6. Equipotential grounding should be applied for this product. The grounding equipment must
meet anti-jamming and electric safety requirements, and it’s not allowed to connect to the zero
line of strong power grids. For individual grounding, the resistance should not exceed 4Ω, and
the sectional area should not be less than 25 mm². For detailed grounding instructions, please
