6 Appendix Ⅰ Lightning Protection and Surge Protection

This series speed dome adopts TVS lighting protection technology. It can effectively prevent damages

from various pulse signals below 4000V, such as sudden lighting and surge. While maintaining your

local electrical safety code, you still need to take necessary precaution measures when installing the

speed dome in the outdoor environment.

 The distance between the signal transmission cable and high-voltage device (or high-voltage cable)

shall be at least 50 meters.

 Outdoor cable layout shall go under the penthouse if possible.
 For vast land, please use sealing steel tube under the land to implement cable layout and connects

one point to the earth. Open floor cable layout is forbidden.

 In area of strong thunderstorm hit or near high sensitive voltage (such as near high-voltage

transformer substation), you need to install additional high-power thunder protection device or

lightning rod.

 The thunder protection and earth of the outdoor device and cable shall be considered in the building

whole thunder protection and conform to your local national or industry standard.



System shall adopt equal-potential wiring. The earth device shall meet anti-jamming and at the

same time conforms to your local electrical safety code. The earth device shall not short circuit to N

(neutral) line of high voltage power grid or mixed with other wires. When connect the system to the

earth alone, the earth resistance shall not be more than 4Ω and earth cable cross-sectional area

shall below 25 mm2. See Figure 6-1.
