4B. LIGHTNING PROOFING AND SURGE PROTECTION
This PTZ adopts TVS lighting protection technology. It can
effectively prevent damages from various pulse signals below
6000W, such as sudden lighting and surge. Necessary precaution
measures should be taken in accordance to local guidelines when
installing the speed dome in an outdoor environment.
●
The signal transmission cable and high-voltage device (or
high-voltage cable) should be at least 50 meters apart.
●
If possible, route cables through a properly grounded and
shielded underground conduit.
●
In areas of strong lightning occurrence or near high sensitive
voltage (such as near high-voltage transformer substation), it is
required to install additional a high-power lightning protection
device or lightning rod.
●
Electrical bonding is recommended. The ground device should
meet anti-jamming requirements and conform to your local
electrical safety code. The ground device should not short
circuit to N (neutral) line of high voltage power grid or mixed
with other wires. When connecting the system to the ground
alone, the grounding resistance should not be more than 4Ω ,
and the earth cable cross-sectional area should be no less than
25 mm². See Figure 5-1.
●
For indoor usage, The yellow and green GND wire or GND
screw of the speed dome should be reliably connected by
several strands of copper wire with no less than 25mm²and
indoor equipotential GND terminal. Please refer to Figure 5-2
for lightning proof installation mode.
