Chapter 3 Lightning Protection
3.1 Cabling Reasonably
In the actual network environment, you may need cable outdoors and indoors, and
the requirements for cabling outdoors and indoors are different. A reasonable
cabling system can decrease the damage of induced lightning to devices.
Note: It’s not recommended to use Ethernet cables outdoors. When cabling
outdoors, please use a signal lightning arrester.
■Requirements for Cabling Outdoors
■Aerial cabling without safeguard is not allowed.
■It’s not allowed cabling down the building to connect network devices in different
floors.
■Outdoor cables should be buried and paved to the indoor through basement. A
piece of steel wire should be paved underground along the pipe and connected to
the lightning protection terminal of the building for shielding. Before connecting
the cable to the device, install a signal lightning arrester on the corresponding
port.
■When an aerial cable is set up, the cable should be through a metal pipe (15m long
at least) before coming into the building. The two ends of this metal pipe should
be grounded. Before connecting the cable to the device, install a signal lightning
arrester on the corresponding port.
■It’s not necessary to pave STP cables through pipes. The shielded layer of STP
cable should be well grounded. Before connecting the cable to the device, install a
signal lightning arrester on the corresponding port.
■Requirements for Cabling Indoors
When cabling indoors, keep a certain distance away from the devices that may
cause high-frequency interferences, such as down-conductor cable, powerline,
power transformer and electromotor.
■The main cable should be paved in the metal raceway of the access shaft. When
cabling, keep the loop area formed by the cable itself as small as possible.

3.2 Connect to Ground
Connecting the device to ground is to quickly release the lightning over-voltage and
over-current of the device, which is also a necessary measure to protect the body
from electric shock.
In different environments, the device may be grounded differently. The following
will instruct you to connect the device to the ground in two ways, connecting to the
ground via the power supply or connecting to the ground via the grounding terminal.
Please connect the device to ground in the optimum way according to your specific
operation environment.
Note:
For the device without grounding terminal, please refer to the rst way Connecting to
the Ground via the Power Supply only.
■Connecting to the Ground via the Power Supply
If the device is installed in the normal environment, the device can be grounded via
the PE (Protecting Earth) cable of the AC power supply as shown in the following
figure.
Figure 3-1 Connecting to the Ground via Power Supply
Switch (Rear Panel) AC Power Cord (with PE cable)
Note:
■The figure is to illustrate the application and principle. The power plug you get from
the package and the socket in your situation will comply with the regulation in your
country, so they may differ from the figure above.
■If you intend to connect the device to the ground via the PE (Protecting Earth) cable
of AC power cord, please make sure the PE (Protecting Earth) cable in the electrical
outlet is well grounded in advance.
■Connecting to the Ground via the Grounding Terminal
Use the grounding bar
If the device is installed in the Equipment Room, where a grounding bar is available,
you are recommended to connect the device to the grounding bar as shown in the
following figure.

Equipotential Bonding
Equipotential Bonding is the practice of intentionally electrically connecting all
earthed systems to the same grounding grid or connecting the grounding grids of
all the earthed systems together through the ground or overground metal so as
to create an earthed equipotential zone. When lightning occurs, the high voltage
produced by lightning current in all systems will meanwhile exist in their ground
cables, and thus all ground cables have the same electrical potential and basically
eliminate the electric strikes between the systems.
The figure below illustrates how to practice equipotential bonding in a network.
Figure 3-3 Equipotential Bonding
Grounding Terminal Equipotential Bonding Cable
Grounding BarGround Cable
When equipotential bonding, please note that the cable should be copper wrapped
Kelly with its area being 6mm2at least. The shorter cable the better, and use a
grounding bar to establish an equipotential bonding point.
