2 Preparing for Installation
Note
To avoid personal injury and device damage, carefully read the safety precautions
before you install the device.
The following safety precautions may not cover all possible dangers.
2.1 Grounding and Lightning Protection Requirements
Ensure that both the power-receiving end and the power-supplying end are well-
grounded.
The grounding cable is shorter than 30 m (98.43 ft), and use a 40 mm (1.57 in.) x 4 mm
(0.16 in.) or 50 mm (1.97 in.) x 5 mm (0.20 in.) hot-dip galvanized steel flat bar as the
grounding bar.
When the connection cable between the main grounding conductor and local
equipotential earthing terminal board (LEB) on each floor is short, use a stranded
copper wire with a sectional area not less than 1.318 mm2 (16 AWG) for the
connection cable.
Use a shielded network cable if possible, ensure that the devices connected to both
ends of the shielded network cable are reliably grounded, and make sure that the
sheath of the shielded network cable is also grounded if possible. If no shielded
network cable is available, wire the network cable through a steel pipe and bury the
steel pipe for lead-in, and properly ground both ends of the steel pipe.
No additional lightning protector is required as a high-profile lightning protector is
built in the RG-AP680(CD), and the power port support 6 kV lightning protection. If a
lightning protector of a higher profile is available, configure the lightning protector as
required. Before the configuration, connect the lightning protector to the grounding
cable.
Use a power cord with the protective earthing (PE) connector to ground the AC power
supply. Ensure that the PE connector is properly grounded, with a ground resistance
less than 5 ohms. Do not use a two-wire power cable with only the live (L) wire and
naught (N) wire. Do not connect the N wire to the protection grounding cable of other
communication devices, and ensure that the L wire and N wire are properly

Hardware Installation and Reference Guide Preparing for

connected.
Ensure that the ground resistance is less than 5 ohms. In areas with high soil
resistivity, reduce the soil resistivity by measures such as spreading resistivity
reduction mixture around the grounding conductor.
2.2 Installation Site Requirements
Do not expose the AP to high temperature, dusts, or harmful gases. Do not install the AP
in an inflammable or explosive environment. Keep the AP away from EMI sources such as
large radar stations, radio stations, and substations. Do not subject the AP to unstable
voltage, vibration, and strong noises. The installation site should be dry. You are not
advised to install the AP in a place near the sea. Keep the device at least 500 m (1640.42
in.) away from the sea and do not face it towards the sea breeze. The installation site
should be free from water flooding, seepage, dripping, or condensation. The installation
site should be selected according to network planning, communications equipment
features, and considerations such as climate, hydrology, geology, earthquake, electrical
power, and transportation.

2.2.2 Installation Methods
The RG-AP680(CD) can be mounted on a wall or pole.
2.2.3 Waterproof Requirements
Cap unused ports using dust caps to ensure waterproof.

Figure 2-1Dust Cap
Connect the network cable, optical fiber jumper, and DC power cord to the AP after they
pass through the corresponding waterproof plugs to ensure waterproof. For details, see
3.4 Installing the Access Point.
2.2.4 EMI
All interference sources (from outside or inside of the device or application system) affect
the device by capacitive coupling, inductive coupling, or electromagnetic waves.
Electromagnetic interference (EMI) occurs due to electromagnetic radiation or
conduction, depending on the transmission path.
Radiation interference occurs when energy (usually radio frequency energy) is emitted
from a device and propagated through space to disrupt other devices. The interference
source can be part of disrupted system or a fully electrically isolated unit. Conduction
interference occurs when interference is transferred from one unit to another through
cables, which are usually electromagnetic wires or signal cables connected between the
source and the devices experiencing interference. Conduction interference often affects
the power supply of the device. It is eliminated by using filters. Radiation interference
can influence the path of any signal from the device and is difficult to shield.
Take effective measures against interference from the power grid.
Keep the AP far away from the grounding or lightning protection devices for power
equipment.
Keep the AP away from high-power radio stations, radar stations, and high-frequency
high-current devices.
Take electrostatic shielding measures.

2.3 Precautions for Fiber-Optic Cable Connection
Before connecting fiber-optic cables, make sure the model of the optical connector and
fiber type match the optical port. The transmit port on the local device should be
connected to the receive port on the peer device and vice versa.

The RG-AP680(CD) is not delivered with a tool kit. The tool kit is customer-supplied.
2.5 Checking Before Installtion
Note
Please check your goods carefully against the package contents in this document. If you
have any questions, please contact the supplier or agent.

Note
Before installing the AP, make sure you have carefully read the requirements described
in Chapter 2.
3.1 Installation Flowchart
3.2 Before You Begin
Carefully plan and arrange the installation location, networking mode, power supply, and
cabling before installing the device.
Confirm the following requirements before installation:
The installation location meets the temperature and humidity requirements of the

Hardware Installation and Reference Guide Installing the Access Point
13
device.
The power supply and required current are available in the installation location.
The network cables have been deployed in the installation location.
3.3 Precautions
The RG-AP680(CD) can be mounted on a wall or a pole with a diameter ranging from 50
mm to 140 mm (1.97 in. to 5.51 in.). Use the 304 stainless steel hose clamp delivered with
the AP. If the diameter of the pole is out of this range, purchase the SUS304 hose clamp
with a proper size for installation. The thickness of the hose clamp should be at least 2.5
mm (0.10 in.). Otherwise, the AP could fall down and cause injuries. The installation site
should be determined by the technical personnel who conducts a site survey.
To ensure the normal operation of the AP and lengthen the service life of the AP, observe
the following precautions before installing the AP.
Before connecting the power supply, make sure the external power supply matches
the power module inside the AP.
Before connecting the power cord, make sure the power switch is in the OFF position.
When connecting a wire to a grounding stud, make sure their colors are the same.
Make sure the power supply is properly connected.
3.4 Installing the Access Point
(1) Use four M5 screws to secure the AP to the mounting plate.
