Hardware Installation and Reference Guide Preparing for Installation
2 Preparing for Installation
To prevent device damage and physical injury, please read carefully the safety recommendations described in this
chapter.
Recommendations do not cover all possible hazardous situations.
2.1 Grounding and Lightning Protection
Ensure that both the power-receiving end and the power-supplying end are well-grounded.
Keep the grounding connection within 30 m, and use a 40mm x 4mm or 50mm x 5mm ground bar of hot-dip
zinc-coated flat steel sheet.
When the connection cable between the main grounding conductor and local equipotential earthing terminal board
(LEB) on each floor is shorter than 2 meters, 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 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-EAP602, and the
power port support 6kV lightning protection. If a lightning protector of a higher profile is available, configure the
lightning protector optionally. Before the configuration, connect the lightning protector to the ground cable.
Use a power cable with the PE end to ground the power supply (AC). Ensure that the PE end 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 ground cable of other communication devices, and ensure that
the L wire and N wire are properly connected.
Ensure that the ground resistance is less than 5 ohms. In areas with high soil resistivity, reduce the soil resistivity via
measures such as spreading resistivity reduction mixture around the grounding conductor.
2.2 Preparing the Installation Site
Do not expose the AP to high temperature, dust, or harmful gases.
Do not install the AP in an area prone to fire or explosions.
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 noises.
Keep the AP at least 500 meters away from the ocean and do not face it towards the sea breeze.
The installation site should be protected from water and 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, electric power, and transportation.
