Installation Guide

Grounding Protection
It is essential to properly ground all equipment to prevent the A3-Ei from
the electrical damage and possible electric hazer due to non-proper
power grounding. Failure to do so may result in equipment damage,
injury or death.
Product warranty does not cover damage resulting in
part or in whole from improper grounding
. An external grounding wire
must be installed, especially when A3-Ei is deployed on a non-metal
pole or the metal pole is not properly grounded. Please consult your
location’s building and electrical codes and follow them, or consult
standards such as National Electric Code.
Use a
10 AWG
grounding wire to connect to the ground connector of
the A3-Ei by screw driver. Secure the grounding screw tight and the
strap connects to the ground.
It is recommended that the A3-Ei Dual-band 3x3 802.11ac Wi-Fi Access
Point should be installed with lightning rod to avoid any potential
electrical damage and to be connected with the ground node to the
existing ground. Proper grounding will always be the safety
consideration for the A3-Ei Dual-band 3x3 802.11ac Wi-Fi Access Point.
Note: Grounding kits are not provided in the package

Surge Protection
Type of Ethernet cable in outdoor deployment is critical. The Ethernet
cable should be either CAT 5e or CAT 6, outdoor rated, and shielded.
Specifically, the following types of Ethernet cable should be used for
outdoor installation:
screened fully shielded twisted pair (sFTP) cable,
foiled twisted pair (FTP) cable, or shielded twisted pair (STP) cable
.
UTP Ethernet cable and/or unshielded RJ-45 jack
are not
recommended in outdoor deployment due to increasing
electromagnetic noise level. Furthermore, using shielded Ethernet
cable with unshielded RJ45 jack between the A3-Ei and PoE injector is
not recommended. Improperly grounded STP Ethernet cable acts as a
magnet for static surges presented in the environment. Since the
charges discharged improperly, it couples with the data lines or power
lines of the PoE cable. As a result, the coupling high voltages which
presents on the PoE cable may damage the access point. Therefore, it
