AC power
grounding
Make sure you use the power cable with a PE
terminal but not the cables with only L and N
wires.
It is strictly prohibited to connect the N wire of
the power cable to the protection ground of
any other communications device, and the L
and N wires must be connected correctly.
Lightning
rod
In a plains area, the protection angle of the
lightning rod should be less than 45 degrees. In
a mountainous area or lightning intensified
area, the protection angle should be less than
30 degrees. The lightning protection ground
(for example, the ground of the lightning rod)
and the protection ground of the equipment
room should be connected to the same
earthing conductor.
Feeder
The antenna support is ready and in
accordance with the design requirement.
A feeder lightning rod is already installed and
grounded according to the design requirement.
Outdoor
lightning
arresters
For outdoor installation, a power lightning
arrester, a feeder lightning arrester and a
network port lightning arrester are required.
The power supply lightning arrester and feeder
lightning arrester are located close to the AP
while the port lightning protector is installed
close to the peer device where the network
cable enters the equipment room, just outside
the equipment room.
Network
cable
For outdoor installation, use a shielded network
cable and ensure that the interconnected
devices are well grounded.
After you have completed the installation preparations, continue with AP installation in
Chapter 3 Installing the on page 15.
