2.2 Grounding and Lightning Protection
In outdoor deployment, the following must be grounded separately: outdoor AP-S800, feeder
lightning protector, lightning protector with Ethernet port and lightning rod. Ensure the
grounding points are well grounded and take anti-oxidation measures against the grounding
points(Grounding cable should be prepared by customers in advance).

Requirements
Lightning rod
In plain areas, the protection angle of the lightning rod should be less than
45 degrees. In mountainous areas or areas lightning occurs frequently, the
protection angle should be less than 30 degrees.
The lightning rod should be high enough so that the access point and
antenna can be protected from lightning strikes.
The protection grounding of the lightning rod should be connected to the
earthing conductor of the server room.

ground (PGND)
If a grounding strip is available, connect the yellow and green grounding
cable of the AP to the grounding strip. The cross-section area of the
grounding cable should be equal to or greater than 6mm² and its length
should not exceed 3 meters.
If no grounding strip is available, bury a piece of angle steel or steel tube at
least 0.5 meter long in the earth to function as the earthing conductor. For a
piece of angle steel, the size should be at least 50 mm × 50 mm × 5 mm; for
a piece of steel tube, it must be zinc-plated and have a wall thickness of at
least 3.5 mm. Weld the yellow and green grounding cable of the AP onto the
angle steel and take anti-erosion measures against the welding joint. The
cross-section area of the grounding cable should be equal to or greater than
6mm² . The grounding cable should be as short as possible and must not be
