Safety Precautions
Thunderstorms
Do not work with electrical current or work in elevated or exposed locations during a thunderstorm.
Extreme weather conditions
OAU 2F is usually installed outdoors. If weather conditions are extreme during an installation, personnel
should follow the related local guidelines and regulations to safeguard personal health and safety.
Elevated locations
OAU 2F is usually installed in an elevated location, for example, on the rooftop of a building. For installation
in elevated locations, installation personnel must:
Have the proper training and qualifications, and meet health requirements.
Wear helmets, safety belts, and anti-slip footwear.
Wear clothing and gloves appropriate to weather conditions.
Work in teams of two or more.
Test hoisting tools before use.
Avoid installation during extreme weather conditions, such as during thunderstorms, blizzards, or gales.
In addition, all site visitors must wear helmets.
Microwave
High-power radio frequency signals are harmful. Avoid exposure to transmission from the antennas of
microwave equipment that has the radiation warning symbol (
performing maintenance on an antenna located on a tower that has multiple antennas, avoid exposure to
radiation from other antennas.

Handling of OAU 2F or mounting kits
Wear clean gloves when handling the OAU 2F or mounting kits.
Lasers
Do not look into an optical port without eye protection.
Corrosion
Anti-corrosion measures are required if an OAU 2F is installed in a location that is prone to corrosion. Contact the
local Huawei office for details. A location is prone to corrosion if it is:
Within 3.7 km of an ocean or a salt water lake
Within 3 km of a heavy pollution source, such as a smelting factory or coal mine
Within 2 km of a medium pollution source, such as a chemical, rubber, or electroplating plant
Within 1 km of a light pollution source, such as a food/leather processing plant or heating boiler
Local rules and regulations
If local rules and regulations require that anti-corrosion measures must be taken for ground connections, comply with
local rules and regulations.
Unpacking
After unpacking an OAU 2F, power it on within 24 hours.
Do not power off an OAU 2F for more than 24 hours during maintenance.
