General safety precautions
 To ensure human and equipment safety, observe all the safety precautions marked on the equipment and
provided in this document. The ,
the safety precautions that must be followed; they only supplement general safety precautions as a whole.
 When performing operations on Huawei products or equipment, strictly observe related safety precautions and
special safety instructions. The safety precautions in this document are only some that Huawei can predict.

Local rules and regulations
When operating a device, obey local rules and regulations.
Personnel
Installation and maintenance personnel must be trained to perform operations correctly and safely.
Elevated locations
The RTN 980L is usually installed in an elevated location, such as on the roof of a building. Adhere to the following
guidelines for installations in elevated locations:

Installation personnel must have the proper training and qualifications, and meet health requirements.

Installation personnel must wear helmets and safety belts and should work in pairs or teams.

Do not work in high places during thunderstorms, blizzards, gales, or other extreme weather conditions. When
working outdoors, installation personnel must wear clothes and gloves appropriate to the weather conditions,
and anti-slip footwear.

Hoisting tools should be tested before use.

All installation personnel and visitors onsite must wear helmets.
Hoisting heavy objects
 Before hoisting heavy objects, clear the area to avoid hurting anyone
nearby.
 Before hoisting heavy objects, ensure that the hoisting tools are complete
and in good condition.
 Before hoisting heavy objects, ensure that the hoisting tools are fixed to a
secure object or wall with good weight-bearing capacity.
 Ensure that the angle between the two lifting slings is less than or equal to
90 degrees during the hoisting, as shown in the figure.

Max 90°
Devices and installation components
When operating devices and installation components, wear clean gloves.
Avoid direct contact with devices and installation components with bare
hands or dirty gloves.
Device safety
 Before operating a device, check the electrical connection of the device to ensure that the device is securely
grounded.
 Electrostatics produced by human bodies may damage electrostatic-sensitive components on boards, for
example, a large-scale integration (LSI). Therefore, take proper safety measures, such as wearing an
electrostatic discharge (ESD) wrist strap or ESD gloves, to avoid damage to the components when
operating the boards.
 When operating storage batteries, take steps to prevent battery short circuits and electrolyte overflow or
leakage. Electrolyte overflow may corrode metal parts and boards, and ultimately cause equipment rust or
board short circuits.
Corrosion
Anti-corrosion measures are required if an RTN 980L is installed in a location that is prone to corrosion. Contact
your local Huawei office for details. A location is prone to corrosion if it is:
 Within 3.7 km (12139 ft ) of an ocean or a salt water lake.
 Within 3 km ( 9843 ft ) of a heavy pollution source, such as a smelting factory or coal mine.
 Within 2 km ( 6562 ft ) of a medium pollution source, such as a chemical, rubber, or electroplating plant.
 Within 1 km ( 3281 ft ) of a light pollution source, such as a food or leather processing plant or industrial
boiler.
Microwave
High-power radio frequency signals are harmful. Avoid exposure to transmissions from the antennas of
microwave equipment that has the radiation warning symbol
maintenance on an antenna located on a tower that has multiple antennas, be careful not to exposure yourself
to radiation from the other antennas.
IF Cable
Before installing or removing an IF cable, turn off power switch.
