Chapter 1 Safety Description
Antistatic Safety Instructions
Caution!
Static electricity produced by human body can damage static-sensitive components on
circuit board, such as large-scale integrated circuits.
Friction caused by human body activities is the root cause of electrostatic charge
accumulation. Static voltage carried by a human body in a dry environment can be
up to 30 kV, and can remain there for a long time. An operator with static electricity
may discharge electricity through a component when he/she touches the conductor
and causing damage.
Wear an antistatic wrist strap (the other end of wrist strap must be well grounded)
before touching the equipment or holding a plug-in board, circuit board, Integrated
Circuit (IC) chip or other devices, to prevent human static electricity from damaging
sensitive components.
The antistatic wrist strap used must be subject to regular check. Do not replace the
cable of an antistatic wrist strap with any other cables.
Do not contact static-sensitive modules with any object that easily generates static
electricity. For example, friction of package bag, transfer box and transfer belt made
from insulation plastic may cause static electricity on components. Discharge of static
electricity may damage components when they contact a human body or the ground.
Modules should only contact materials such as an antistatic bag. Keep modules in
antistatic bags during storage and transportation.
Discharge static electricity of the test device before use, that is, ground the test device
first.
Do not place the module near a strong DC magnetic field, such as the cathode-ray
tube of a monitor. Keep the module at least 10 cm away.
Hoisting Heavy Objects
Warning!
When hoisting heavy objects, ensure that nobody is standing or walking under the hoisted
object.
Ensure the hoister can meet hoisting requirements when disassembling heavy
equipment, or moving and replacing equipment.
The installation personnel must be duly trained and qualified for hoisting operations.
Hoisting tools must be inspected and complete before service.
1-5
SJ-20100722143906-002|02/20/2011(R1.3)
ZTE Proprietary and Confidential
ZXSDR R8860 Installation Manual
Make sure that hoisting tools are fixed firmly on a sufficiently secured object or wall
before the hoisting operation.
Give brief oral instructions during hoisting operations to prevent any mishap.
Unplugging/Plugging a Module
Never plug a module with excessive force, to ensure that the pins on the backplane
do not get deformed.
Plug the module right into the slot and make sure module circuit faces do not contact
each other lest any short circuit may occur.
Keep hands off the module circuit, components, connectors and cable trough when
holding a module.
Rack Mount Safety Instructions
Rack Mount Instructions - The following or similar rack-mount instructions are included
with the installation instructions:
Elevated Operating Ambient - If installed in a closed or multi-unit rack assembly, the
operating ambient temperature of the rack environment may be greater than room
ambient. Therefore, consideration should be given to installing the equipment in an
environment compatible with the maximum ambient temperature (Tma) specified by
the manufacturer.
Reduced Air Flow - Installation of the equipment in a rack should be such that the
amount of air flow required for safe operation of the equipment is not compromised.
Mechanical Loading - Mounting of the equipment in the rack should be such that a
hazardous condition is not achieved due to uneven mechanical loading.
Circuit Overloading - Consideration should be given to the connection of the
equipment to the supply circuit and the effect that overloading of the circuits might
have on overcurrent protection and supply wiring. Appropriate consideration of
equipment nameplate ratings should be used when addressing this concern.
Reliable Earthing - Reliable earthing of rack-mounted equipment should be
maintained. Particular attention should be given to supply connections other than
direct connections to the branch circuit (e.g. use of power strips).
Other Safety Instructions
Note:
Do not perform maintenance or debugging independently, unless a qualified person is
present.
Perform an airtight test before RRU delivery, and prohibit disassembling the RRU on
site.

1. Clean the connectors and the part of the cable surfaces that is to be sealed.
2. To simplify removal of the 1+3+3 waterproof material as a whole in future maintenance,
wrap a layer of tape with the strength of unwrapping the tape from bottom to top,
overlapping each turn 50 percent, as shown in Figure 4-3.
Figure 4-3 Wrapping a Layer of Tape
3. Unwrap the plaster, and peel the paper backing. Then, extend the plaster to one to
two times the original size, face the sticky side (from which side the paper backing is
removed) to the connector or cable, and then apply three layers of plaster, from bottom
to top, from top to bottom, and from bottom to top. Overlap each turn 50 percent. Use
your fingers to mold the plaster so that the plaster between three layers is well bond,
as shown in Figure 4-4.

Note
1. Wrap the tape with the strength of unwrapping the tape (that is, the strength of naturally
unwrapping the tape). The tape should not be extended.
2. Extend the plaster to one to two times the original size while wrapping.
3. Overlap each turn of the tape and plaster at least 50 percent.
4. The directions of the plaster and tape should be the same. The direction must be good
for fastening the screw. This prevents shrink of the extended plaster from loosening
the connector.
5. On the two ends, overlap the plaster and tape for one turn (when changing the
wrapping direction).
6. After wrapping, use your fingers to mold the plaster so that the plaster between the
layers is well bond.
7. The wrapping length of the tape must be (about 10 mm) longer than that of plaster,
especially on the cable end. Ensure that the plaster is over the tape so that the 1+3+3
waterproof material can be removed as a whole in future maintenance with cables
undamaged.
8. After wrapping, cut the plaster and tape with the scissors or knife. Do not break the
plaster or tape directly with your hands.
9. Bind the cable fasteners to the tape (under which there are plaster layers) to prevent
removal of the tape or shrink of the plaster if the cable fasteners are loosened.
