could result in death or serious injury.
Caution:
Indicates a potentially hazardous situation which, if not avoided,
could result in serious injuries, equipment damages or interruption
of part services.
Safety Instructions
This section describes the safety instructions related to electrical
safety, antistatic, heavy objects and boards.
Electrical Safety
Instructions
The following are the electrical safety instructions about tools, high
voltage, power cables, holes and lightning:
�
Tools
Use special tools rather than common tools for high-voltage
and AC operations.
�
High Voltage
Danger:
High voltage is hazardous. Direct or indirect contact with high
voltage or main supply using a wet object could result in death.
�
�
�
�
�
Strictly follow local safety rules to install AC power equipments.
Installation staff must be qualified for performing high-voltage and AC operations.
Do not wear any watch, hand chain, bracelet, ring or any
other conductive object during such operations.
Prevent moisture from accumulating on the equipment during operations in a damp environment.
Power Cable
Confidential and Proprietary Information of ZTE CORPORATION
ZXSDR R8860 Installation Manual
Warning:
Never install or uninstall power cables while they are live. Otherwise, the power cable, when contacting a conductor, may result in sparks or electric arc causing a fire or even damage to
eyes.
�
�
�
Make sure to shut off power supply before installing or disconnecting a power cable.
Before connecting the power cable, make sure that the connecting cable and its label is appropriate for the actual installation requirements.
Drilling Holes
Warning:
It is not allowed to drill cabinet holes without permission.
�
�
�
�
Unqualified drilling could damage wiring and cables inside
the cabinet. Additionally, metal pieces inside the cabinet created by the drilling could result in a shorted circuit
board. Use insulation protection gloves and move cables
within the cabinet away first when drilling is necessary on
a cabinet.
Protect eyes during drilling as dust or flying debris may
damage eyes.
Clean any debris in time after drilling.
Lightning
Danger:
Do not perform high-voltage, AC, iron tower or mast operations
in a thunderstorm.
Thunderstorms would give rise to a strong electromagnetic
field in the atmosphere. Therefore, the equipment must be
grounded and protected in time against lightning strikes.
Antistatic Safety
Instructions
Electrostatic:
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 in there for a long time. An operator with static
Confidential and Proprietary Information of ZTE CORPORATION
Chapter 1 Saftey Description
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.
�
A resistor over 1 MΩ should be connected in series on the cable
between the antistatic wrist strap and the grounding point, to
protect the operator against accidental electric shock. Resistance over 1 MΩ is low enough to discharge static voltage.
�
The antistatic wrist strap used must be subject to regular
check. Do not replace the cable of an antistatic wrist strap
with any other cable.
�
Do not contact static-sensitive boards 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.
�
Board should only contact materials such as antistatic bag.
Keep boards 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 board near a strong DC magnetic field, such
as the cathode-ray tube of a monitor. Keep the board at least
10 cm away.
Hoisting Heavy
Objects
Warning:
When hoisting heavy objects, ensure that nobody is standing or
walking under the hoisted object.
Unplugging/Plugging a Board
�
Ensure the hoister can meet hoisting requirements when disassembling heavy equipment, or moving and replacing equipment.
�
The operator must be duly trained and qualified for hoisting
operations.
�
Hoisting tools must be inspected and complete before service.
�
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.
�
Never plug a board with excessive force, to ensure that the
pins on the backplane do not get deformed.
�
Plug the board right into the slot and make sure board circuit
faces do not contact each other lest any short circuit may occur.
�
Keep hands off the board circuit, components, connectors and
cable trough when holding a board.
