Chapter 1 Safety Instruction
� 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 damag-
ing 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. Resis-
tance 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 modules with any object that
easily generates static electricity. For example, friction of pack-
age 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 con-
tact a human body or the ground.
� Modules should only contact materials such as antistatic bag.
Keep modules in antistatic bags during storage and transporta-
tion.
� 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 dis-
assembling heavy equipment, or moving and replacing equip-
ment.
� The installation personnel 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 pre-
vent any mishap.
Unplugging/Plug-
ging 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 cir-
cuit 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.
