Protect eyes during drilling as dust or flying debris may damage eyes.
à
Clean any debris in time after drilling.
à
l Lightning
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.
l
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.
l
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.
l 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.
l
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.
l
Modules should only contact materials such as an antistatic bag. Keep modules in
antistatic bags during storage and transportation.
l
Discharge static electricity of the test device before use, that is, ground the test device
first.
l
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.
