Danger:
High voltage and AC operations, or
operations on a steel tower and a mast on a thunderstorm day are prohibited.
On a thunderstorm
day,the electromagnetic field generated in the thunderstorm area may cause
damage to electronic parts. In order to prevent the equipment from being
damaged by lightning, proper grounding is required.
Caution:
The electrostatic (static electricity)
generated by human body may damage the electrostatic-sensitive components on
the circuit board, such as large-scale integrated circuit (LIC).
In the case of
human body moving, clothes friction, friction between shoes and ground, holding
ordinary plastic in hand, the human body will generate a static electromagnetic
field that will remain with the human body for a long time.
Before touching the
equipment, hand-holding, circuit boards, or ASICs, a grounded electrostatic
discharge (ESD) wrist strap should be worn to prevent the sensitive components
from being damage by the electrostatic in human body.

electrostatic protection wrist strap
Warning:
For the safety of continuous operation,
please replace the fuse with that of the same type and rating, if necessary.
The laser hazard
level of this equipment is Class 1.
Warning:
When performing installation and
maintenance operations of optical fibers, you should not stand close to, or
look into the optical fiber outlet directly with unaided eyes.
Laser transceiver/
transmitter are used in optical transmission system and associated test
instruments. The wavelength of the laser is above 780nm, and lower than 1600nm.
Because the laser being transmitted through the optical fiber produces a small
beam of light, it has very high power density and is invisible to human eyes.
When a beam of light enters the eye, retinal may be burned.
The damage
mechanism at the wavelengths used in telecommunications is thermal in origin
i.e., damage caused by heating. Therefore, a specific amount of energy is
required for a definite time to heat an area of retinal tissue.
Lasers used in
lightwave systems have a larger beam divergence, typically 10 to 20 degrees.
Inadvertently viewing an un-terminated fiber or damaged fiber with the unaided
eye at distances greater than 150 mm (6 inches) will normally not cause eye
injury. However, damage may occur if an optical instrument such as a
microscope, magnifying glass or eye loupe is used to view the energized fiber
end.
In its normal
operating mode, a lightwave system is totally enclosed and presents no risk of
eye injury. Additional safety is achieved by the implementation of an Automatic
Laser Shut-down (ALS) of the system. The ALS, however, can be applied for
bi-directional transmission only. If the receiver side does not detect the laser
from the transmission side, it will give the transmission side a signal, so the
ALS will shutdown the laser emission in less than 100ms.
Read the following
guidelines to avoid laser radiation:
l
Read the relevant instructions before
installation, operation and maintenance of the equipment. Ignoring the
instructions can cause in exposure to dangerous laser radiation.
l
An eye-protective glasses are recommended when
you are handling lasers or fibers.
l
All the operation shall be performed by
authorized personnel who satisfactorily completed an approved training course.
l
Make sure that the optical source is switched
off before disconnecting optical fiber connectors.
l
Before opening the front door of an optical
transmission system, always take care that you are not exposed to laser
radiation.
l
Never look into the end of an exposed fiber or
an open connector as long as you are not sure whether the optical source is
switched on or off.
l
Please use optical power meter to check that the
optical source is switched off by measuring the optical power.
l
Never use optical instrument such as a
microscope, magnifying glass or eye loupe to view the optical connector or
fiber..
Read the
instructions before handling fibers.
l
Cutting and splicing fibers must be performed by
trained personnel only.
l
Before cutting or splicing the fibers, always
verify the fiber is disconnected from the optical source. After disconnect the
fiber, all the optical connectors must be protected by a protecting cap.
Warning:
When working at heights, be cautious to
prevent objects from falling.
High-altitude work
should comply with the following requirements:
l
High-altitude operators must be trained.
l
Operating machines and tools should be carried
and handled safely to avoid falling.
l
Take safety protection measures like wearing
helmet and safety belt.
l
In cold areas, heat-retaining clothes should be
worn before high-altitude operation.
l
All lifting appliances should be checked before
high-altitude operation.
Before using the
ladder, first check if the ladder is damaged. Make sure the ladder is safe for
use. Overweight on the ladder is strictly prohibited.
The slant of the
ladder is 75° at best. The slant can be measured with Angle Square or with arms.
When a ladder is used, the wider end of the ladder should be placed against the
ground or protective measures should be taken on the base part of the ladder
for the purpose of skid resistance. Place the ladder against a stable ground.
When climbing the
ladder, one’s center of gravity should not deviate from the ladder edge.
To lessen the danger and ensure safety, three parts of the body should be on
the ladder. When climbing the ladder, the upper limit of the height should not
exceed the highest four steps. If one is about to climb to the top, the length
of the ladder should be 1 meter higher than the eave
Warning:
Access to the areas under the gib arm and
the goods in suspension is strictly prohibited when hoisting weight.
l
The weight hoisting operators should undergo
related training and be qualified. The weight hoisting tools should be checked
and be complete. Make sure that only when the weight hoisting tools are firmly
fixed onto the weight-bearing object or the main wall can weight-hoisting
operations be undertaken. Use concise command to avoid mis-operation.
l
The slant of the cabinet-top bearing cable for
hoisting should not be greater than 90° to prevent the cable from breaking.
