Meaning of Product Safety Symbols
Warning Symbols
The ES1-LW50L-N and ES1-LW100L-N contain a Class 1
laser. Never look at the laser light or allow the laser light to
enter the eye. Do not allow laser light reflected from a mirror
to enter the eye.
Never disassemble the product. Risk of vision
impairment or blindness from laser light leakage if
disassembled.
Minor injury due to electric shock may occasionally occur.
Do not touch the connections such as the temperature
controller while power is being supplied.
Make sure that the product's metal enclosure is not
touching the voltage-applied conductors. For
touching the product's metal enclosure with bare
hands, electrical shock may occur. The product's
metal enclosure and internal circuits, the power
supply, current output, or USB port are not isolated.
Electric shock, fire, or malfunction may occasionally
occur. Do not allow metal objects, conducting wires,
shavings or powder from installation work, water, or
other foreign objects to enter the product.
Do not use the product where subject to flammable or
explosive gas. Otherwise, minor injury from
explosion may occasionally occur.
Never disassemble, modify, or repair the product or
touch any of the internal parts. Minor electric shock,
fire, or malfunction may occasionally occur.
If the output relays are used past their life expectancy,
burning may occasionally occur. Always consider the
application conditions and use the output relays
within their rated load and electrical life expectancy.
When measuring an object at high temperature, keep
the sensor a sufficient distance away from the object
and measure within ambient temperature.
• The setting gauge is flammable. Do not allow flame or
fire near the setting gauge.
• If the object of measurement is at high temperature, do
not use the setting gauge.
• Use the setting gauge only after the temperature of the
object of measurement has cooled to normal
temperature.
WARNING
Indicates a potentially hazardous
situation which, if not avoided, will
result in minor or moderate injury, or
may result in serious injury or death.
Additionally there may be significant
property damage.
CAUTION
Indicates a potentially hazardous
situation which, if not avoided, is
likely to result in minor or moderate
injury or property damage.
Indicates the possibility of the risk of laser beam
exposure
Indicates prohibitions when there is a possibility
of injury, such as from electric shock, as the
result of disassembly
Indicates possibility of electric shock under
specific conditions
Indicates non-specific general prohibitions
Indicates non-specific general cautions,
warnings, and dangers
Indicates the possibility of injury by high
temperature under specific conditions
