Safety Precautions
Be sure to read the
Safety Precautions for All Solid State Relays
in the website at the following URL:
http://www.ia.omron.com/.
Format of Warning Indications
Indicates a potentially hazardous situation
which, if not avoided, may result in minor or
moderate injury or in property damage.
Indicates supplementary comments on
what to do or avoid doing, to use the
product safety.
Includes operating precautions to ensure
that the product will operate properly and
that performance and functions will not be
adversely affected.

Correct Use
Precautions for Safe Use
OMRON constantly strives to improve quality and reliability.
The G3PJ, however, use semiconductors, and semiconductors may
commonly malfunction or fail. In particular, it may not be possible to
ensure safety if the G3PJ are used outside the rated ranges.
Therefore, always use the SSRs within the ratings. When using the
G3PJ, always design the system to ensure safety and prevent human
accidents, fires, and social harm in the event of the G3PJ failure.
System design must include measures such as system redundancy,
measures to prevent fires from spreading, and designs to prevent
malfunction.
Meaning of Graphic Symbols for Ensuring Product Safety
Indicates the possibility of electric shock under
specific conditions.
Transport
Do not transport the G3PJ under the following conditions.
Doing so may result in damage, malfunction, or deterioration of
performance characteristics.
• Conditions in which the G3PJ may be subject to water.
• Conditions in which the G3PJ may be subject to high temperature
or high humidity.
• Conditions in which the G3PJ is not packaged.
• Do not drop the G3PJ or subject it to abnormal vibration or shock
during transportation or mounting. Doing so may result in
deterioration of performance, malfunction, or failure.
Indicates the possibility of explosion under specific
conditions.
Indicates the possibility of injuries by high
temperature under specific conditions.
Operating and Storage Environments
CAUTION
Minor electrical shock may occasionally occur.
Do not touch the G3PJ terminal section (i.e., current-
carrying parts) while the power is being supplied.
Also, always attach the cover terminal.
The G3PJ may rupture if short-circuit current flows. As
protection against accidents due to short-circuiting,
be sure to install protective devices, such as fuses
and no-fuse breakers, on the power supply side.
Minor electrical shock may occasionally occur.
Do not touch the main circuit terminals on the G3PJ
immediately after the power supply has been turned
OFF. Shock may result due to the electrical charge
stored in the built-in snubber circuit.
Minor burns may occasionally occur.
Do not touch the G3PJ or the heat sink while the
power is being supplied or immediately after the
power supply has been turned OFF. The G3PJ and
heat sink become extremely hot.
Do not use or store the G3PJ in the following locations. Doing so may
result in damage, malfunction, or deterioration of performance
characteristics.
• Locations subject to rainwater or water splashes.
• Locations subject to exposure to water, oil, or chemicals.
• Locations subject to high temperature or high humidity.
• Do not store in locations subject to ambient storage temperatures
outside the range
−30
to 100°C.
• Locations subject to relative humidity outside the range 35% to
85% or locations in which condensation may occur due to rapid
changes in temperature.
• Locations subject to corrosive gases.
• Locations subject to dust (especially iron dust) or salts.
• Locations subject to direct sunlight.
• Locations subject to shock or vibration.
• Do not allow solvents such as thinners or gasoline to come into
contact with the plastic parts of the G3PJ. A solvent may erase the
markings.
• Do not allow oil to come into contact with the terminal cover on the
G3PJ. The cover may become milky or crack.
Installation and Handling
• Do not block the movement of the air surrounding the G3PJ or heat
sink. Abnormal heating of the G3PJ may result in shorting failures
of the output elements or burn damage.
• Do not use the G3PJ if the heat radiation fins have been bent by
being dropped. Doing so may result in malfunction due to a
reduction in the heat radiation performance.
• Do not handle the G3PJ with oily or dusty (especially iron dust)
hands. Doing so may result in malfunction.
