Definition of Precautionary Information
Indicates a potentially hazardous situation which,
if not avoided, will result in minor or moderate
WARNING
injury, or may result in serious injury or death.
Additionally there may be significant property
damage.
A potentially hazardous situation by misuse, may
CAUTION
result in property damage only accident.
Minor hazard by electric shock may occasionally occur.
Do not touch the G3RV's terminal (Charging part) while
the power supply turned on.
The G3RV may occasionally rupture in case of a short
circuit.
To protect against short-circuit accident, install a
protective device, such as a quick-burning fuse or a
circuit breaker or the like, on the power supply.
Minor hazard by electric shock may occasionally occur.
Do not touch the G3RV's main circuit terminals
immediately after the power is turned OFF.
The internal snubber circuit is charged.

Minor hazard by burns may occasionally occur.
Do not touch the G3RV or the heat sink either while the
power supply is ON, or immediately after the power is
turned OFF.
The G3RV and the heat sink will be hot.
Precautions for Safe Use
● Shipping
When shipping the G3RV, be sure to avoid the following:
• Conditions where the G3RV is exposed to water.
• High ambient temperatures and humidity.
• Inadequate packaging
Failure to avoid these conditions while shipping G3RV will lead to
damage, malfunction, or deterioration.
● Operating and Storage Locations
Do not use or store the G3RV in the locations listed below. Failure
to do so may result in damage, malfunction, or deterioration of
performance characteristics.
• Locations subject to rain or water drops.
• Locations subject to exposure to water, or oil, or chemicals.
• Locations subject to high temperatures or high humidity.
• Locations subject to ambient temperatures outside the range
from -30 to +100 centigrade.
• Locations subject to relative humidity outside the range 45% to
85%.
• Locations subject to corrosive or flammable gases.
• Locations subject to dust (especially iron dust) or salts.
• Locations subject to barrier.
• Locations subject to static electricity or other forms of noise.
• Locations subject to strong electromagnetic fields.
• Locations subject to possible exposure to radioactivity.
CAUTION
● Handling
• Be sure to provide adequate air flow to G3RV. Failure to do so
can cause the G3RV to overheat leading to short circuit and
burning.
• Do not install G3RV Relay with bent terminals into the socket.
Doing so could lead to poor electrical connection and hazardous
conditions.
• Be sure to mount G3RV's with clean hands. Performing
mounting with oil stained hands or coated with metal powder
could result in hazardous outcomes.
● Mounting
• Be sure to mount the G3RV in the specified orientation.
Mounting the G3RV in a different orientation could lead to
abnormal heat generation causing output elements to short
leading to burning.
• G3RV's are SSR's and generate heat. Be sure to control
ambient temperature in setting where G3RV is used. If mounted
in an enclosed space, install a fan to insure G3RV is properly
ventilated.
• Be sure that the G3RV clicks into place when mounting it to DIN
Track. The G3RV may fall if it is not mounted correctly.
● Wiring
• Use a wire an adequate size for current to be applied. Abnormal
heating of wire may cause burning.
• Do not use any wires with damaged sheaths. These may cause
electric shock.
• Confirm that wiring to G3RV Socket is not used in pipe or duct
for high voltage power supply. Using a wire in pipe or duct
connected to high voltage power supply will generate induction
causing malfunction or damage.
• Be sure to conduct wiring with the power supply turned OFF.
Touching the terminals when they are charged may occasionally
result in minor electric shock.
● Using
• Select a load within the rated range. Inappropriate load may
cause misoperation, trouble or burning.
• Select the power supply within the rated frequency range.
Inappropriate power frequency may cause misoperation, trouble
or burning.
Precautions for Correct Use
● G3RV uses electronics parts inside, so that any dropping,
vibration, and physical shock beyond the standard level should be
prevented. Failure to do so may result in damage, malfunction, or
deterioration of performance characteristics.
● Be sure to use tightening torque of 0.4 N·m for screw terminal
G3RV. Failure to do so could result in short circuit failure and
burning.
● Be sure to use proper voltage/current to G3RV input and output
terminals. Failure to do so could result in short circuit failure and
burning.
