Safety Precautions
3. Wire the G3NA and tighten screws correctly, observing the follow-
! Caution
Touching the charged section may occasionally cause
minor electric shock. Do not touch the G3NA terminal sec-
tion (the charged section) when the power supply is ON.
Be sure to attach the cover before use.
! Caution
The G3NA and heat sink will be hot and may occasionally
cause minor burns. Do not touch the G3NA or the heat
sink either while the power supply is ON, or immediately
after the power is turned OFF.
ing precautions
Heat generated by a terminal error may occasionally result in fire
damage. Do not operate if the screws on the output terminal are
loose.
? Abnormal heat generated by wires may occasionally result in
fire damage. Use wires suitable for the load current.
? Abnormal heat generated by terminals may occasionally result
in fire damage. Do not operate if the screws on the output termi-
nal are loose.
Tightening Torque
! Caution
The internal snubber circuit is charged and may occasion-
ally cause minor electric shock. Do not touch the G3NA’s
main circuit terminals immediately after the power is
turned OFF.

! Caution
Be sure to conduct wiring with the power supply turned
OFF, and always attach the terminal cover after complet-
ing wiring. Touching the terminals when they are charged
may occasionally result in minor electric shock.
! Caution
Do not apply a short-circuit to the load side of the G3NA.
The G3NA may rupture. To protect against short-circuit
accidents, install a protective device, such as a quick-
burning fuse, on the power supply line.
■ Precautions for Safe Use
Although OMRON continuously strives to improve the quality and
reliability of our relays, the G3NA contains semiconductors, which
are generally prone to occasional malfunction and failure.
Maintaining safety is particularly difficult if a relay is used outside of
its ratings. Always use the G3NA within the rated values. When using
the G3NA, always design the system to ensure safety and prevent
human accidents, fires, and social damage even in the event of
G3NA failure, including system redundancy, measures to prevent
fires from spreading, and designs to prevent malfunction.
1. G3NA malfunction or fire damage may occasionally occur. Do not
apply excessive voltage or current to the G3NA terminals.
2. Heat Dissipation
? Do not obstruct the airflow to the G3NA or heat sink. Doing so
may cause the output element to short, or cause fire damage.
? Be sure to prevent the ambient temperature from rising due to
the heat radiation of the G3NA. If the G3NA is mounted inside a
panel, install a fan so that the interior of the panel is fully venti-
lated.
? Mount the G3NA in the specified orientation. If the G3NA is
mounted in any other orientation, abnormal heat generation
may cause output elements to short or may cause burning.
? Do not use the G3NA if the heat sink fins are bent, e.g., as the
result of dropping the G3NA. Heat dissipation characteristics will
be reduced, possibly causing G3NA failure.
? Apply a thin layer of Momentive Performance Material’s YG6260
or Shin-Etsu Chemical’s G747, or a similar product to the heat
sink before mounting.
? If a material with high thermal resistance, such as wood, is
used, heat generated by the G3NA may occasionally cause fire
or burning. When installing the G3NA directly into a control
panel so that the panel can be used as a heat sink, use a panel
material with low thermal resistance, such as aluminum or steel.
? Use the specified heat sink or one with equivalent or better char-
acteristics.
? Abnormal heat generated by terminals may occasionally result
in fire damage. When tightening terminal screws, be sure that
no non-conductive foreign matter is caught in screw.
? For GN3A Relays of 40 A or higher, use crimp terminals of an
appropriate size for the wire diameter for M5 terminals.
? Do not use any wires with damaged sheaths. These may cause
electric shock or leakage.
? Do not place wiring in the same conduit or duct as high-voltage
lines. Induction may cause malfunction or damage.
? Use wires of an appropriate length, otherwise malfunction and
damage may result due to induction.
? Mount the DIN Track securely. Otherwise, the DIN Track may
fall.
? Be sure that the G3NA clicks into place when mounting it to DIN
Track. The G3NA may fall if it is not mounted correctly.
? Do not mount the G3NA when your hands are oily or dirty, e.g.,
with metal powder. These may cause G3NA failure.
? Tighten the G3NA screws securely. Tightening torque: 0.78 to
0.98 N ? m
? Tighten the heat sink screws securely. Tightening torque: 0.98
to 1.47 N ? m
4. Preventing Overheating
When using the High-capacity Heat Sink (Y92B-P250NF), always
use a thermostat or other method to protect from overheating in
the event that the fan stops.
5. Do Not Touch Fan Blades
When the fan is operating, do not touch the fan blades with any
part of your body or allow foreign matter to come into contact with
the blades. Always attach the enclosed finger guard when using
the G3NA.
6. Operating Conditions
? Only use the G3NA with loads that are within the rated values.
Using the G3NA with loads outside the rated values may result
in malfunction, damage, or burning.
? Use a power supply within the rated frequency range. Using a
power supply outside the rated frequency range may result in
malfunction, damage, or burning.
7. Do not transport the G3NA under the following conditions. Failure
or malfunction may occur.
? Conditions under which the G3NA will be exposed to water
? High temperatures or high humidity
? Without proper packing
!WARNING
Minor Humon hazard by electric shock may occasionally occur.
Heatsink must be connected to ground in the end product.
