Engineering Data
Ambient Temperature
Note: 1. The ambient operating temperature range is −15 to 55°C, but take the following considerations into account. When the ambient
temperature exceeds 40°C, reduce the maximum load current as shown below.
2. At least 20 mm must be provided on the left and right sides of the G3PW-A260E@. If you must use side-by-side mounting, then reduce
the maximum load current when the ambient temperature is over 30°C.
3. Certification for safety standards was obtained with a mounting interval of 20 mm.
4. Leave sufficient space for ventilation.
5. Do not install the Power Controller above devices that generate significant amounts of heat, such as heaters, transformers, and high-
capacity resistors.
6. If the ambient temperature reaches 55°C or higher, install an air conditioner to lower the temperature.
Resistance to Inrush Current (For repetitive inrush current, keep the inrush current below the values shown by the dotted lines.)

Safety Precautions
Do not attempt to disassemble the Power Controller
while the power is being supplied. Doing so may
occasionally result in strong electric shock.
Do not touch any of the terminals while the power is
being supplied. Also, always attach the terminal block
cover after completing wiring. Touching live terminals
may occasionally result in serious injury due to
electric shock.
Fail-safe measures must be taken by the customer to
ensure safety in the event of incorrect, missing, or
abnormal signals caused by broken signal lines,
momentary power interruptions, or other causes.
Abnormal operation may result in serious accidents.
Do not use the Power Controller where subject to
flammable or explosive gas. Otherwise, explosion may
occur.
Use the wire sizes given in this document and use
twisted copper wires or solid copper wire.
Use crimp terminals with insulative sleeves. If the
crimp terminals do not come with insulative sleeves,
attach insulative sleeves. Use the size of crimp terminals
specified in this document.
Make sure that the phases match for load terminal T1
and power supply terminal 4 (N), and for load terminal
L1 and power supply terminal 5 (L). Insert suitable
fuses in the power supply line and load output line to
protect the circuits.
The Power Controller will not operate normally if the
wiring is not correct, and the load may be damaged.
Leave at least 100 mm of space above and below the
Power Controller when installing it to allow heat to
dissipate. Do not obstruct the area around the Power
Controller and especially the area around the heat
sink.
Install the Power Controller in the direction shown in
this Instruction Sheet. The Power Controller generates
a lot of heat and it uses natural heat convection for
cooling. Installing the Power Controller in the wrong
direction may cause in malfunctions or accidents.
Do not touch the terminal sections while a voltage is
being applied after the power supply terminal block
and load terminal block have been wired.
The power supply terminal block and load terminal
block are not isolated to enable an alarm function.
Electric shock may occur.
The Power Controller and the heat sink become very
hot. Do not touch anything but the setting keys while
power is being supplied or jus t after the power suppl y
is turned OFF. Doing so may cause burns.
Do not attempt to disassemble, modify, or repair the
Power Controller or touch any of the internal parts.
Minor electric shock, fire, or malfunction may
occasionally occur.
Do not allow chips or filings from installation work,
pieces of metal, or wire clippings to enter the Power
Controller. Doing so may occasionally result in minor
electric shock, fire, or malfunction.
Always connect the load to load terminal T1. Also,
always connect power supply terminal 4 (N) directly to
the power supply. Do not connect it through the load.
If the wiring is not correct, the fault detection function
of the Power Controller will indicate “E10” and stop the
output operation. Check the connection again.
When using the Power Controller to control the
primary side of a transformer, do not open the circuit
on the secondary side of the transformer while the
Power Controller is operating.
Do not touch the connecting cables while power is
being supplied. Static electricity from your body may
cause malfunctioning.
If a malfunction in the Power Controller prevents
control operations or if an alarm cannot be output, it
may occasionally cause damage to the connected
equipment and devices. To maintain safety in the event
of a malfunction in the Power Controller, always take
appropriate safety measures, such as installing a
separate monitoring system.
Set the parameters of the Power Controller so that they
are suitable for the system being controlled. If they are
not suitable, unexpected operation may occasionally
result in property damage or accidents.
Tighten the terminal screws to the torque specified in
this Instruction Sheet. If the screws are loose, it may
occasionally cause a fire.
WARNING CAUTION
G3PW
9
OMRON constantly strives to improve quality and reliability. The
G3PW, however, uses semiconductors, and semiconductors may
commonly malfunction or fail. In particular, it may not be possible to
ensure safety if the G3PW is used outside the rated ranges.
Therefore, always use the G3PW within the ratings. When using the
G3PW, always design the system to ensure safety and prevent
human accidents, fires, and social harm in the event of G3PW failure.
System design must include measures such as system redundancy,
measures to prevent fires from spreading, and designs to prevent
malfunction.
1. Do not apply a voltage or current in excess of the ratings to the
terminal sections of the G3PW. Doing so may result in failure of
the G3PW or fire damage.
2. Do not use the G3PW with loose terminals screws. Abnormal
terminal heat may result in fire damage.
3. Do not obstruct the airflow around the heat sink of the G3PW.
Abnormal heat may result in failure due to shorting of the output
terminals or fire damage.
4. Be sure to read the Precautions for Correct Use to correctly
perform wiring and tighten screws. Using the G3PW with
incorrect wiring or insufficient screw tightening may result in fire
damage due to abnormal heat when the power is supplied.
Installation Environment
•Use the Power Controller within the rated ambient temperature and
humidity ranges.
•If multiple Power Controllers are installed side-by-side or vertically,
the heat that is generated will cause the internal temperatures of
the Power Controllers to rise and will shorten their service life. In
these kinds of installations, take suitable measures, such as
installing fans for forced cooling.
•The Power Controller is designed for indoor use only. Also, do not
use the Power Controller in the following environments.
• Locations subject to water, oil, or chemicals
• Locations subject to direct sunlight
• Locations where dust or corrosive gases (in particular, sulfuric or
ammonia gas) are present
• Locations subject to extreme temperature changes
• Locations where icing or condensation may occur
• Locations subject to excessive shocks or vibration
• Locations subject to direct heat radiated from heating devices
Installation and Wiring
•When installing the Power Controller, always securely tighten the
top mounting screws first. When removing the Power Controller,
always remove the bottom mounting screws first.
•Take safety measures, such as wearing safety shoes, in case the
Power Controller falls.
•Touch the Power Controller only after first touching a grounded
metal object to discharge any static electricity from your body.
•Always ground the Power Controller to 100 Ω or less. There are no
ground terminals provided, so use the heat sink mounting screws
as ground terminals.
•Check the terminal number and polarity for each input before
connecting it.
•Use copper twisted wire in the sizes specified in this Instruction
Sheet.
•Use insulated crimp terminals with insulation sleeves. If using
crimp terminals that are not insulated, cover them with insulation
sleeves. Also, use terminals of the sizes specified in this Instruction
Sheet.
•Insert connectors all the way.
•Do not connect anything to unused terminals.
Safety Measures and Checking
•Install a switch or circuit breaker so that the operator can
immediately turn OFF the power, and provide a suitable display.
•Apply the power supply voltage through the contacts of a switch,
relay, or similar device so it reaches the rated voltage within 2 s. If
the power supply voltage is increased gradually, the power supply
may not be reset or outputs may malfunction.
•Use a power supply voltage, input voltage, input current, and load
within the specifications and rated ranges for the Power Controller.
•Use a load that draws a current at the maximum output that is
within the rated current range of the Power Controller. If the current
drawn by the load is not within the rated current range, malfunction
or fire may occur.
•Make sure that the protective cover is attached to the load terminal
block before using the Power Controller. Failure to do so may
damage internal components due to mechanical stress.
Preventing Inductive Noise
•Allow as much space as possible between the Power Controller
and devices that generate powerful high frequencies (high-
frequency welders, high-frequency sewing machines, etc.) or
surge.
•Keep the signal lines that connect to the Power Controller's
terminal block away from power cables carrying high voltages or
large currents. Also, do not wire power lines together with or
parallel to Power Controller wiring. Using shielded cables and
using separate conduits or ducts is recommended.
•Attach a surge suppressor or noise filter to peripheral devices that
generate noise (in particular, motors, transformers, solenoids,
magnetic coils or other equipment that have an inductance
component).
•When a noise filter is used at the power supply, first check the
voltage or current, and attach the noise filter as close as possible
to the Power Controller.
Cleaning
•Do not use paint thinner or similar chemical to clean with. Use
commercially available standard grade alcohol.
Storage
•Store the Power Controller within the rated ambient temperature.
Precautions for Safe Use

Installation Direction
For cooling efficiency, install the Power Controller in the correct
direction. The G3PW generates a lot of heat, and it uses natural heat
convection for cooling. Installing the Power Controller in the wrong
direction may cause it to malfunction or to be damaged.
Wiring the Power Supply and Load Circuits
The G3PW will not operate correctly if the wiring is not correct. The
failure detection function of the G3PW will stop the output from
operating.
Connect the AC power supply to power supply terminals 4 (N) and 5
(L).
Connect the load to load terminal T1 and to the power supply, and
then connect the power supply to load terminal L1 through a fast-
acting fuse.
The AC power supply ground polarity and the G3PW terminal block
polarity are not related, but connect the 4 (N) and 5 (L) terminals on
the command input/power supply terminal block and the T1 and L1
terminals of the load terminal block to power supplies with the same
phases.
Wiring the Load Terminal Block
Recommended Wires
When connecting to the load terminals, use the specified wire size for
each model of Power Controller.
*Crimp terminals that conform to UL and CSA specifications must be
used.
Recommended Crimp Terminals
•Either use insulated crimp terminals or cover the crimp terminals
with insulating sleeves.
•Always use the following crimp terminals to wire the load terminals.
•Do not connect more than two crimp terminals to one terminal
screw.
Recommended Fuses
*Ask your OMRON representative for UL certified products.

ON/OFF Voltage Input (0 or 5 VDC)
When using an ON/OFF voltage input, connect the positive and
negative signal wires to terminals 1 and 3, respectively and apply a
command voltage that is 0 or 5V.
The G3PW may be damaged if a command voltage that is higher than
5 V is applied. If it is necessary to apply more than 5 V, split the
voltage as shown below by inserting resistance in the line to terminal
1 and applying the voltage across terminals 1 and 3. The internal
impedance between terminals 1 and 3 is 30.1 kΩ.
Command Input and Power Supply Wire Sizes
Recommended Crimp Terminals
Always use the following crimp terminals (for M3.5) to wire to the
command input and power supply terminals.
Wiring the Control Terminal Block
Recommended Wire Sizes and Connection Method
G3PW-A2@@E@-S (Models with terminal blocks with small
slotted screws)
G3PW-A2@@E@-C (Models with screwless clamp terminal block)
Wire Sizes for Control Terminals (Models with Small Slotted
Screws or Screwless Clamp Terminals)
•Use copper AWG 26 to 16 twisted-pair cable when connecting the
wires directly.
•Strip the wire sheathing for the following lengths, according to the
connector type.
• Small slotted screw terminals: 7 mm
• Screwless clamp terminals: 9 mm
•When using twisted wires, it is recommended that you attach a
ferrule with an insulating cover that conforms to DIN 46228-4 and
connect the ferrule to the terminal.
•Use shielded twisted-pair wires for RS-485 communications wires.
A maximum of 500 m total of wiring can be used.
Failure Detection Wiring
Sufficiently consider the safety design of the system design so that
the load circuit is turned OFF using the alarm output when a failure is
detected in the G3PW.

Wiring an External Noise Filter
Always insert a noise filter in the power supply lines to the G3PW.
Grounding
Always ground the Power Controller to 100 Ω or less. There are no
ground terminals provided, so use the heat sink mounting screws as
ground terminals.
