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

Meaning of Graphic Symbols for Ensuring Product Safety

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.

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.

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.

Operating and Storage Environments

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.

CAUTION Indicates a potentially hazardous situation

which, if not avoided, may result in minor or

moderate injury or in property damage.

Precautions for Safe Use

G3PJ

Installation and Mounting

• Mount the G3PJ in the specified direction. (Refer to Mounting on

page 7.) Excessive heat generated by the G3PJ may cause short-

circuit failures of the output elements or burn damage.

• Make sure that there is no excess ambient temperature rise due to

the heat generation of the G3PJ. If the G3PJ is mounted inside a

panel, install a fan so that the interior of the panel is fully ventilated.

• Make sure the DIN track is securely mounted. Otherwise, the G3PJ

may fall.

• When mounting the heat sink, do not allow any foreign matter

between the heat sink and the mounting surface. Foreign matter

may cause malfunction due to a reduction in the heat radiation

performance.

• If the G3PJ is mounted directly in a control panel, use aluminum,

steel plating, or similar material with a low heat resistance as a

substitute for a heat sink. Using the G3PJ mounted in wood or

other material with a high heat resistance may result in fire or

burning due to heat generated by the G3PJ.

• The G3PJ is heavy. Firmly mount the DIN track and secure both

ends with End Plates for DIN-track-mounting models. When

mounting the G3PJ directly to a panel, firmly secure it to the panel.

Installation and Wiring

• Use wires that are suited to the load current. Otherwise, excessive

heat generated by the wires may cause burning.

• Do not use wires with a damaged outer covering.

Otherwise, it may result in electric shock or ground leakage.

• Do not wire any wiring in the same duct or conduit as power or

high-tension lines. Otherwise, inductive noise may damage the

G3PJ or cause it to malfunction.

• When tightening terminal screws, prevent any non-conducting

material from becoming caught between the screws and the

tightening surface. Otherwise, excessive heat generated by the

terminal may cause burning.

• Do not use the G3PJ with loose terminal screws. Otherwise,

excessive heat generated by the wire may cause burning.

• Use suitable wire lengths for wiring. Inductive noise may

occasionally cause malfunction, failure, or burn damage.

• Always turn OFF the power supply before performing wiring. Not

doing so may cause electrical shock.

Push-In Plus Terminal Block

• Do not wire anything to the release holes.

• Do not tilt or twist a flat-blade screwdriver while it is inserted into a

release hole on the terminal block. The terminal block may be

damaged.

• Insert a flat-blade screwdriver into the release holes at an angle.

The terminal block may be damaged if you insert the screwdriver

straight in.

• Do not allow the flat-blade screwdriver to fall out while it is inserted

into a release hole.

• Do not bend a wire past its natural bending radius or pull on it with

excessive force. Doing so may cause the wire disconnection.

• Do not insert more than one wire into each terminal insertion hole.

• To prevent wiring materials from smoking or ignition, confirm wire

ratings and use the wiring materials given in the following table.

Installation and Usage

• Do not apply a voltage or current that exceeds the rating to any

terminal. Doing so may result in malfunction or burn damage.

• Select a load within the rated values. Not doing so may result in

malfunction, failure, or burning.

• Select a power supply within the rated frequencies. Not doing so

may result in malfunction, failure, or burning.

• If a surge voltage is applied to the load of the Contactor, a surge

bypass(*) will function to trigger the output element. The G3PJ

therefore cannot be used for motor loads. Doing so may result in

load motor malfunction.

*Surge Bypass

This circuit protects the output circuit from being destroyed. This

suppresses the surge energy applied inside the SSR in comparison

with a varistor for the main circuit protection. By alleviating electrical

stress on the electronic components of the SSR's output circuit,

failure and destruction due to surge voltage are suppressed.

Reference value: Surge dielectric strength of 30 kV min.

(Test conditions: 1.2

s standard voltage waveform, peak voltage

of 30 kV, repeated 50 times according to JIS C5442)

The G3PJ in operation may cause an unexpected accident.

Therefore it is necessary to test the G3PJ under the variety of

conditions that are possible. As for the characteristics of the G3PJ, it

is necessary to consider differences in characteristics between

individual G3PJ.

The ratings in this catalog are tested values in a temperature range

between 15°C and 30°C, a relative humidity range between 25% and

85%, and an atmospheric pressure range between 86 and 106 kPa.

It will be necessary to provide the above conditions as well as the load

conditions if the user wants to confirm the ratings of specific SSRs.

Causes of Failure

• Tighten each terminal to the torque specified below. Improper

tightening may result in abnormal heat generation at the terminal,

which may cause burning.

• Do not supply overvoltage to the input circuits or output circuits.

Doing so may result in failure or burning.

• Do not use or store the G3PJ in the following conditions. Doing so

may result in deterioration of performance.

• Locations subject to static electricity or noise

• Locations subject to strong electric or magnetic fields

• Locations subject to radioactivity

For details on close mounting, refer to the related information

under performance characteristics.

Mount the G3PJ in a direction so that the markings read

naturally.

Wiring

• When using crimp terminals, refer to the terminal clearances

shown below.

• Make sure that all lead wires are thick enough for the current.

• To isolate the Relay from the power supply, install an appropriate

circuit breaker between the power supply and the Relay.

Always turn OFF the power supply before wiring the Unit.

Part Names of the Terminal Block

Connecting Wires with Ferrules and Solid Wires

Insert the solid wire or ferrule straight into the terminal block until the

end strikes the terminal block.

If a wire is difficult to connect because it is too thin, use a flat-blade

screwdriver in the same way as when connecting stranded wire.

Connecting Stranded Wires

Use the following procedure to connect the wires to the terminal block.

1. Hold a flat-blade screwdriver at an angle and insert it into the

release hole.

The angle should be between 10° and 15°. If the flat-blade

screwdriver is inserted correctly, you will feel the spring in the

release hole.

With the flat-blade screwdriver still inserted into the release hole,

insert the wire into the terminal hole until it strikes the terminal block.

3. Remove the flat-blade screwdriver from the release hole.

Checking Connections

• After the insertion, pull gently on the wire to make sure that it will

not come off and the wire is securely fastened to the terminal block.

• If you use a ferrule with a conductor length of 10 mm, part of the

conductor may be visible after the ferrule is inserted into the

terminal block, but the product insulation distance will still be

satisfied.

G3PJ

EMI

This is a Class A product (for industrial environments). In a domestic

environment, the G3PJ may cause radio interference, in which case

the user may be required to take appropriate measures.

Noise and Surge Effects

If noise or an electrical surge occurs that exceeds the malfunction

withstand limit for the G3PJ output circuit, the output will turn ON for

a maximum of one half cycle to absorb the noise or surge. Confirm

that turning the output ON for a half cycle will not cause a problem for

the device or system in which the G3PJ is being used prior to actual

use. The G3PJ malfunction withstand limit is shown below.

• Malfunction withstand limit (reference value): 500 V

Note: This value was measured under the following conditions.

Noise duration: 100 ns and 1 μs

Repetition period: 100 Hz

Noise application time: 3 min

Mounting to Control Panel

If the panel is airtight, heat from the G3PJ will build up inside, which

may reduce the current carry ability of the G3PJ or adversely affect

other electrical devices. Be sure to install ventilation holes on the top

and bottom of the panel.

The G3PJ Mounting Pitch (Panel Mounting)

Relationship between the G3PJ and Ducts or Other

Objects Blocking Airflow

Ventilation Outside the Control Panel

Note: 1. If the air inlet or air outlet has a filter, clean the filter regularly

to prevent it from clogging to ensure an efficient flow of air.

2. Do not locate any objects around the air inlet or air outlet,

otherwise the objects may obstruct the proper ventilation of

the control panel.

3. A heat exchanger, if used, should be located in front of the

G3PJ to ensure the efficiency of the heat exchanger.

G3PJ Ambient Temperature

The rated current of the G3PJ is measured at an ambient temperature

of 40°C.

The G3PJ uses a semiconductor to switch the load. This causes the

temperature inside the control panel to increase due to heating

resulting from the flow of electrical current through the load. The G3PJ

reliability can be increased by adding a ventilation fan to the control

panel to dispel this heat, thus lowering the ambient temperature of the

G3PJ.

(Arrhenius's law suggests that life expectancy is doubled by each

10°C reduction in ambient temperature.)

Example: For 10 G3PJ with load currents of 15 A,

0.23 × 10 = 2.3

Thus, 3 fans would be required.

Note: 1. Size of fans: 92 mm × 92 mm, Air volume: 0.7 m3/min,

Ambient temperature of control panel: 30°C

2. If there are other instruments that generate heat in the

control panel in addition to the G3PJ, more ventilation will

be required.

3. Ambient temperature: The temperature that will allow the

G3PJ to cool by convection or other means.

Use ducts that have a

shallow depth, to provide

If the ducts cannot be made
