Note: The heat sink area refers to the combined area

of the sides of the heat sink that radiate heat.

For example, when a current of 18 A is allowed

to flow through the SSR at 40°C, the graph

shows that the heat sink area is about 450 cm2.

Therefore, if the heat sink is square, one side of

the heat sink must be 15 cm ( ) or

Safety Precautions

■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.

3. Wire the G3NA and tighten screws correctly, observing the follow-

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

•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.

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.

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.

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.

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.

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.

Operating and Storage Locations

Do not use or store the G3NA in the following locations. Doing so

may result in damage, malfunction, or deterioration of performance

characteristics.

■Precautions for Correct Use

Please observe the following precautions to prevent failure to oper-

ate, malfunction, or undesirable effect on product performance.

Before Actual Operation

1. The G3NA in operation may cause an unexpected accident.

Therefore it is necessary to test the G3NA under the variety of

conditions that are possible. As for the characteristics of the

G3NA, it is necessary to consider differences in characteristics

between individual SSRs.

2. Unless otherwise specified, 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 pres-

sure range between 88 and 106 kPa (standard test conditions

according to JIS C5442). It will be necessary to provide the above

conditions as well as the load conditions if the user wants to con-

firm the ratings of specific G3NAs.

Mounting Method

SSR Mounting Pitch (Panel Mounting)

Relationship between SSRs and Duct Height

Ventilation Outside the Control Panel

If the air inlet or air outlet has a filter, clean the filter regularly to pre-

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

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

the objects may obstruct the proper ventilation of the control panel.

A heat exchanger, if used, should be located in front of the SSRs to

ensure the efficiency of the heat exchanger.

•Please reduce the ambient temperature of SSRs. The rated load

current of an SSR is measured at an ambient temperature of 40°C.

•An SSR uses a semiconductor in the output element. This causes

the temperature inside the control panel to increase due to heating

resulting from the passage of electrical current through the load. To

restrict heating, attach a fan to the ventilation outlet or air inlet of

the control panel to ventilate the panel. This will reduce the ambient

temperature of the SSRs and thus increase reliability. (Generally,

each 10 °C reduction in temperature will double the expected life.)

Example: For 10 SSRs with load currents of 10 A,

0.16 x 10 = 1.6

Thus, 2 fans would be required.

Size of fans: 92 mm2, Air volume: 0.7 m3/min,

Ambient temperature of control panel: 30 °C

If there are other instruments that generate heat in the control panel

other than SSRs, additional ventilation will be required.

•Do not use or store in locations subject to direct sunlight.

•Do not use in locations subject to ambient temperatures outside

the range –20 to 60°C.

•Do not use in locations subject to relative humidity outside the

range 45% to 85% or locations subject to condensation as the

result of severe changes in temperature.

•Do not store in locations subject to ambient temperatures outside

the range –30 to 70°C.

•Do not use or store in locations subject to corrosive or flammable

gases.

•Do not use or store in locations subject to dust (especially iron

dust) or salts.

•Do not use or store in locations subject to shock or vibration.

•Do not use or store in locations subject to exposure to water, oil, or

chemicals.

•Do not use or store in locations subject to high temperatures or

high humidity.

•Do not use or store in locations subject to salt damage.

•Do not use or store in locations subject to rain or water drops.

Thermostat Ratings

Fan/Thermostat Characteristics

•Use a commercial power supply (50/60 Hz) for the Fan.

•Be sure to turn OFF the power supply and wait for the blades to

stop before inspecting the Fan.

•High-precision ball bearings are used in the fan and these may be

damaged if the Fan is dropped or otherwise subjected to shock.

The life and characteristics of the Fan will be reduced if the bear-

ings are damaged. Do not subject the Fan to shock.

•The life of the Fan depends on the ambient temperature, As a

guideline, the Fan life is 40,000 hours for continuous usage at 40°C.

•Be sure there are no objects near the air vents that would restrict

air flow and no loose objects, such as electrical lines.

•The Fan is an OMRON R87F-A4A-93HP (200 VAC) Fan. Use the

same model of Fan for replacement.

•The tightening torque of the mounting screw when replacing the

Fan is 0.44 N•m.

•Terminals equivalent to Faston #110 are used for the Fan power

supply terminals.

•Refer to the following table for the OMRON Fan power supply plug

Preventing Overheating with a

High-capacity Heat Sink (Y92B-P250NF)

•When the High-capacity Heat Sink is used, high-capacity switching

at 75 A or 90 A requires forced cooling with a fan. Connect the Fan

to a power supply according to its ratings specifications.

•If the Fan stops due to a power supply error, due to foreign matter

in the power supply connection, or due to aging, the Heat Sink will

heat to high temperatures, possibly resulting in failure of the SSR or

adverse affects on other devices. Implement an overheating pre-

vention measure, such as turning OFF the load current, if the Heat

Sink overheats.

•

A thermostat is provided to detect overheating. The thermostat uses a

NC contact, i.e., the circuit will be opened for overheating. This thermo-

stat can be used to stop the operation of the SSR. Implement an over-

heating prevention measure by using this signal to output an alarm or

perform another response applicable to the system. Also, confirm that

there is no problem with the overall system.

•Do not connect the thermostat directly to the load power supply.

Connect it to a contactor or other shutoff device connected above

the SSR.

•Terminals equivalent to Faston #187 are used for the thermostat

terminals.

•Do not place heat-dissipating silicon grease on the thermostat.

•Do not solder the thermostat terminals.

•The following diagram shows a protective circuit example.

Ventilating a High-capacity Heat Sink

(Y92B-P250NF)

•Refer to Ventilation Outside the Control Panel.

Operating Conditions

•Do not apply currents exceeding the rated current otherwise, the

temperature of the G3NA may rise excessively.

•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.

•Do not apply overvoltages to the input circuit or output circuit. Fail-

ure or burning may result.

•Do not drop the G3NA or otherwise subject it to abnormal shock.

Malfunction or failure may result.

•Keep the cooling system running continuously during the ON/OFF

operation of the SSR. This is to allow residual heat to dissipate

while the SSR is OFF. (load current 75A, 90A models)

EMC Directive Compliance (For -UTU type)

EMC directives can be complied with under the following conditions.

1. AC-switching models

•A capacitor must be connected to the input power supply.

•A capacitor, varistor and toroidal core must be connected to the

load power supply.

•The input cable must be less than 3 m.

2. DC-switching models

•The input cable must be less than 3 m.

Loss Time

The loss time will increase when the G3NA is used at a low applied

voltage or current. Be sure that this does not cause any problems.

Using DC Loads

For a DC or L load, a diode should be connected in parallel the load

to absorb the counter electromotive force of the load.

Fuses

Connect a quick-break fuse in series with the load as a short-circuit

protection measure. Use one of the fuses in the following table or one

with equivalent or better characteristics.

Recommended Fuses

Reverse Connection

The output terminal side of the G3NA-D210B is connected to a built-

in diode to protect the SSR from damage that may result from

reverse connection. The SSR, however, cannot withstand one minute

or more if the wires are connected in reverse. Therefore, pay the

utmost attention not to make polarity mistakes on the load side.

484 Solid State Relay G3NA

■Precautions on Operating and Storage Environments

1. Operating Ambient Temperature

The rated value for the ambient operating temperature of the G3NA

is for when there is no heat build-up. For this reason, under condi-

tions where heat dissipation is not good due to poor ventilation, and

where heat may build up easily, the actual temperature of the G3NA

may exceed the rated value resulting in malfunction or burning.

When using the G3NA, design the system to allow heat dissipation

sufficient to stay below the Load Current vs. Ambient Temperature

characteristic curve. Note also that the ambient temperature of the

G3NA may increase as a result of environmental conditions (e.g., cli-

mate or air-conditioning) and operating conditions (e.g., mounting in

an airtight panel).

2. Transportation

When transporting the G3NA, observe the following points. Not doing

so may result in damage, malfunction, or deterioration of perfor-

mance characteristics.

•Do not drop the G3NA or subject it to severe vibration or shock.

•Do not transport the G3NA if it is wet.

•Do not transport the G3NA under high temperatures or humidity.

•Do not transport the G3NA without packing it properly.

3. Vibration and Shock

Do not subject the G3NA to excessive vibration or shock. Otherwise

the G3NA may malfunction and internal components may be

deformed or damaged, resulting in failure of the G3NA to operate. To

prevent the G3NA from abnormal vibration, do not install the G3NA in

locations or by means that will subject it to vibration from other

devices, such as motors.

4. Solvents

Do not allow the G3NA or the resin portion of the Fan’s thermostat to

come in contact with solvents, such as thinners or gasoline. Doing so

will dissolve the markings on the G3NA.

5. Oil

Do not allow the G3NA terminal cover to come in contact with oil.

Doing so will cause the cover to crack and become cloudy.

1. Leakage Current

A leakage current flows through a snubber circuit in the G3NA even

when there is no power input. Therefore, always turn OFF the power

to the input or load and check that it is safe before replacing or wiring

the G3NA.

2. Screw Tightening Torque

Tighten the G3NA terminal screws properly. If the screws are not

tight, the G3NA will be damaged by heat generated when the power

is ON. Perform wiring using the specified tightening torque.

3. Handling Relays

Do not mount the G3NA when your hands are oily or dirty, e.g., with

metal powder. These may cause G3NA failure.

4. Do Not Drop

Be careful not to drop a Relay or Heat Sink onto any part of your

body while working. Injury may result. This is particularly true for the

High-capacity Heat Sink (Y92B-P250NF), which weighs 2.5 kg.
