To remove the Relay from the DIN Track, pull down on the tab with a screwdriver in the direction of the arrow. 

- When a Relay is mounted to DIN Track, use it within the rating for a Relay without a heat sink. 

- Use the following DIN Tracks: PFP-100N or PFP-100N2. 

## **Mounting Bracket** 

## **R99-11 (for the G3NA-240B, G3NA-440B)** 

Use Mounting Bracket R99-11 so that the G3NA-240B/-440B can be mounted with the same pitch as that of the G3N-240B.

## **Safet Precautions y** 

! **Caution** Touching the charged section may occasionally cause minor electric shock. Do not touch the G3NA terminal section (the charged section) when the power supply is ON. Be sure to attach the cover before use. ~~SS~~ 

**3.** Wire the G3NA and tighten screws correctly, observing the following 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. 

! **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 ~~A~~ after the power is turned OFF. ~~;~~ ! **Caution** 

- Abnormal heat generated by terminals may occasionally result in fire damage. Do not operate if the screws on the output terminal are loose. 

## **Tightening Torque** 

~~;~~ The internal snubber circuit is charged and may occasionally 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 completing wiring. Touching the terminals when they are charged ~~A~~ may occasionally result in minor electric shock. 

- 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. 

## ! **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 quickburning fuse, on the power supply line. 

- 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. 

## ■ **Precautions for Safe Use** 

- Mount the DIN Track securely. Otherwise, the DIN Track may fall. 

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. 

- 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. 

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. 

      - 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 

**1.** G3NA malfunction or fire damage may occasionally occur. Do not apply excessive voltage or current to the G3NA terminals. 

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. 

**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. 

**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. 

- 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 ventilated. 

   **6.** Operating Conditions 

- 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. 

   - 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. 

- 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. 

   - 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. 

- 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. 

   **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 

- 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. 

- 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. 

- Use the specified heat sink or one with equivalent or better characteristics. 

Solid State Relay **G3NA**

## **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. 

- 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. 

## ■ **Precautions for Correct Use** 

Please observe the following precautions to prevent failure to operate, malfunction, or undesirable effect on product performance. 

## **Before Actual Operation** 

## ~~ess~~ 

**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 pressure 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 confirm the ratings of specific G3NAs.

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. 

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 mm[2] , Air volume: 0.7 m[3] /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.

- 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 bearings 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.

Solid State Relay **G3NA** 

483 

## ■ **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 conditions 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., climate 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 performance characteristics. 

## **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. 

- 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. 

## ■ **Operation** 

## **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. 

Switch element Snubber circuit Leakage current Nae 

## **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** 

## **4. Do Not Drop** ~~a~~ 

Do not mount the G3NA when your hands are oily or dirty, e.g., with metal powder. These may cause G3NA failure. 

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.
