Solid State Relays (600 VAC Models) G3NA-6 491 Safety Precautions * 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. !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. * Use the specified heat sink or one with equivalent or better characteristics. Abnormal heat generation may cause output elements to short or may cause burning. !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. 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 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. * 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 !CAUTION Screw size 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 may occasionally result in minor electric shock. Tightening torque M4 1.2 N*m M5 2.0 N*m * Abnormal heat generated by terminals may occasionally result in fire damage. When tightening terminal screws, be sure that no non-conductive material is caught in screw. !CAUTION * For G3NA Relays of 50 A or higher, use crimp terminals of an appropriate size for the wire diameter for M5 terminals. 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. * Use wires that are suitable for the load current and voltage. Abnormal heat generated by the wires may result in fire damage or melting of the sheath, causing electric shock. * Do not use any wires with damaged sheaths. These may cause electric shock or leakage. Precautions for Safe Use * Do not place wiring in the same conduit or duct as high-voltage lines. Induction may cause malfunction or damage. 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. * 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. 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. Heat generated from an G3NA error may occasionally 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 ventilated. * Tighten the G3NA screws securely. Tightening torque: 0.78 to 0.98 N*m * Abnormal heat generation may cause output elements to short or may cause burning. * Tighten the heat sink screws securely. Tightening torque: 0.98 to 1.47 N*m * The G3NA may fall if it is not mounted correctly. * 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. 4. 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. * 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 Toshiba Silicone's YG6260 or Sinetsu Silicone's G746, or a similar material to the heat sink before mounting * Never apply voltage or current to the I/O terminals that exceeds the rated range. Doing so may result in malfunction, damage, or burning. 5. 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 492 Solid State Relays (600 VAC Models) G3NA-6 Operating and Storage Locations Relationship between SSRs and Duct Height Do not use or store the G3NA in the following locations. Doing so may result in damage, malfunction, or deterioration of performance characteristics. Incorrect Example Mounting surface Duct Mounting surface Vertical direction Airflow SSR Base Duct Duct Do not surround the SSR with ducts, otherwise the heat radiation of the SSR will be adversely affected. Countermeasure 2 50 mm max. (A height of no more than half the SSR's height is recommended.) Duct Mounting surface * Do not use or store in locations subject to direct sunlight. * Do not use in locations subject to ambient temperatures outside the range -30 to 80C. * 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 100C. * 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. Countermeasure 1 Duct Use short ducts. If the ducts cannot be shortened, place the SSR on a metal base so that it is not surrounded by the ducts. Ventilation Outside the Control Panel Be aware of airflow Duct Ventilation outlet (axial fan) Precautions for Correct Use Please observe the following precautions to prevent failure to operate, 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 15C and 30C, 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. Mounting Method SSR Mounting Pitch (Panel Mounting) The correct mounting direction is vertical as in the below figures. Duct 60 mm min. Air inlet 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 40C. * 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 10C reduction in temperature will double the expected life.)

Be sure that this does not cause any problems. Direct Mounting Loss time * Prepare mounting holes as shown in the diagram. Tightening torque: 0.98 to 1.47 N*m Using DC Loads 640.3 For a DC or L load, a diode should be connected in parallel the load to absorb the counter electromotive force of the load. 1300.3 Load Input Four, 4.5 dia. or M4 holes 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. Failure 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. 494 Solid State Relays (600 VAC Models) G3NA-6 SSR Load power supply Precautions on Operating and Storage Environments 1. Operating Ambient Temperature 3. Vibration and Shock 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. 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. 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). 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. 2. Transportation 5. Oil When transporting the G3NA, observe the following points. Not doing so may result in damage, malfunction, or deterioration of performance characteristics. 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 2. Screw Tightening Torque 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. 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 Varistor Trigger circuit Input circuit Switch element Snubber circuit Do not mount the G3NA when your hands are oily or dirty, e.g., with metal powder. These may cause G3NA failure. Leakage current 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-P250N), which weighs 2.5 kg.
