12 solid state relay g3na safety precautions precautions for safe use although omron continuously strive s to improve the quality and reliability of our relays, the g3na contains semiconductors, which are generally prone to occasi onal malfunction and failure. maintaining safety is particularly difficult if a relay is used outside of its ratings. always use the g3na wi thin 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 desi gns 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 inte rior 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 char acteristics will be reduced, possibly c ausing g3na failure. ? apply a thin layer of toshiba si licone?s yg6260 or sinetsu sili- cone?s g746, or a similar product to the heat sink before mount- ing. ? if a material with high thermal resistance, such as wood, is used, heat generated by the g3na may occasiona lly 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 term inals 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 term inals may occasionally result in fire damage. when tightening terminal screws, be sure that no non-conductive foreign ma tter 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 h eat 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 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 el ectric 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 protecti ve device, such as a quick- burning fuse, on the power supply line. ! caution ! caution ! caution ! caution ! caution screw size tightening torque m4 1.2 n ?

solid state relay g3na 15 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, possibl y 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 thermostat can be used to stop the operation of the ssr. implement an overheating preventi on 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 sys- tem. ? 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-cap acity 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 i nput 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 runni ng continuously during the on/off operation of the ssr. this is to allow residual heat to dissipate while the ssr is off. noise terminal voltage according to en55011 the g3na-utu complies with en55011 standards when a capacitor is connected to the load power suppl y as shown in the following cir- cuit diagram. ? connect capacitor c1 to both sides of the input terminals for a g3na with a dc input. ? connect capacitor c2 to both sides of the load power supply out- put. ? connect the varistor to both sides of the g3na output terminals. ? do not use an input line that is longer 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. load g3na load side input side y92b-p250nf thermostat (nc contact) circuit breaker (contact side) coil power supply circuit breaker circuit breaker (coil side) output input c1 c2 g3na-utu type load capacitor c1 0.1 f 3 m max. varistor ? g3na-2 @@ : 470 v, 0.6 w ? g3na-4 @@ : 910 v, 0.8 w capacitor c2 ? g3na-2 @@ : 1 f, 250 vac ? g3na-4 @@ : 0.5 f, 500 vac g3na rated load current fuse model manufacturer applicable ssr 5 a 60lff5 kyosan electric manufacturing company g3na-205b 8 a 60lff8 g3na-210b 10 a 60lff10 15 a 60lff15 g3na-220b 20 a 60lff20 50sha20 25 a 60pff25 50sha25 g3na-240b 30 a 60pff30 50sha30 40 a 50sha40 45 a 50sha45 50 a 50sha50 g3na-275b-utu 75 a 50sha75 80 a 50sha80 g3na-290b-utu 100 a 50shb100 loss time ssr input load load power supply
16 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 result ing in malfunction or burning. when using the g3na, design the s ystem to allow heat dissipation sufficient to stay below the load current vs. ambient temperature characteristic curve. note also t hat the ambient temperature of the g3na may increase as a result of environmental condi tions (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 excessi ve 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 ma rkings on the g3na. 5. oil do not allow the g3na terminal cover to come in contact with oil. doing so will cause the cove r to crack and become cloudy. 1. leakage current a leakage current flows through a s nubber 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 t he 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. operation input circuit trigger circuit switch element snubber circuit varistor leakage current
