panasonic corporation automation controls business unit industrial.panasonic.com/ac/e/ ev (aev) asctb233e 201209-t notes 1. usage, transport and storage conditions 1) temperature: ?0 to +80 c ?0 to +176 f 2) humidity: 5 to 85% rh (avoid freezing and condensation.) the humidity range varies with the temperature. use within the range indicated in the graph below. 3) atmospheric pressure: 86 to 106 kpa temperature and humidity range for usage, transport, and storage 4) condensation condensation forms when there is a sudden change in temperature under high temperature and high humidity conditions. condensation will cause deterioration of the relay insulation. 5) low temperature, low humidity environments the plastic becomes brittle if the relay is exposed to a low temperature, low humidity environment for long periods of time. 2. when installing the relay, always use washers to prevent the screws from loosening. ?regarding the torque value for contact terminal, it is intended that secure an electrical connection stability by getting enough contact pressure (axial force) of ?ing part. therefore, please do not use the screw (a bolt and a nut) preventing looseness needing running torque (prevailing torque type and self lock type) because enough tightening force in axial direction may not be secured. in addition, there is high possibility that a case of a relay may be broken if users use the nut for ev80a and ev120a. because excessive torque is applied to a case of a relay before generation of contact pressure. (axial force). ?regarding the torque value for the main body of a relay, please use suitable screw on own veri?ation. 3. condition of tightening screw tighten each screw within the rated range given below. exceeding the maximum torque may result in breakage. mounting is possible in either direction. ?m4 screw (for 10a type): 1.8 to 2.7 n? ?m5 screw (for 20a, 80a, 120a, 200a and 300a types): 3 to 4 n? ?m5 (for 80a type): 3 to 4 n? ?m6 (for 120a and 200a types): 6 to 8 n? ?m8 (for 300a type): 10 to 12 n? 4. electrical life this relay is a high-voltage direct-current switch. in its ?al breakdown mode, it may lose the ability to provide the proper cut-off. therefore, do not exceed the indicated switching capacity and life. (please treat the relay as a product with limited life and replace it when necessary.) in the event that the relay loses cut-off ability, there is a possibility that burning may spread to surrounding parts, so con?ure the layout so that the power is turned off within one second. 5. permeation life of internal gas this relay uses a hermetically encased contact (capsule contact) with gas inside. the gas has a permeation life that is affected by the temperature inside the capsule contact (ambient temperature + temperature rise due to ?w of electrical current). f or this reason, make sure the ambient operating temperature is between ?0 and 80 c ?0 and +176 f (200a and 300a types: max. 85 c 185 f ), and the ambient storage temperature is between ?0 and 85 c ?0 and +185 f . 6. the coils (300 a type) and contacts (all type) of the relay are polarized, so follow the connection schematic when connecting the coils and contacts. type 300 a contains a reverse surge voltage absorption circuit; therefore a surge protector is not needed. 7. for the 300 a type, drive the coil with a quick startup. (built-in one-shot pulse generator circuit) 8. after the on signal enters the 300a type, automatic coil current switching occurs after approximately 0.1 seconds. do not repeatedly turn it off within that 0.1 seconds interval, as doing so may damage the relay. 9. be careful that foreign matter and oils and fats kind don? stick to the main terminal parts because it is likely to cause terminal parts to give off unusual heat. also, please use the following materials for connected harnesses and bus bars. 10a type: min. 2 mm 2 nominal cross-sectional area 20a type: min. 3 mm 2 nominal cross-sectional area 80a type: min. 15 mm 2 nominal cross-sectional area 120a type: min. 38 mm 2 nominal cross-sectional area 200a type: min. 60 mm 2 nominal cross-sectional area 300a type: min. 100 mm 2 nominal cross-sectional area 10. as a guide, the insertion strength of the plug-in terminal into the relay tab terminal should be 40 to 70n (10a type), 40 to 80n (20a type). please select a plug-in terminal (?t connection terminal) which comply with jis c2809-1999. 10a type: for plate thickness 0.5mm and #187 tab terminal 20a type: for plate thickness 0.8mm and #250 tab terminal 11. avoid excessive load applied to the terminal in case of installing such as a bus bar etc., because it might adversely affect the opening and closing performance. 12. use the speci?d connector for the connector terminal connection (80a, 120a and 300a) yazaki corporation 7283 ?1020 or equivalent humidity, %rh tolerance range 85 5 (avoid condensation when used at temperatures higher than 0 c 32 f ) (avoid freezing when used at temperatures lower than 0 c 32 f ) 800?0 +176+32?0 temperature, c f
panasonic corporation automation controls business unit industrial.panasonic.com/ac/e/ ev (aev) asctb233e 201209-t for general cautions for use, please refer to the ?autions for use of automotive relays http://industrial.panasonic.com/ac/e/ 13. cautions for use 1) regarding cautions for use and explanation of technical terms, please refer to our ?utomotive relays automation controls group catalog? 2) additionally the ambient temperature and condition for your application should be considered because pick-up and drop-out voltage will be changed. 3) if it includes ripple, the ripple factor should be less than 5%. for coil surge absorption, please use a zener diode or varistor, etc., so that the clamp voltage reaches 1.5 times or more (at least 18 v for rated 12 v type) the rated operation voltage. if only a diode is connected in parallel with the relay coil, the contact opening velocity will become slow and suf?ient cutoff performance cannot be guaranteed. please avoid such usage. ex. 1: when using a varistor recommended varistor; maximum energy: more than 1j (however, please make settings using values that take into consideration the worst case scenario.) var istor voltage: for 12 v dc input, min. 18 v ex. 2: when using a zener diode (circuit) 4) lifetime is speci?d under the standard test conditions in jis c 5442. (temperature 15 to 35 c 59 to 95 f , humidity 25%rh to 85%rh) lifetime is dependent on the coil driving circuit, load type, operation frequency and ambient conditions. check lifetime under the actual condition. especially, contact terminals have polarity. so if the contact terminals were connected with opposite pole, the electric life would be shorter. 5) when applying current which includes precipitous changes or r ipple, the relay may generate buzzing sound. therefore, please con?m with the actual load. 6) if the relay is used while exceeding the coil rating, contact rating or cycle lifetime, this may result in the risk of overheating. 7) as a general rule, do not use a relay if it has been dropped. 8) take care to avoid cross connections as they may cause malfunctions or overheating. 9) when the screws for ?ing relay-body and for additional terminal are tightened, it should be used within the range of decided torque. 10) avoid mounting the relay in strong magnetic ?lds (near a transformer or magnet) or close to an object that radiates heat. 11) if the several relays are mounted closely or a heat- generation object is close to the relay, take care to check the abnormal temperature-rise and the insulation distance between the terminals outside of the relay. 12) the relay contacts are encapsulated in an inert gas atmosphere. care must be exercised when the relay is to be used or stored at high ambient temperature. 13) if the power is turned off and then immediately on after applying the rated voltage (current) continuously to the relay s coil and contact, the resistance of the coil will increase due to a rise in the coil temperature. this causes the pick-up voltage to rise, and possibly exceed the rated pick-up voltage. in these circumstances, take measures such as reducing the load current, limiting the duration of current ?w, and applying a coil voltage higher than the rated operating voltage (quick start). 14) in case using a capacitive load (c-load), please take a countermeasure as pre-charging to the capacitive load so that the inrush current will not surpass 60a. the relay might have a contact welding without such countermeasure. 15) if the relay is used for an inductive load (l load) such that l/r > 1ms, add surge protection in parallel with the inductive load. if this is not done, the electrical life will decrease and cut- off failure may occur. 16) use the suitable wire for wire at the load side according to the current. if the wire diameter is small, the maximum rated contact current cannot be guaranteed. (ex.) carrying current; 60a: diameter of 15mm 2 or more 17) take care to disconnect to the power supply when wiring. 18) do not switch the contacts without any load as the contact resistance may become increased rapidly. 19) the relay satis?s the protection level of jis d 0203 r2 (of waterproof). please take any countermeasures additionally if it should be installed in the place where higher protection level is required. 20) do not use this product in such atmosphere where any kind of organic solvent (as benzene, thinner and alcohol) and the strong alkali (as ammonia and caustic soda) might be adhered to this product. 21) be careful that foreign matter and oils and fats kind don? stick to the main terminal parts because it is likely to cause terminal parts to give off unusual heat. 22) do not make additional manufacturing upon the relay housing. 23) for ac shutoff these is no contact polarity, but con?m the electric life using the actual load. 12v relay coil zd18v d zd18v + diode voltage clamp voltage (1) 12v relay coil zd30v clamp voltage zd30v zener voltage 30v ? 12v=18v (2)
