However, some electric items/ components do in fact fail despite our efforts. The durability of products also varies depending on service environments and conditions. Please check your product under actual service conditions before use. If you continue to use a product in a poor condition, items with deteriorated insulation performance may generate abnormal heat or smoke or even ignite. The product's failure or end of service life may cause accidents involving risks to human health, fire, or danger to the public at large. We advise you to apply safety measures and regular maintenance work, such as the use of redundant design, fireproofing, and malfunction-preventing design, to rule out such accidents. For general cautions for use, please refer to the "Automotive Relay Users Guide". Precautions when using EC-N relays Usage, transport and storage conditions 1. Amibient temperature, humidity and air pressure during usage, transport and storage of the relay. (1) Temperature: –40 to +85°C (2) Humidity: 5 to 85% RH (Avoid icing and condensation.) Notes: The humidity range varies with the temperature. Use within the range indicated in the graph below. (3) Air pressure: 86 to 106 kPa [Temperature and humidity range for usage, transport, and storage] Humidity (％ RH) 85 Allowable range Avoid icing when used at temperatures lower than 0°C Avoid condensation when used at temperatures higher than 0°C 5 -40 0 Ambient temperature (℃) 85 2. Water condensation Water condensation occurs when the ambient temperature drops suddenly from a high temperature and humidity, or, the relay is suddenly transferred from a low ambient temperature to a high temperature and humidity. Condensation causes the failures like insulation deterioration, wire disconnection and rust etc. Panasonic Corporation does not guarantee the failures caused by condensation. The heat conduction by the equipment may accelerate the cooling of relay itself, and the condensation may occur. Please confirm no condensation in the worst condition of the actual usage. (Special attention should be paid when high temperature heating parts are close to the relay. Also, please consider the condensation may occur inside of the relay.) 3. Icing Please check the icing when an ambient temperature is lower than 0°C. Icing means, the moisture contained in the surrounding environment and inside the relay freezes when the ambient temperature falls below the freezing point. The icing causes the sticking of movable portion, the operation delay and the contact conduction failure etc. Panasonic Corporation does not guarantee the failures caused by the icing. The heat conduction by the equipment may accelerate the cooling of relay itself and the icing may occur. Icing condition is changed by ambient environment, please make sure to confirm no icing in the worst condition of the actual usage. 4. Low-temperature, low-humidity atmosphere; If the relay is exposed to a low-temperature, low-humidity atmosphere for a long time, its plastic parts may become brittle and fragile. 5. Storage Do not keep under high-temperature and high-humidity.

In its final breakdown mode, it may lose the ability to provide the proper switch-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 switch-off ability, there is a possibility that burning may spread to surrounding parts, so configure the layout so that the power is turned off within one second. The contacts of the relay are polarized, so follow the connection schematic when connecting the contacts.  e careful that foreign matter and oils and fats kind don’t stick B 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. • Nominal cross-sectional area: Min. 2 mm2 As a guide, the insertion strength of the plug-in terminal into the relay tab terminal should be 40 to 80 N. Please select a plug-in terminal (flat connection terminal) which comply with JIS C2809-1999. • Plate thickness 0.8 mm and #250 tab terminal Other cautions for use 1. Please make sure to contact our company when the product is used not in accordance with its specifications. Your nearest sales office will review the required specification from your company and perform confirmation tests in actual condition as needed. Please check “Automotive relay user’s guide” for use of relays. 2. When the voltage is applied to the relay coil beyond the max. allowable voltage range, the relay operation cannot be assured. Additionally the ambient temperature and condition of your application should be considered under the worst condition of the actual usage because they may change the relay operate and release voltage. Note: It is not allowed to apply the continuous maximum voltage to the coil.In order to obtain the specified performance, please apply the rated voltage. 3. If it includes ripple, the ripple factor should be max. 5%. In addition, do not have a parallel connection with diode for the purpose of coil surge absorber. If only diode is connected in parallel to the relay coil, break performance of relay cannot be assured because contact release speed becomes slower. So do not use such a circuit. Instead of diode, a Varistor or Zener diode (ZD) when clamp voltage is 1.5 times larger than the rated voltage (Min. 18 V for the rated 12 V-relay), shall be used for the absorber. Ex.1 When Varistor is used Recommended Varistor; Energy capability: Min 1 J (However, please set up the value with consideration of the worst value in use condition.) Varistor Voltage: Min. 18 V at 12 V DC Ex.2 When Zener diode (circuit) is used [1] 12V Relay coil ＺＤ18V D ZD18V+ Diode operating voltage Clamp voltage [2] 12V 30V－12V=18V Clamp voltage ＺＤ30V   4. Lifetime is specified under the standard test conditions in JIS C 5442. (temperature 15°C to 35°C, humidity 25% RH to 75% 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 electrical life would be shortened. We can not guarantee the relay's quality in case the relay is operated without load current. (Dry switching)   5. If the relay is dropped, it should not be used again.   6. This relay cannot be used for switching with AC load.   7 Please check the internal connection diagram in the catalog or specification, and connect the terminals correctly. If any wrong connection is made, it may cause circuit damage by unexpected malfunction, abnormal heat, fire, and so on.   8. Please check the insulation distance between each terminal and ground.   9. Please perform evaluation under the worst case condition in actual use when new component is adopted and when there is a change of actual use condition in order to enhance the reliability in actual use. 10. Please absolutely avoid the ultrasonic and high frequency vibration to the relay that adversely affects its performance. 11. Minimum switching load is the lower limit switching current under the micro-load. When the relay is used below minimum switching load, reliability becomes lower. Please use the relay beyond minimum switching load. Additionally, minimum switching load is changed by coil drive circuit, type of load, switching frequency and environment condition. So please confirm the reliability with actual load under the assumed actual environment.

The relay should not be installed near strong magnetic fields (transformers, magnets, etc.) and should not be installed near heat source. 13. If the several relays are mounted closely or a heatgeneration object is close to the relay, it may cause troubles the abnormal temperature-rise and the short insulation distance terminals outside of the relay so please assure the evaluation of the relay under the actual worst condition. 14. After that the relay has been applied with the rated voltage and current to the coil continuously and then the relay is once switched off and switched on immediately, the relay coil resistance may be increased due to the coil temperature increase. This will result in higher operate voltage and the value will surpass the rated operate voltage value. In order to avoid this failure, the following countermeasures are recommended. - decrease of the load current - restriction of time to apply voltage - restriction of operating ambient temperature, etc. 15. If an inductive load (L/R > 1 ms) is applied, add surge protection in parallel with the inductive load. If this is not done, the electrical life will be shortened and cut-off failure may occur. 16. 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 15 A. The relay may have a contact welding without such countermeasure. 17. Use the suitable wire or bus bar according to the current. If the wire diameter is thin, maximum allowable contact current cannot be assured. Ex.) Carrying current; 10 A : diameter of 2 mm2 (minimum) (for wire at the load side) 18. Take care to disconnect from the power supply when wiring. 19. The relay satisfies water resistance level of JIS D0203 R2. Please take any countermeasures additionally if it is installed in the place where higher water resistance 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) may be adhered to this product. 21. Be careful that oils and foreign matter do not stick to the main terminal part because it is likely to cause a terminal part to give off unusual heat. 22. Do not make additional manufacturing upon the relay housing. 23. Maximum overcurrent value in this specification is limited as single operation only. In the case of multiple operation, this relay may cause malfunction by heating. So, please confirm the temperature / operation using your application. In the case of multiple operation, please stop applying the over current to secure the relay’s temperature under the maximum ambient temperature. 24. When applying current which includes precipitous changes or ripple, the relay may generate buzzing sound. Therefore, please confirm with the actual load.
