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 flow, and applying a coil voltage higher than the rated operating voltage (quick start). 10. If you are using an inductive load (L load) such that L/R > 1 ms, 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. 11. Be careful that foreign matter and oils and fats kind doesn’t stick to the main terminal part because it is likely to cause a terminal part to give off unusual heat. 12. Avoid excessive load applied to the terminal in case of installing such as a bus bar etc., because it might give bad influence to the opening and closing performance. Tighten each of the screws within the rated ranges given below. Main terminal (M6 screw): 6.0N·m to 8.0N·m Main unit mounting (M5 screw): 2.5N·m to 3.6N·m 13. Usage, transport and storage conditions Ambient temperature, humidity, and atmospheric pressure during usage, transport, and storage of the relay: 1) Temperature: –40 to +85°C –40 to +185°F 2) Humidity: 5 to 85% RH (Avoid freezing and condensation.) 3) Atmospheric pressure: 85 to 106 kPa Temperature and humidity range for usage, transport, and storage: Humidity, %R.H. ;;;;; ; ; ; ;;;;;;;;;;;;;;;;;; ;;;;;;;;;;;; ;;;;;;;;;;;; ;;;;;;;;;;;; ;;;;;;;;;;;; ;;;;;;;;;;;; ;;;;;;;;;;;; 1. To ensure proper operation, the voltage applied to the coil should be the rated operating voltage of the coil. Also, be aware that the pick-up and drop-out voltages will fluctuate depending on the ambient temperature and operating conditions. 2. Heat, smoke, and even a fire may occur if the relay is used in conditions outside of the allowable ranges for the coil ratings, contact ratings, operating cycle lifetime, and other specifications. Therefore, do not use the relay if these ratings are exceeded. 3. If the relay has been dropped, the appearance and characteristics should always be checked before use. 4. When using this relay for AC load switching, caution is required. Please contact us. 5. Make sure that the relay is wired correctly. Incorrect wiring may cause unexpected events or the generation of heat or flames. 6. We recommend you use a surge absorbing element with a clamp voltage of “Rating voltate x1.5: 18V/ 36V/54V” or more for the relay coil drive circuit as a means for relay coil surge absorption. Please avoid the use of diodes, capacitors and resistors because they lead to degradation in cut-off performance. 7. Avoid mounting the relay in strong magnetic fields (near a transformer or magnet) or close to an object that radiates heat. 8. Electrical life This relay is a high-voltage direct-current switch. In its final 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 configure the layout so that the power is turned off within one second. 85 Tolerance range (Avoid freezing when (Avoid used at temperatures condensation when lower than 0°C 32°F) used at temperatures higher than 0°C 32°F) 5 –40 –40 0 +32 Temperature, °C °F +85 +185 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) Freezing Condensation or other moisture may freeze on the relay when the temperatures is lower than 0°C 32°F. This causes problems such as sticking of movable parts or operational time lags. 6) 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.
