(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 and from the point of view of safety, consider installing a failsafe circuit in the device. also, in order to avoid increased contact resistance, do not operate when there is no switching load. 6. 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). for this reason, make sure the ambient operating temperature is between ?0 and 80 c ?0 and +176 f , and the ambient storage temperature is between ?0 and 85 c ?0 and +185 f . 7. do not disassemble the relay. please note that disassembling the relay will invalidate the warranty. 8. if the power is turned off and then immediately on after applying the rated v oltage (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 v oltage to rise, and possibly exceed the r ated 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. 9. coil operating power pure dc current should be applied to the coil. the wave form should be rectangular. if it includes ripple, the ripple f actor should be less than 5%. however, check the actual circuit since the characteristics may be slightly different. the power supply waveform supplied to the coil should be rectangular. 10. don? exceed maximum coil v oltage. exceeding maximum allowable coil voltage on continuous basis will damage the relay and could case failure. 11. ensure that the rated contacts v oltage and current values are not e xceeded. 12. the rated control capacity and life are given as general guides. the contact life is heavily in?enced by the type of load and other related conditions, and these factors must be k ept in consideration when using the relay. 13. main contact ratings in the ratings apply to when there is a resistive load. 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. 14. 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 f ollowing materials for connected harnesses and bus bars. 10a tm type: faston terminal for #187 tab terminal, 0.5 mm board thickness (jis c2809-1992 compliant, ?t type connection terminal) harness nominal cross-sectional area load input terminal: min. 2.0 mm 2 coil input terminal: min. 0.3 mm 2 60a and 80a types: min. 15mm 2 nominal cross sectional area 300a type: min. 100mm 2 nominal cross sectional area 15. use 40n to 70n of force as a guide to fasten the terminal connected to the 10a tm type. please use caution when inserting or removing the terminal as the relay tab terminal may cause injuly. 16. place the pc board mount type (10a pc board type) securely by hand soldering after attaching it using m4 screw. don? submerge assembled board in cleaning solvent or water. also, be careful not let ?x over?w up from the pc board or adhere to the base of the relay. recommended hand soldering conditions ?soldering iron: 30 to 60 w ?tip temperature: 400 c 752 f ?solder time: within approx. 5 seconds 17. make sure the power is turned off when wiring. 18. incorrect wiring may cause unexpected malfunction and failure. 19. regarding ac cutoff, although there is no contact polarity, generally it is thought that the electrical life will shorten due to cutoff in the reverse direction, compared to dc cutoff. con?m electrical life using actual load. in the case of dc cut-off, please note the contact polarity. 20. lead-free solder (tin, silver and copper) is used as pre-solder for the terminals of the pc board mount type (10a pc board type). 21. the warranted tensile strength of the female connector lead wire used f or connection that comes with the 80a and 300a connector type when attaching it to the relay body is 10n. av oid excessive tension as this is a cause of broken wires and damage. also, insert the female connector deeply and make sure the connection is secure.
