13. Cautions for use
1) Regarding cautions for use and explanation of technical
terms, please refer to our “Automotive 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?cient 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.)
Varistor voltage: For 12 V DC input, Min. 18 V
Ex. 2: When using a zener diode (circuit)
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
?ow, 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?es 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’t
4) Lifetime is speci?ed 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.
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?rm the
electric life using the actual load.
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
ripple, the relay may generate buzzing sound. Therefore, please
con?rm 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 ?xing 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 ?elds (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.
