Panasonic is part of a large worldwide groupselling relays and associated switching products under different brand names in different territories.The conditions of use in some territories may differ from those customary in Europe. In particular there are often major differences in regard to national and international specifications, such as UL, CSA, VDE, SEV, EVE, SEMKO, etc. Thus, when considering contact loads as stated in this catalogue (e.g. 10 A, 30 VDC for the SP relay) its hould be understood that these values are not necessarily an absolute maximum but tested ratings. Mostly the stated value has been tested for a certain life expectancy as stated by the manufacturer or the respective test house. Thus, under different conditions, the stated “maximum” may, in practice, be safely exceeded.
5) When applying current which includes precipitous changes
or ripple, the relay may generate buzzing sound.
13) the power turned off and then immediately after
applying the rated voltage (current) continuously the
relay's coil and contact, the resistance the coil will
increase due rise the coil temperature.
16) Use the suitable wire for wire the load side according to
the current.
(Ex. the contact
terminals were connected with opposite pole, the electric life
would shorter.Z.îZD18V.g^î.
Ex. these circumstances, take
measures such reducing the load current, limiting the
duration current flow, and applying coil voltage higher
than the rated operating voltage (quick start). the wire diameter small, the maximum rated
contact current cannot guaranteed. Please take any countermeasures additionally if
it should installed the place where higher protection
level required.
20) not use this product 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 this product. Cautions for use
1) Regarding cautions for use and explanation technical
terms, please refer our “Relay Technical Information”.
14) case using capacitive load (C-load), please take a
countermeasure pre-charging the capacitive load so
that the inrush current will not surpass 60A.
8) Take care avoid cross connections they may cause
malfunctions overheating. Therefore,
please confirm with the actual load.
Especially, Contact terminals have polarity., that the clamp voltage reaches 1. When using varistor
Recommended Varistor; Maximum Energy: more than 1J
(However, please make settings using values that take into
consideration the worst case scenario. When using zener diode (circuit)

This causes the pick-up voltage rise, and possibly exceed
the rated pick-up voltage.en.
15) the relay used for inductive load load) such that
L/R 1ms, add surge protection parallel with the inductive
load.

4) Lifetime specified under the standard test conditions JIS
C 5442. Check lifetime
under the actual condition.
2) Additionally the ambient temperature and condition for your
application should considered because pick-up and drop
out voltage will changed. this not done, the electrical life will decrease and
cut-off failure may occur.
18) not switch the contacts without any load the contact
resistance may become increased rapidly.
11) the several relays are mounted closely heat-
generation object close the relay, take care check the
abnormal temperature-rise and the insulation distance
between the terminals outside the relay.(AEV)

7) general rule, not use relay has been dropped.
10) Avoid mounting the relay strong magnetic fields (near a
transformer magnet) close object that radiates
heat.

For Cautions for Use, see Relay Technical Information (page 166).
22) not make additional manufacturing upon the relay
housing.
For coil surge absorption, please use zener diode or
varistor, etc.er.
9) When the screws for fixing relay-body and for additional
terminal are tightened, should used within the range of
decided torque. (temperature 35°C 95°F, humidity
25%RH 85%RH)
Lifetime dependent the coil driving circuit, load type,
operation frequency and ambient conditions.
The relay might have contact welding without such
countermeasure.
23) For shutoff these contact polarity, but confirm the
electric life using the actual load.
19) The relay satisfies the protection level JIS 0203 (of
waterproof).)
Varistor voltage: For input, Min.yo'îa.
6) the relay used while exceeding the coil rating, contact
rating cycle lifetime, this may result the risk of
overheating. Please avoid
such usage.
21) careful that foreign matter and oils and fats kind don't
stick the main terminal parts because likely cause
terminal parts give off unusual heat.
3) includes ripple, the ripple factor should less than 5%.5 times or
more (at least for rated type) the rated operation
voltage. Care must exercised when the relay be
used stored high ambient temperature.
If only diode connected parallel with the relay coil, the
contact opening velocity will become slow and sufficient
cutoff performance cannot guaranteed.) Carrying current; 60A: diameter 15mm2 more
17) Take care disconnect the power supply when wiring.
12) The relay contacts are encapsulated inert gas
