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.

18) not switch the contacts without any load the contact
resistance may become increased rapidly. Care must exercised when the relay be
used stored high ambient temperature.g^î.
13) the power turned off and then immediately after
applying the rated voltage (current) continuously the

The relay might have contact welding without such
countermeasure.
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.
8) Take care avoid cross connections they may cause
malfunctions overheating. 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).
5) When applying current which includes precipitous changes
or ripple, the relay may generate buzzing sound.en.
23) For shutoff these contact polarity, but confirm the
electric life using the actual load. 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.
For coil surge absorption, please use zener diode or
varistor, etc. the contact
terminals were connected with opposite pole, the electric life
would shorter.yo'îa.
This causes the pick-up voltage rise, and possibly exceed
the rated pick-up voltage.
2) Additionally the ambient temperature and condition for your
application should considered because pick-up and drop
out voltage will changed.
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.5 times or
more (at least for rated type) the rated operation
voltage.
6) the relay used while exceeding the coil rating, contact
rating cycle lifetime, this may result the risk of
overheating.
22) not make additional manufacturing upon the relay
housing. Cautions for use
1) Regarding cautions for use and explanation technical
terms, please refer our “Relay Technical Information”. Please avoid
such usage. this not done, the electrical life will decrease and
cut-off failure may occur.
If only diode connected parallel with the relay coil, the
contact opening velocity will become slow and sufficient
cutoff performance cannot guaranteed. Therefore,
please confirm with the actual load. Check lifetime
under the actual condition.
10) Avoid mounting the relay strong magnetic fields (near a
transformer magnet) close object that radiates
heat.
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. (temperature 35°C 95°F, humidity
