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.

9) When the screws for fixing relay-body and for additional
terminal are tightened, should used within the range of
decided torque.
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.
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) When applying current which includes precipitous changes
or ripple, the relay may generate buzzing sound. this not done, the electrical life will decrease and
cut-off failure may occur.
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.
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.
15) the relay used for inductive load load) such that
L/R 1ms, add surge protection parallel with the inductive

. Please take any countermeasures additionally if
it should installed the place where higher protection
level required. the contact
terminals were connected with opposite pole, the electric life
would shorter.
If only diode connected parallel with the relay coil, the
contact opening velocity will become slow and sufficient
cutoff performance cannot guaranteed. Check lifetime
under the actual condition. 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 relay might have contact welding without such
countermeasure.(AEV)
13. When using varistor

consideration the worst case scenario.yo'îa.
This causes the pick-up voltage rise, and possibly exceed

6) the relay used while exceeding the coil rating, contact

overheating. Cautions for use
1) Regarding cautions for use and explanation technical
terms, please refer our “Relay Technical Information”.er.
12) The relay contacts are encapsulated inert gas

For Cautions for Use, see Relay Technical Information (page 166).
Especially, Contact terminals have polarity.5 times or
more (at least for rated type) the rated operation
voltage.
2) Additionally the ambient temperature and condition for your
application should considered because pick-up and drop
out voltage will changed.
7) general rule, not use relay has been dropped.
16) Use the suitable wire for wire the load side according to
the current.
18) not switch the contacts without any load the contact
resistance may become increased rapidly.
19) The relay satisfies the protection level JIS 0203 (of

22) not make additional manufacturing upon the relay

17) Take care disconnect the power supply when wiring. Therefore,
please confirm with the actual load. Please avoid
such usage.
10) Avoid mounting the relay strong magnetic fields (near a
transformer magnet) close object that radiates

8) Take care avoid cross connections they may cause
malfunctions overheating.
20) not use this product such atmosphere where any kind
