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.) Carrying current; 60A: diameter 15mm2 more
17) Take care disconnect the power supply when wiring.
(Ex.
19) The relay satisfies the protection level JIS 0203 (of
waterproof).
16) Use the suitable wire for wire the load side according to
the current.
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 adhered
to this product.
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. If
this not done, the electrical life will decrease and cut-off failure
may occur. the wire diameter small, the maximum rated
contact current cannot guaranteed.
22) not make additional manufacturing upon the relay
housing.(AEVS)
14) case using capacitive load (C-load), please take a
countermeasure pre-charging the capacitive load that
the inrush current will not surpass 60A. Please take any countermeasures additionally it
should installed the place where higher protection level is
required.
23) For shutoff these contact polarity, but confirm the
electric life using the actual load.
15) you are using inductive load load) such that L/R >
1ms, add surge protection parallel with the inductive load.
For Cautions for Use, see Relay Technical Information (page 166).
The relay might have contact welding without such
countermeasure
