Special use of 2 coil latching types: 2 ways can be considered if 2 coil latching types are used as 1 coil latching types. (A) Reverse polarity is applied to the set coil of 2 coil latching type. (B) By shorting terminals 12 and 7, apply plus to 1, minus to 6 at set and plus to 6, minus to 1 at reset. Applied coil voltage should be the same as the nominal. Operating power will be reduced to onehalf. Reset position of 2a2b type - 1 12 2 3 4 5 11 10 9 8 6 2. Soldering operations should be accomplished as quick as possible; within 10 seconds at 250C 482F solder temperature or 3 seconds at 350C 662F. The header portion being sealed with epoxy resin, undue subjection to heat may cause loss of seal. Solder should not be permitted to remain on the header. + 7 CAUTIONS FOR USE Based on regulations regarding insulation distance, there is a restriction on same-channel load connections between terminals No. 2, 3 and 4, 5, as well as between No. 8, 9 and 10, 11. See the figure below for an example. 2 3 11 10 4 5 9 8 11 O Between 2, 3 and 4, 5: different channels, therefore not possible 2 3 4 5 10 9 8 O Between 2, 3 and 4, 5: same channels, therefore possible O Between 10, 11 and 8, 9: different channels, therefore not possible O Between 10, 11 and 8, 9: same channels, therefore possible No good Good For Cautions for Use, see Relay Technical Information (see catalog). en_ds_61105_0000: 130804D 5
