5 NOTES 1. Special use of types: 2 ways can be considered if types are used as 1 coil latching types. (A) Reverse polarity is applied to the set coil of 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. position of 2a2b type S 2. Soldering operations should be accomplished as quick as possible; within 1 seconds at 25 C 482 F solder temperature or 3 seconds at 35 C 662 F. 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. CAUTIONS FOR USE Based on regulations regarding insulation distance, there is a restriction on samechannel load connections between terminals No. 2, 3 and 4, 5, as well as between No. 8, 9 and 1, 11. See the figure below for an example Between 2, 3 and 4, 5: different channels, therefore not possible Between 1, 11 and 8, 9: different channels, therefore not possible No good Between 2, 3 and 4, 5: same channels, therefore possible Between 1, 11 and 8, 9: same channels, therefore possible ood For Cautions for Use, see Relay Technical Information (see catalog). en_ds_6115_: 1384D 5
