NOTES
1. 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 one-half.

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.
