Inserting and removing method
Inserting method: Insert the relay as
shown in Fig. 1 unit the rib of the relay
snaps into the clip of the socket.
Rib
Fig. 1
Removing method:
(1) Remove the relay straight from the
socket holding the shaded portion of the
relay as shown in Fig. 2.
Fig. 2
(2) When sockets are mounted in close
proximity, use a slotted screw driver as
shown in Fig. 3.

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.

2. Soldering operations should be accomplished as quick as possible; within 10
seconds at 250°C 482°F solder temperature or 3 seconds at 350°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 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.
