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

Removing method: (1) Remove the relay straight from the socket holding the shaded portion of the relay as shown in Fig. 2.

(2) When sockets are mounted in close proximity, use a slotted screw driver as shown in Fig. 3. 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 onehalf.

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.
