FIXING AND REMOVAL METHOD
1. Match the direction of relay
and socket.
2. Both ends of the relay are to
be secured firmly so that the
socket hooks on the top sur-
face of the relay.
3. Remove the relay, applying
force in the direction shown
below.
4. In case there is not enough
space to grasp relay with fin-
gers, use screwdrivers in the
way shown below.

NOTES
1. Phase synchronization of AC-load
Ry

Vin
In case of switching the contact synchro-
nized with phase of load voltage, the life of
contact might be shorter or contact failure
might be caused. Please confirm this
matter in the actual system in this case. If

2. Soldering should be done under the fol-
lowing conditions:
250°C 482°F within 10s
300°C 572°F within 5s
350°C 662°F within 3s
For Cautions for Use, see Relay Technical Information (Page 48 to 76).
