Use method
1. Both the SP relay 2c and 4c can be
mounted to the mounting slats.
2. Use the mounting slats either by attaching them directly to the chassis, or by
mounting with a DIN rail.
(A) When attaching directly to chassis
Use two M3 screws.
For the mounting pitch, refer to the specification diagram.
(B) When mounting on a DIN rail
Use a 35mm 1.378inch wide DIN rail
(DIN46277).
The mounting method should be as indicated in the diagram at right.

(1) First fit the arc shaped claw of the
mounting slat into the DIN rail.
(2) Press on the side as shown in the diagram below.
(3) Fit in the claw part on the opposite
side.
Precautions for use
When mounting to a DIN rail, use a commercially available fastening bracket if
there is a need to stop sliding of the
mounting slat in the rail direction.
Fig. 3
To remove the
relay, press down
the mounting slats
so the claws move
to the outside.
For Cautions for Use, see Relay Technical Information (Page 48 to 76).
