1. Hold-down springs work in conjunction with hold-down spring anchors included with DIN rail sockets.
2. When mounting relays with a check button onto panel mount or PC board mount sockets, use the hold-down spring shown in parenthesis. Hold-down
springs for relays with check buttons are not available for SR2P-51.
3. For close mounting of panel mount or PC mount sockets, use hold-down clips rather than hold-down springs.
4. SFA-101, SFA-202 and SFA-302 come in pairs.

Safety Precautions
Installing the Marking Plate
Because of its removable structure, the marking plate may have fallen from
the socket or become loose in delivery. Make sure that the marking plate is
securely installed before starting operation. The marking plate protects the
conductive portion of the socket, located under the marking plate, by preventing metal fragments or pieces of wire from dropping inside. Should any such
fragments enter the socket, they may cause fire hazard, damage, or malfunction.

Safety Precautions
Turn off the power to the SU9Z-J5 jumper before starting installation,
removal, wiring, maintenance, or inspection of the jumper. Failure to turn
power off may cause an electrical shock or fire hazard.
To avoid a short circuit due to incorrect wiring, confirm which terminals are
connected to the jumper before beginning wiring.

Mounting Relay Holders
Snap-mount sockets are designed to mount on the BNDN-1000
mounting rail. The built-in mounting clip eliminates mounting hardware and reduces mounting time by 80%.
To mount see Figure 1. Place the end of the socket (end opposite of
mounting clip against the outer edge of the rail). Press the socket
down firmly until the clip snaps onto the mounting rail. To remove
see Figure 2. Pull out the mounting clip with a screwdriver, and lift
the socket.
For spacing between adjoining sockets, use the SA-406 DIN rail
spacer. Spacers are 0.195" wide. Spacing can be adjusted according to the number of spacers added. Spacers snap on and off easily
like snap-mount sockets.
To prevent side-to-side movement, use a BNL-5 end clip at each
end of every socket row.

Mounting Hold-Down Springs
Take the two anchor clips (horseshoe / U-shaped
piece) that come with the socket and insert into
the slits on both sides of the socket. Make sure the
raised notches on the anchor clip face into the
socket.
Mount directly onto panel boards in two alternate
positions: A and B (see Figure 1).
To mount the relay into the holder, hook the bottom
edge of the relay case (coil terminal side) onto the
relay holder (see Figure 2).
Push down until the relay snaps into place.
Plug relay into socket
Insert the open ends of the hold-down spring into
either the first or second hole of the anchor clip.
The relay-spring combination will determine which
hole should be used.
IDEC surface mount sockets (SH2B-02) are also designed to mount
individually or collectively on a flat surface without the use of a DIN
rail. Use the mounting screw between adjoining sockets and at the
outer ends of the row of sockets.
