The built-in mounting clip eliminates mounting hardBND-1000__ ware and reduces mounting time by 80%. . To mount see Figure 1. Place the end of the socket (end opposite of oeQnee? —_ Tl : mounting clip against the outer edge of the rail). Press the socket down firmly until the clip snaps onto the mounting rail. To remove **Figure 1** see Figure 2. Pull out the mounting clip with a screwdriver, and lift the socket. **Remove** For spacing between adjoining sockets, use the SA-406 DIN rail End Oi“ai 6 Snap-MountesSee I\, SA-406DIN Rail Spacer spacer. Spacers are 0.195" wide. Spacing can be adjusted accordSocket SFA-202 ing to the number of spacers added. Spacers snap on and off easily Hold-Down Spring like snap-mount sockets. **Figure 2** To prevent side-to-side movement, use a BNL-5 end clip at **each** end of every socket row. ## **Mounting Relay Holders** **==> picture [336 x 231] intentionally omitted <==** **----- Start of picture text -----**<br> F<br>RH-01 or -03<br>Mount directly onto panel boards in two alternate<br>positions: A and B (see Figure 1).<br>= ainoe<br>To mount the relay into the holder, hook the bottom<br>Figure 1 edge of the relay case (coil terminal side) onto the<br>relay holder (see Figure 2).<br>Push down until the relay snaps into place.<br>zB<br>~<br>138 dia hole 138 dia. hole<br>or #5-44<br>tapped hole<br>Figure 2<br>Sockets<br>**----- End of picture text -----**<br> ## **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.
