Section 2 Installation Mounting and Removing S800 I/O Units

3BSE056248 21

To mount the FCI, ModuleBus Modem or MTU, place it on the top edge of the

DIN rail, release the rail latch with a flat blade screw driver and snap the bottom

mechanism into place. When the unit is in place on the DIN rail and in position, take

away the screw driver and the rail latch will fix the unit in position on the DIN rail.

Release the unit from the DIN rail in a similar way.

A flat blade screw driver can be used to release the latch to allow easier movement

along the DIN rail or removal of the unit (Figure 8).
