Chapter 2 Install the 1769-L3x Controllers
To install a CompactFlash card, push the locking tab to
the right and insert the industrial CompactFlash card
into the socket on the front of the controller.
The label of the CompactFlash card faces toward the
left. Match the orientation arrow on the card with the
arrow on the front of the controller.
To remove the CompactFlash card, push the locking tab
away from the CompactFlash card and pull the
CompactFlash card from the socket.
Assemble the System
The controller can be attached to an adjacent I/O module or power supply before
or after mounting.
Refer to the illustration when installing a controller.
1. Disconnect line power.
2. Check that the lever of the adjacent module (A) is in the unlocked (fully
right) position.
3. Use the upper and lower tongue-and-groove slots (B) to secure the
modules together.
4. Move the module back along the tongue-and-groove slots until the bus
connectors line up with each other.
5. Use your fingers or a small screwdriver to push the module’s bus lever back
slightly to clear the positioning tab (C).
WARNING: The CompactLogix controller is not designed for removal and
insertion under power.
If you insert or remove the module while backplane power is on, an electrical arc
can occur. This could cause an explosion in hazardous location installations.
Be sure that power is removed or the area is nonhazardous before proceeding.
