Installation and Wiring Chapter 3
System Assembly The module can be attached to the controller or an adjacent I/O module before
or after mounting. For mounting instructions, see
Panel Mounting by Using the
Dimensional Template on page 29 , or DIN Rail Mounting on page 29 . To work
with a system that is already mounted, see Replace a Single Module within a
System on page 30 .
Follow this procedure to assemble the Compact I/O system.
1. Disconnect power.
2. Check that the bus lever of the module to be installed is in the unlocked
(fully right) position.
3. Use the upper and lower tongue-and-groove slots (1) to secure the modules
together (or to a controller).
4. Move the module back along the tongue-and-groove slots until the bus
connectors (2) line up with each other.
5. Push the bus lever back slightly to clear the positioning tab (3) by using
your fingers or a small screwdriver.
6. To allow communication between the controller and module, move the
bus lever fully to the left (4) until it clicks.
Be sure it is locked firmly in place.
7. Attach an end cap terminator (5) to the last module in the system by using
the tongue-and-groove slots as before.

IMPORTANT To reduce the effects of electrical noise, install the 1769-IT6 module at
least two slots away from the AC power supplies.
TIP If the module is being installed to the left of an existing module,
check that the right-side adjacent module’s bus lever is in the
unlocked (fully right) position.
ATTENTION: When attaching I/O modules, it is very important
that the bus connectors are securely locked together to be sure of
proper electrical connection.
