Publication 1769-IN030B-EN-P - October 2010
Refer to the illustration when assembling the Compact I/O system. See page
6 for a description
of the module.
1. Disconnect the power.
2. Check that the bus lever of the 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 (C)
line up with each other.
5. Use your fingers or a small screwdriver to push the bus lever back slightly to clear the
positioning tab (D).
6. Move the module’s bus lever fully to the left (E) until it clicks, making sure it’s locked
firmly in place.
7. Attach an end cap terminator (F) to the last module in the system by using the
tongue-and-groove slots.
8. Lock the end cap bus terminator (G).
ATTENTION: When attaching I/O modules, it’s very important that the bus
connectors are securely locked together to provide proper electrical connection.
A 1769-ECR or 1769-ECL right or left end cap must be used to terminate the end
of the Compact I/O module.
