Installation and Wiring Chapter 3

System Assembly

The module can be attached to an adjacent controller, power supply, or I/O

module. For mounting instructions, see

Panel Mounting on page 50, or

DIN Rail Mounting on page 52.

To work with a system that is already mounted, see

Replace the Module within a

System on page 53.

Refer to the illustration when assembling the Compact I/O system.

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 as before.

8. Lock the end cap bus terminator (G).

ATTENTION: When attaching I/O modules, it is very important

that the bus connectors are securely locked together to provide

proper electrical connection.

IMPORTANT

A 1769-ECR right- or 1769-ECL left-end cap must be used to

terminate the end of the serial communication bus.
