Compact™ Individually Isolated 120V ac Input Module 5 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” on page 6, or “DIN Rail Mounting” on page 7. To work with a system that is already mounted, see “Replacing a Single Module within a System” on page 8. The following procedure shows you how to assemble the Compact I/O system. 3 4 2 1 6 1 5 1. Disconnect power. 2.

Compact™ Individually Isolated 120V ac Input Module IMPORTANT: A 1769-ECR or 1769-ECL right or left end cap must be used to terminate the end of the serial communication bus. Mounting Expansion I/O ! ATTENTION: During panel or DIN rail mounting of all devices, be sure that all debris (metal chips, wire strands, etc.) is kept from falling into the module. Debris that falls into the module could cause damage on power up.

Compact™ Individually Isolated 120V ac Input Module 7 Panel Mounting Procedure Using Modules as a Template The following procedure allows you to use the assembled modules as a template for drilling holes in the panel. If you have sophisticated panel mounting equipment, you can use the dimensional template provided on page 6. Due to module mounting hole tolerance, it is important to follow these procedures: 1. On a clean work surface, assemble no more than three modules. 2.

Compact™ Individually Isolated 120V ac Input Module Replacing a Single Module within a System The module can be replaced while the system is mounted to a panel (or DIN rail). Follow these steps in order: 1. Remove power. See important note on page 4. 2. On the module to be removed, remove the upper and lower mounting screws from the module (or open the DIN latches using a flat-blade or phillips style screwdriver). 3. Move the bus lever to the right to disconnect (unlock) the bus. 4.

Compact™ Individually Isolated 120V ac Input Module 9 Input Wiring Basic wiring1 of input devices to the 1769-IA8I is shown below. ! ATTENTION: Be careful when stripping wires. Wire fragments that fall into a module could cause damage at power up. Once wiring is complete, ensure the module is free of all metal fragments.
