Module Installation
Compact I/O is suitable for use in an industrial environment when installed in
accordance with these instructions. Specifically, this equipment is intended for
use in clean, dry environm ents (Poll ution degr ee 2

ATTENTION:
circuits or semiconductors if you touch bus connector pins.
!
Follow these guidelines when you handle the module:
• Touch a grounded object to discharge static potential.
• Wear an approved wrist-strap grounding device.
• Do not touch the bus connector or connector pins.
• Do not touch circuit components inside the module.
• If available, use a static-safe work station.
• When not in use, keep the module in its static-shield box.
Remove Power
ATTENTION:
this module. When you remove or insert a module with power

applied, an electrical arc may occur. An electrical arc can cause
personal injury or property damage by:
• sending an erroneous signal to your system’s field devices,
• causing an explosion in a hazardous environment
Electrical arcing causes excessive wear to contacts on both the
module and its mating connector. Worn contacts may create
electrical resistance.
Electrostatic discharge can damage integrated

1.Pollution Degree 2 is an environment where, normally, only non-conduct ive pollution
occurs except that occasionally a temporary conductivity caused by condensation shall
be expected.
2.Over Voltage Category II is the load level section of the electrical distribution system. At
this level transient voltages are controlled and do not exceed the impulse voltage
capability of the product’s insulation.
3.Pollution Degree 2 and Over Voltage Category II are International Electrotechnical
Commission (IEC) designations.

System Assembly
The module can be attached to the con troller o r a n adjacent I /O mod ule before or
after mounting. For mounting instructions, see “Panel Mounting” on page 5, or
“DIN Rail Mounting” on page 6. To work with a system that is already mounted,
see “Replacing a Single Module within a System” on page 7.
The following procedure shows you how 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-g roo ve slot s (1) to s ecure the mod ule s
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). Use y our
fingers or a small screw driver.
6. To allow communication between the controller and module, move the bus
lever fully to the left (4) until it clicks. Ensure it is locked firmly in place.
ATTENTION: When attaching I/O modules, it is very
important that the bus connectors are securely locked
!
7. Attach an end cap terminator (5) to the last module in the system by using
the tongue-and-groove slots as before.
8. Lock the end cap bus terminator (6).
IMPORTANT: A 1769-ECR or 17 69-ECL righ t or lef t end cap mu st be used to
together to ensure proper electrical connection.

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.
Minimum Spacing
Maintain spacing from
enclosure walls,
wireways, adjacent
equipment, etc. Allow 50
mm (2 in.) of space on all
sides for adequate
ventilation, as shown:

Panel Mounting
Mount the module to a panel using two screws per module. Use M4 or #8
panhead screws. Mounting screws are required on every module.
Panel Mounting Using the Dimensional Template
For more than 2 modules: (number of modules - 1) X 35 mm (1.38 in.)
