Environment and Enclosure

ATTENTION: This equipment is intended for use in a Pollution Degree 2 industrial environment, in overvoltage Category II applications (as defined in IEC 60664-1), at altitudes up to 2000 m (6562 ft) without derating.

This equipment is considered Group 1, Class A industrial equipment according to IEC/CISPR 11. Without appropriate precautions, there may be difficulties with electromagnetic compatibility in residential and other environments due to conducted and radiated disturbances.

This equipment is supplied as open-type equipment. It must be mounted within an enclosure that is suitably designed for those specific environmental conditions that will be present and appropriately designed to prevent personal injury resulting from accessibility to live parts. The enclosure must have suitable flame-retardant properties to prevent or minimize the spread of flame, complying with a flame spread rating of 5VA, V2, V1, V0 (or equivalent) if non-metallic. The interior of the enclosure must be accessible only by the use of a tool. Subsequent sections of this publication may contain additional information regarding specific enclosure type ratings that are required to comply with certain product safety certifications.

Besides this publication, see:

•Industrial Automation Wiring and Grounding Guidelines, publication 1770-4.1, for additional installation requirements, .

•NEMA Standards publication 250 and IEC publication 60529, as applicable, for explanations of the degrees of protection provided by different types of enclosure.

Prevent Electrostatic Discharge

ATTENTION: This equipment is sensitive to electrostatic discharge, which can cause internal damage and affect normal operation. Follow these guidelines when you handle this equipment:

•Touch a grounded object to discharge potential static.

•Wear an approved grounding wriststrap.

•Do not touch connectors or pins on component boards.

•Do not touch circuit components inside the equipment.

•Use a static-safe workstation, if available.

•Store the equipment in appropriate static-safe packaging when not in use.

Remove Power

WARNING: When you insert or remove the module while backplane power is on, an electrical arc can occur. This could cause an explosion in hazardous location installations.

Be sure that power is removed or the area is nonhazardous before proceeding. Repeated electrical arcing causes excessive wear to contacts on both the module and its mating connector. Worn contacts may create electrical resistance that can affect module operation.

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 8, or DIN Rail Mounting on page 9. To work with a system that is already mounted, see Replacing a Single Module within a

System on page 9.

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-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).

Use 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.

ATTENTION: When attaching I/O modules, it is very important that the bus connectors are securely locked together to ensure proper electrical connection.

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 1769-ECL right or left end cap must be used to terminate the end of the communication bus.

Mounting Expansion I/O

ATTENTION: During panel or DIN rail mounting of all devices, be sure that all debris (such as metal chips or wire strands) is kept from falling into the module. Debris that falls into the module could cause damage on power up.

ATTENTION: When used in a Class I, Division 2, hazardous location, this equipment must be mounted in a suitable enclosure with proper wiring method that complies with the governing electrical codes.

8 CompactLogix Isolated Analog Input Module

Grounding the Module

ATTENTION: This product is intended to be mounted to a well-grounded mounting surface such as a metal panel. Additional grounding connections from the power supply's mounting tabs or DIN rail (if used) are not required unless the mounting surface cannot be grounded. Refer to Industrial Automation Wiring and Grounding Guidelines, Rockwell Automation publication 1770-4.1, for additional information.

Minimum Spacing

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

Panel Mounting

Mount the module to a panel by using two screws per module. Use M4 or #8 panhead screws. Mounting screws are required on every module.

Panel Mounting Using the Dimensional Template

Spacing for single-wide modules 35 mm (1.378 in.).

l Mounting

Spacing for one-and-a-half-wide modules 52.5 mm (2.067 in.). Refer to host controller documentation for this dimension.

NOTE: Overall hole spacing tolerance: ±0.4 mm (0.016 in.).

Locate holes every 17.5 mm (0.689 in.) to allow for a mix of single-wide and one-and-a-half-wide modules (for example, the 1769-OA16 module).

Host Controller

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 8. Due to module mounting hole tolerance, it is important to follow this procedure.

1.On a clean work surface, assemble no more than three modules.

2.Using the assembled modules as a template, carefully mark the center of all module-mounting holes on the panel.

3.Return the assembled modules to the clean work surface, including any previously mounted modules.
