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 environments (Pollution degree 2(1)) and to circuits not exceeding Over Voltage Category II(2) (IEC 60664-1).(3)

Prevent Electrostatic Discharge

	ATTENTION	Electrostatic discharge can damage integrated circuits or
		semiconductors if you touch bus connector pins or the
		terminal block. 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.

(1)Pollution Degree 2 is an environment where, normally, only non-conductive 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.

Remove Power

	ATTENTION	Remove power before removing or inserting 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 unintended machine motion

•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.

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.

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. Ensure 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.

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

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 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.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.

4.Drill and tap the mounting holes for the recommended M4 or #8 screw.

5.Place the modules back on the panel and check for proper hole alignment.

6.Attach the modules to the panel using the mounting screws.

NOTE	If mounting more modules, mount only the last one of
	this group and put the others aside. This reduces
	remounting time during drilling and tapping of the next
	group.

7. Repeat steps 1 to 6 for any remaining modules.

DIN Rail Mounting

The module can be mounted using the following DIN rails: 35 x 7.5 mm (EN 50 022 - 35 x 7.5) or 35 x 15 mm (EN 50 022 - 35 x 15).

Before mounting the module on a DIN rail, close the DIN rail latches. Press the DIN rail mounting area of the module against the DIN rail. The latches will momentarily open and lock into place.

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.On the right-side adjacent module, move its bus lever to the right (unlock) to disconnect it from the module to be removed.

5.Gently slide the disconnected module forward. If you feel excessive resistance, check that the module has been disconnected from the bus and that both mounting screws have been removed (or DIN latches opened).

NOTE	It may be necessary to rock the module slightly from front
	to back to remove it, or, in a panel-mounted system, to
	loosen the screws of adjacent modules.

6.Before installing the replacement module, be sure that the bus lever on the module to be installed, and on the right-side adjacent module are in the unlocked (fully right) position.

7.Slide the replacement module into the open slot.

8.Connect the modules together by locking (fully left) the bus levers on the replacement module and the right-side adjacent module.

9.Replace the mounting screws (or snap the module onto the DIN rail).
