Electrostatic Discharge
Compact High-density Analog Current Input Module 3
ATTENTION
Electrostatic discharge can damage integrated circuits or
semiconductors if you touch bus connector pins. Follow these
guidelines when you handle the module:
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:
Electrical arcing causes excessive wear to contacts on both the module
and its mating connector. Worn contacts may create electrical
resistance.
• 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.
• Use a static-safe work station, if available.
• Keep the module in its static-shield box when not in use.
• sending an erroneous signal to your system’s field devices, causing
unintended machine motion.
• causing an explosion in a hazardous environment.

(1) Pollution Degree 2 is an environment where, normally, only non-conductive pollution occurs except that occasionally a
temporary conductivity caused by condensation is 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.

1. Add the module to the 1769 system.
You can add the module before or after mounting.
2. Mount Expansion I/O.
• Panel mount
• DIN-rail mount
3. Make field wiring connections.
4. Configure the module.
This publication describes these steps in detail.
Adding the Module to the 1769 System
Attach the module to the controller or an adjacent I/O module before or after
mounting. For mounting instructions, see Use the Dimensional Template
the Module to a DIN Rail. To work with a system that is already mounted, see
Replace a Single Module Within a System

Assemble the 1769 System
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, making 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 be sure of proper electrical connection.
Securely locking together the bus connectors is required for use in
hazardous locations.
For more information on hazardous locations see page 4
.
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
You must use a 1769-ECR or 1769-ECL right or left end cap to terminate
the end of the serial communication bus. An I/O configuration fault will
occur if an end cap is not used.
Replace a Single Module Within a System
The module can be replaced while the system is mounted to a panel or DIN rail.
1. Remove power.
See Remove Power
2. Remove the upper and lower mounting screws from the module or open the
DIN latches using a flat-blade or Phillips screwdriver.
3. Move the bus lever to the right to disconnect or 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 is disconnected from
the bus and that both mounting screws are removed or DIN latches opened.
TIP
on page 3.
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. Be sure that the bus lever on the module and on the right-side adjacent
module are in the unlocked (fully right) position before installing the
replacement module.
7. Slide the replacement module into the open slot.
8. Connect the modules 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.

Mounting Expansion I/O
Compact High-density Analog Current Input Module 9
ATTENTION
During panel or DIN rail mounting of all devices, be sure that all debris,
that is, metal chips or wire strands, is kept from falling into the module.
Debris that falls into the module could cause damage when cycling
power.
Minimum Spacing
Maintain spacing from enclosure walls, wireways, or adjacent equipment. Allow
50 mm (2 in.) of space on all sides for adequate ventilation, as shown.
