Electrostatic Discharge
Compact Combination Fast Analog I/O 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:
• 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.
Electrical arcing causes excessive wear to contacts on both the module and its
mating connector. Worn contacts may create electrical resistance.

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.

Install the 1769-IF4FXOF2F Module
Attach the module to the controller or an adjacent I/O module before or after
mounting. For mounting instructions, see Module to Panel Using the Dimensional
Template, or Mount Module to a DIN Rail. To work with a system that is already
mounted, see Replace a Single Module Within a 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.
Refer to Remove Power on page 3.
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
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.

Mount Expansion I/O
Compact Combination Fast Analog I/O 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.
