Environment and Enclosure
Prevent Electrostatic Discharge
WARNING: This equipment is intended for use in a Pollution Degree 2 industrial
environment, in overvoltage Category II applications (as defined in IEC publication
60664-1), at altitudes up to 2000 meters (6562 ft) without derating.
This equipment is considered Group 1, Class A industrial equipment according to
IEC/CISPR Publication 11. Without appropriate precautions, there may be potential
difficulties ensuring electromagnetic compatibility in other environments due to
conducted as well as radiated disturbance.
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.
In addition to this publication, see the following:
•Industrial Automation Wiring and Grounding Guidelines, Allen-Bradley®
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
WARNING: 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.

Before You Begin
Consider the following when planning your CompactLogix system:
•The CompactLogix controller is always the leftmost module in the system.
•The controller must be within four modules of the system power supply. Some I/O
modules may be up to eight modules away from the power supply. See the
documentation for your 1769 I/O modules for details.
•The 1769-L32E controller supports as many as 16 I/O modules and the 1769-L35E
controller supports as many as 30 I/O modules. Both controllers can use a maximum of 3
I/O banks with 2 expansion cables.
•Each I/O bank requires its own power supply.
•Only one controller can be used in a CompactLogix system.
•A 1769-ECR right end cap or 1769-ECL left end cap is required to terminate the end of
the communication bus.
Parts List
These components are shipped with the controller.
You may also use these components with the controller.
Connect the 1769-BA Battery
The controller is shipped with the 1769-BA battery that is packed separately. To connect the
battery, follow this procedure.
Component Description
1769-BA battery
1747-KY controller key
If you want to Then use this component
Connect a device to the RS-232 port 1756-CP3 or 1747-CP3 serial cable
Connect a device to the EtherNet/IP port Standard Ethernet cable with RJ-45 connector

The connector is keyed to be installed with the correct polarity.
3. Insert the battery into the battery port in the battery door.
4. Slide the battery door back until it clicks into position.
WARNING: When you connect or disconnect the battery, 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.
For safety information on the handling of lithium batteries, including handling and
disposal of leaking batteries, see Guidelines for Handling Lithium Batteries
Technical Data, publication AG-5.4NOV04.
IMPORTANT
Do not remove the plastic insulation covering the battery. The insulation is
necessary to protect the battery contacts.

Publication 1769-IN020E-EN-P - December 2011
Install a CompactFlash Card (optional)
The optional industrial CompactFlash card provides nonvolatile memory for a CompactLogix
controller. The card is not required for controller operation.
To install a CompactFlash card, push the locking tab to the right
and insert the industrial CompactFlash card into the socket on the
front of the controller.
The label of the CompactFlash card faces toward the left. Match
the orientation arrow on the card with the arrow on the front of
the controller.
To remove the CompactFlash card, push the locking tab away
from the CompactFlash card and pull the CompactFlash card
from the socket.
Assemble the System
The controller can be attached to an adjacent I/O module or power supply before or after
mounting.
ATTENTION: Do not remove the CompactFlash card while the controller is reading
from or writing to the card, as indicated by a flashing green CF status indicator. This
could corrupt the data on the card or in the controller, as well as corrupt the latest
firmware in the controller.
WARNING: When you insert or remove the CompactFlash card while 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.
WARNING: The CompactLogix controller is not designed for removal and insertion
under power.
If 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.

Refer to the illustration when installing a controller.
1. Disconnect line power.
2. Check that the lever of the adjacent module (A) is in the unlocked (fully right) position.
3. Use the upper and lower tongue-and-groove slots (B) to secure the modules together.
4. Move the module back along the tongue-and-groove slots until the bus connectors line
up with each other.
5. Use your fingers or a small screwdriver to push the module’s bus lever back slightly to
clear the positioning tab (C).
6. Move the module’s bus lever fully to the left (D) until it clicks, being sure it is locked
firmly in place.
7. Attach an end-cap terminator (E) to the last module in the system by using the
tongue-and-groove slots as before.
8. Lock the end-cap bus terminator (F).
ATTENTION: When attaching the controller, power supply, and I/O modules, make
sure the bus connectors are securely locked together to be sure of proper electrical
connection.
This equipment is not resistant to sunlight or other sources of UV radiation.

Mount the System
Minimum Spacing
Maintain spacing from enclosure walls, wireways, and adjacent equipment. Allow 50 mm (2 in.)
of space on all sides, as shown. This provides ventilation and electrical isolation.
System Dimensions
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 controller.
Debris that falls into the controller could cause damage while the controller is
energized.
TIP
Compact I/O expansion cables have the same dimensions as the end caps.
Expansion cables can be used on either the right or left end. A 1769-ECR
right-end cap or 1769-ECL left-end cap terminates the end of the communication
bus.
