Important User Information
Solid state equipment has operational characteristics differing from those of electromechanical
equipment. Safety Guidelines for the Application, Installation and Maintenance of Solid State Controls
(publication SGI-1.1 available from your local Rockwell Automation sales office or online at
http://literature.rockwellautomation.com) describes some important differences between solid state
equipment and hard-wired electromechanical devices. Because of this difference, and also because of
the wide variety of uses for solid state equipment, all persons responsible for applying this equipment
must satisfy themselves that each intended application of this equipment is acceptable.
In no event will Rockwell Automation, Inc. be responsible or liable for indirect or consequential damages
resulting from the use or application of this equipment.

Environment and Enclosure
Prevent Electrostatic Discharge
ATTENTION 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:
•Industrial Automation Wiring and Grounding Guidelines, for additional
installation requirements, Allen-Bradley publication 1770-4.1.
•NEMA Standards publication 250 and IEC publication 60529, as
applicable, for explanations of the degrees of protection provided by
different types of enclosure.
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.

Publication 1769-IN020D-EN-P - October 2008
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.

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.
1. Remove the battery door by sliding it forward.
2. Insert the battery connector into the connector port.
The connector is keyed to be installed with the correct polarity.
3. Insert the battery into the battery port in the battery door.
ATTENTION The 1769-BA battery is the only battery you can use with the 1769-L32E and
1769-L35E controllers. The 1747-BA battery is not compatible with the
1769-L32E and 1769-L35E controllers and may cause problems.
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.

4. Slide the battery door back until it clicks into position.
Install a 1784-CF64 or 1784-CF128 CompactFlash Card (optional)
The optional industrial CompactFlash card provides nonvolatile memory for
a CompactLogix controller. The card is not required for controller operation.
TIP At the end of its life, the used battery should be collected
separately from any unsorted municipal waste and recycled.
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.

Follow these steps to install a CompactFlash card.
1. 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.
2. 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. For mounting instructions, see Ground the Wiring
on page 12 or Mount the Panel on page 13.
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.
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.
