Environment and Enclosure Information
ATTENTION Environment and Enclosure
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 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 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.
See NEMA Standards publication 250 and IEC publication 60529, as applicable, for
explanations of the degrees of protection provided by different types of enclosure. Also,
see the appropriate sections in this publication, as well as the Allen-Bradley publication
1770-4.1 ("Industrial Automation Wiring and Grounding Guidelines"), for additional
installation requirements pertaining to this equipment.

Before You Begin
Use this document as a guide for installing and powering-up your 1769-L31
CompactLogix controller. You should already be familiar with the system
components.
You must FLASH upgrade the firmware on your CompactLogix controller before
you can use it. The controller ships with firmware revision 1.x but must be
upgraded to match the version of RSLogix 5000 that you are using (e.g. if you are
using RSLogix 5000 V13, you must upgrade your CompactLogix controller firmware
to revision 13.x before using it. For more information on upgrading your
controller’s firmware, see page 18.
The following information applies when operating this
equipment in hazardous locations:
Informations sur l’utilisation de cet équipement en
environnements dangereux :
Products marked “CL I, DIV 2, GP A, B, C, D” are suitable for
use in Class I Division 2 Groups A, B, C, D, Hazardous
Locations and nonhazardous locations only. Each product is
supplied with markings on the rating nameplate indicating
the hazardous location temperature code. When combining
products within a system, the most adverse temperature
code (lowest “T” number) may be used to help determine the
overall temperature code of the system. Combinations of
equipment in your system are subject to investigation by the
local Authority Having Jurisdiction at the time of installation.
Les produits marqués "CL I, DIV 2, GP A, B, C, D" ne
conviennent qu’à une utilisation en environnements de
Classe I Division 2 Groupes A, B, C, D dangereux et non

System Planning
Consider the following when planning your CompactLogix system:
•The CompactLogix controller is always the left-most module in the system.
•The controller must be located within four modules of the system power
supply. Some I/O module’s may be located up to 8 modules away from the
power supply. See the documentation for your 1769 I/O modules for details.
•The 1769-L31 controller supports as many as 16 I/O modules in 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.

Publication 1769-IN069A-EN-P - March 2004
Connect the 1769-BA Battery
The controller is shipped with the 1769-BA battery packed separately. To connect
the battery, follow the procedure shown below.
1. Slide the battery door forward.
2. Insert the battery into the battery port. Insert the battery connector into the
connector port. The connector is keyed to engage in the correct polarity.
3. Slide the battery door back until it clicks into position.
ATTENTION The 1769-BA battery is the only battery you can use with the
1769-L31 controller. The 1747-BA battery is not compatible with
the 1769-L31 controller and may cause problems.
IMPORTANT Do not remove the plastic insulation covering the battery. The
insulation is necessary to protect the battery contacts.
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,
publication AG 5-4.

Publication 1769-IN069A-EN-P - March 2004
Install a 1784-CF64 Industrial CompactFlash Card (optional)
A 1784-CF64 Industrial CompactFlash card provides nonvolatile memory for a
CompactLogix controller. This is an optional feature and is not required to operate
the controller. Install the card as follows:
1. Push the locking tab to the right and insert the 1784-CF64 Industrial
CompactFlash card into the socket on the front of the controller.
The label of the CompactFlash card faces towards the left. Match the
orientation arrow on the card with the arrow on the front of the controller.
The CompactFlash card support removal and
insertion under power.
To remove the CompactFlash card, push the locking tab away from the
CompactFlash card and pull the CompactFlash card from the socket.
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 LED. 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 card
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. Repeated electrical arcing
causes excessive wear to contacts on
both the module and its mating
connector. Worn contacts may create
electrical resistance that can affect
module operation.

1769-L31 CompactLogix™ Controller 9
Publication 1769-IN069A-EN-P - March 2004
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 Panel mounting on page 12 or
DIN rail mounting on page 12.
The following procedure shows you how to install the controller in a
CompactLogix system.
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.
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. Repeated electrical arcing causes excessive
wear to contacts on both the module and its mating connector.
Worn contacts may create electrical resistance that can affect
module operation.

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. Ensure 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).
Mount the System
ATTENTION When attaching the controller, power supply, and I/O
modules, make sure the bus connectors are securely locked
together to ensure proper electrical connection.
WARNING If you connect or disconnect wiring while the field-side 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.
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 controller. Debris that falls into the controller could
cause damage while the controller is energized.
