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.
The examples and diagrams in this manual are included solely for illustrative purposes. Because of the many
variables and requirements associated with any particular installation, Rockwell Automation, Inc. cannot
assume responsibility or liability for actual use based on the examples and diagrams.
No patent liability is assumed by Rockwell Automation, Inc. with respect to use of information, circuits,
equipment, or software described in this manual.
Reproduction of the contents of this manual, in whole or in part, without written permission of Rockwell
Automation, Inc., is prohibited.
Throughout this manual, when necessary, we use notes to make you aware of safety considerations.

Overview
MicroLogix 1100 controllers are suitable for use in an industrial environment when installed
in accordance with these instructions. Specifically, this equipment is intended for use in clean,
dry environments (Pollution degree 2(1)) and with circuits not exceeding Over Voltage
Category II(2) (IEC 60664-1).(3)
Install your controller using these installation instructions.
(1) Pollution Degree 2 is an environment where, normally, only non-conductive pollution occurs except that occasionally a
temporary conductivity caused by condensation shall be 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.
ATTENTION
Do not remove the protective debris strip until after the controller and all other equipment
in the panel near the controller are mounted and wiring is complete. Once wiring is
complete, remove protective debris strip. Failure to remove strip before operating can
cause overheating.
ATTENTION
Electrostatic discharge can damage semiconductor devices inside the controller. Do not
touch the connector pins or other sensitive areas.

WARNING
EXPLOSION HAZARD
•Substitution of components may impair suitability for Class I, Division 2.
•Do not replace components or disconnect equipment unless power has been
switched off.
•Do not connect or disconnect components unless power has been switched off.
•This product must be installed in an enclosure. All cables connected to the
product must remain in the enclosure or be protected by conduit or other means.
•All wiring must comply with N.E.C. article 501-10(b).
•The interior of the enclosure must be accessible only by the use of a tool.
•For applicable equipment (for example, relay modules), exposure to some
chemicals may degrade the sealing properties of the materials used in these
devices:
–Relays, epoxy
It is recommended that you periodically inspect these devices for any degradation
of properties and replace the module if degradation is found.

Publication 1763-IN001C-EN-P - June 2015
Use only the following communication cables in Class I, Division 2 hazardous locations.
Mounting the Controller
General Considerations
Most applications require installation in an industrial enclosure to reduce the effects of
electrical interference and environmental exposure. Locate your controller as far as possible
from power lines, load lines, and other sources of electrical noise such as hard-contact
switches, relays, and ac motor drives. For more information on proper grounding guidelines,
see the Industrial Automation Wiring and Grounding Guidelines, publication 1770-4.1.

ATTENTION
UNSUPPORTED CONNECTION
Do not connect a MicroLogix 1100 controller to another MicroLogix family controller
such as MicroLogix 1000, MicroLogix 1200, or MicroLogix 1500 using a 1761-CBL-AM00
(8-pin mini-DIN to 8-pin mini-DIN) cable or equivalent.
This type of connection will cause damage to the RS-232/485 communication port
(Channel 0) of the MicroLogix 1100 and/or the controller itself. Communication pins
used for RS-485 communications are alternately used for 24V power on the other
MicroLogix controllers.

Mounting Dimensions
ATTENTION
Vertical mounting is not supported due to thermal considerations.
ATTENTION
Be careful of metal chips when drilling mounting holes for your controller or other
equipment within the enclosure or panel. Drilled fragments that fall into the controller
could cause damage. Do not drill holes above a mounted controller if the protective
debris strips have been removed.

Controller Spacing
The controller mounts horizontally, with the expansion I/O extending to the right of the
controller. Allow 50 mm (2 in.) of space on all but the right side for adequate ventilation, as
shown below.
DIN Rail Mounting
The maximum extension of the latch is 14 mm (0.55 in.) in the open position. A flat-blade
screwdriver is required for removal of the controller. The controller can be mounted to
EN50022-35x7.5 or EN50022-35x15 DIN rails. DIN rail mounting dimensions are shown
below.
