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.

Environment and Enclosure
Preventing 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.
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.

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 dangereux. Chaque produit est livré avec des
marquages sur sa plaque d’identification qui
indiquent le code de température pour les
environnements dangereux. Lorsque plusieurs
produits sont combinés dans un système, le code de
température le plus défavorable (code de température
le plus faible) peut être utilisé pour déterminer le code
de température global du système. Les combinaisons
d’équipements dans le système sont sujettes à
inspection par les autorités locales qualifiées au
moment de l’installation.
WARNING
EXPLOSION HAZARD
•Do not disconnect while the
circuit is live or unless the area
is known to be free of ignitible
concentrations.
•Do not disconnect connections
to this equipment unless power
has been removed or the area is
known to be nonhazardous.
Secure any external connections
that mate to this equipment by
using screws, sliding latches,
threaded connectors, or other
means provided with this
product.
•Substitution of components may
impair suitability for Class I,
Division 2.
•Do not remove or replace lamps,
fuses or plug-in modules (as
applicable) unless power has
been disconnected or the area is
known to be free of ignitible
concentrations of flammable
gases or vapors.

Publication 1766-IN001D-EN-P - June 2015
Overview
MicroLogix 1400 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). AC powered products must be connected to the secondary of
an isolating transformer.
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 commissions (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.

UNSUPPORTED CONNECTION
Do not connect the Comm0 port on the MicroLogix 1400 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
