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.

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.

ATTENTION

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

(Channel 0) of the MicroLogix 1400 and/or the controller itself. Communication pins used

for RS-485 communications are alternately used for 24V power on the other MicroLogix

controllers.
