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://www.ab.com/manuals/gi) 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.

Publication 1762-IN006C-EN-P - September 2009

Overview

MicroLogix™ 1200 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 to 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 is 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.

AVERTISSEMENT

Publication 1762-IN006C-EN-P - September 2009

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

Vertical mounting is not recommended 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.
