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

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.

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.
