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
Category II

(2)

(IEC 60664-1).

Publication 1762-IN006C-EN-P - September 2009

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.

Electrostatic discharge can damage semiconductor devices
inside the controller. Do not touch the connector pins or other
sensitive areas.

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.

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.

Pollution Degree 2 and Over Voltage Category II are International Electrotechnical Commission (IEC) designations.

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.

Publication 1762-IN006C-EN-P - September 2009

Vertical mounting is not recommended due to thermal
considerations.

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.
