Overview

MicroLogix 1100 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).

(3)

Install your controller using these installation instructions.

(1)

) and with circuits not exceeding Over Voltage

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.

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

(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.

Hazardous Location Considerations

This equipment is suitable for use in Class I, Division 2, Groups A, B, C, D or non-hazardous
locations only. The following WARNING statement applies to use in hazardous locations.

Publication 1763-IN001C-EN-P - June 2015

WARNING

EXPLOSION HAZARD

• Substitution of components may impair suitability for Class I, Division 2.

• Do not replace components or disconnect equipment unless power has been

switched off.

• Do not connect or disconnect components unless power has been switched off.

• This product must be installed in an enclosure. All cables connected to the

product must remain in the enclosure or be protected by conduit or other means.

• All wiring must comply with N.E.C. article 501-10(b).

• The interior of the enclosure must be accessible only by the use of a tool.

• For applicable equipment (for example, relay modules), exposure to some

chemicals may degrade the sealing properties of the materials used in these
devices:

– Relays, epoxy

9

It is recommended that you periodically inspect these devices for any degradation
of properties and replace the module if degradation is found.

ATTENTION

Use only the following communication cables in Class I, Division 2 hazardous locations.

UNSUPPORTED CONNECTION

Do not connect a MicroLogix 1100 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 1100 and/or the controller itself. Communication pins
used for RS-485 communications are alternately used for 24V power on the other
MicroLogix controllers.

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.

Vertical mounting is not supported 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.

closed

1. Mount your DIN rail. (Make sure that the placement of the controller on the DIN rail
meets the recommended spacing requirements. See Controller Spacing on page 12.
Refer to the mounting template inside the back cover of this document.)

2. If it is open, close the DIN latch.

3. Hook the top slot over the DIN rail.

4. While pressing the controller down against the top of the rail, snap the bottom of the

controller into position.

5. Leave the protective debris strip attached until you are finished wiring the controller
and any other devices.

Follow these steps to remove your controller from the DIN rail.

13

1. Place a flat-blade screwdriver in the DIN rail latch at the bottom of the controller.

2. Holding the controller, pry downward on the latch until the latch locks in the open

position.

3. Repeat steps 1 and 2 for the second DIN rail latch.

4. Unhook the top of the DIN rail slot from the rail.
