Publication 1763-IN001A-MU-P - May 2005
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(1)) and with 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 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.

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 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 Dimensions
ATTENTION Vertical mounting is not supported 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.

screws:
1. Remove the mounting template from inside the back cover of this document.
2. Secure the template to the mounting surface. (Make sure your controller is
spaced properly. See Controller Spacing on page 11.)
3. Drill holes through the template.
4. Remove the mounting
template.
5. Mount the controller.
6. Leave the protective debris
strip in place until you are
finished wiring the controller
and any other devices
Using the Battery
The MicroLogix 1100 controller is equipped with a replaceable battery. The Battery
Low indicator on the LCD display of the controller shows the status of the
replaceable battery. When the battery is low, the indicator is set (displayed as a
solid rectangle). This means that either the battery wire connector is disconnected,
or the battery may fail within 2 days if it is connected.
IMPORTANT The MicroLogix 1100 controller ships with the battery wire
connector connected.
Ensure that the battery wire connector is inserted into the
connector port if your application needs battery power. For
example, when using a real-time clock (RTC), or to store the
program in the controller’s memory for an extended period of
time while the power is removed.
Refer to the MicroLogix 1100 Programmable Controller User
Manual, publication 1763-UM001, for more information on
installation, handling, usage, storage, and disposal of the
battery.

Wire Requirements
Wiring Recommendation
The MicroLogix 1100 controllers have screw-cage clamps on the input and output
terminal blocks. With screw-cage clamp terminal blocks, there is no need to attach
additional hardware such as a spade lug to the wire, or use a finger-safe cover.
To wire the terminal block:
1. Strip the end of the wire.
The recommended length for the stripped end of the wire is 11.0 mm
(0.440 in.).
2. Insert it into an open clamp.
3. Using a small, flat-blade screwdriver, tighten the terminal screw. To ensure
that the wire conductor is secured inside the clamp, tighten it to the rated
torque, 0.56 Nm (5.0 in-lb).
The diameter of the terminal screw head is 5.5 mm (0.220 in.).
Wire Type Wire Size (2 wire maximum per terminal)
1 wire per terminal 2 wire per terminal
Solid Cu-90°C (194°F) #12 to #20 AWG #16 to #20 AWG
Stranded Cu-90°C (194°F) #14 to #20 AWG #18 to #20 AWG
Wiring torque = 0.56 Nm (5.0 in-lb) rated
ATTENTION Be careful when stripping wires. Wire fragments that fall into
the controller could cause damage. Once wiring is complete,
be sure the controller is free of all metal fragments before
removing the protective debris strip. Failure to remove the
strip before operating can cause overheating.

18 MicroLogix™ 1100 Programmable Controllers
Publication 1763-IN001A-MU-P - May 2005
Surge Suppression
ATTENTION Inductive load devices such as motor starters and solenoids
require the use of some type of surge suppression to protect
the controller output. Switching inductive loads without surge
suppression can significantly reduce the life of relay contacts
or damage transistor outputs. By using suppression, you also
reduce the effects of voltage transients caused by interrupting
the current to that inductive device, and prevent electrical
noise from radiating into system wiring. Refer to the
MicroLogix 1100 Programmable Controller User Manual,
publication 1763-UM001, for more information on surge
suppression.

MicroLogix™ 1100 Programmable Controllers 19
Publication 1763-IN001A-MU-P - May 2005
Grounding the Controller
In solid-state control systems, grounding and wire routing helps limit the effects of
noise due to electromagnetic interference (EMI). Run the ground connection from
the ground screw of the controller to the ground bus prior to connecting any
devices. Use AWG #14 wire. For AC-powered controllers, this connection must be
made for safety purposes.
You must also provide an acceptable grounding path for each device in your
application. For more information on proper grounding guidelines, refer to the
Industrial Automation Wiring and Grounding Guidelines, publication 1770-4.1.
ATTENTION All devices connected to the RS-232/485 communication port
must be referenced to controller ground, or be floating (not
referenced to a potential other than ground). Failure to follow
this procedure may result in property damage or personal
injury.
•For 1763-L16BWA controllers:
The COM of the sensor supply is also connected to chassis
ground internally. The 24V dc sensor power source
should not be used to power output circuits. It should
only be used to power input devices.
•For 1763-L16BBB controllers:
The VDC NEUT or common terminal of the power supply
is also connected to chassis ground internally.

20 MicroLogix™ 1100 Programmable Controllers
Publication 1763-IN001A-MU-P - May 2005
Wiring Your Analog Channels
Analog input circuits can monitor voltage signals and convert them to serial digital
data.
The controller does not provide loop power for analog inputs. Use a power supply
that matches the transmitter specifications as shown below.
Minimizing Electrical Noise on Analog Channels
Inputs on analog channels employ digital high-frequency filters that significantly
reduce the effects of electrical noise on input signals. However, because of the
variety of applications and environments where analog controllers are installed and
operated, it is impossible to ensure that all environmental noise will be removed by
the input filters.
