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.

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.

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.
Follow these steps 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.).
Wire Type Wire Size (2 wire maximum per terminal)
1 wire per terminal 2 wire per terminal
Solid Cu-90 °C (194 °F) 12...20 AWG 16...20 AWG
Stranded Cu-90 °C (194 °F) 14...20 AWG 18...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.

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.).
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.

Publication 1763-IN001C-EN-P - June 2015
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 the 1763-L16BWA controller:
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 and 1763-L16DWD controllers:
The VDC NEUT or common terminal of the power supply is also connected to
chassis ground internally.

Publication 1763-IN001C-EN-P - June 2015
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.
Several specific steps can be taken to help reduce the effects of environmental noise on
analog signals:
