Mounting Your Controller Horizontally
The controller should be mounted horizontally within an enclosure using either the
DIN rail or mounting screw option. Use the mounting template from the front of
this document to help you space and mount the controller properly.
Using a DIN Rail
To install your controller on the DIN rail:
1. Mount your DIN rail. (Make sure that the
placement of the controller on the DIN rail
meets the recommended spacing
requirements. Refer to the mounting template
from the back of this document.)
2. Hook the top slot over the DIN rail.
3. While pressing the controller against the rail,
snap the controller into position.
4. Leave the protective wrap attached until you
are finished wiring the controller.
ATTENTION
!
Be careful of metal chips when drilling mounting holes for
your controller. Drilled fragments that fall into the controller
could cause damage. Do not drill holes above a mounted
controller if the protective wrap is removed.

To remove your controller from the DIN
rail:
1. Place a screwdriver in the DIN rail latch at the
bottom of the controller.
2. Holding the controller, pry downward on the
latch until the controller is released from the
DIN rail.
Using Mounting Screws
To install your controller using
mounting screws:
1. Remove the mounting template from the
back of this document.
2. Secure the template to the mounting
surface. (Make sure your controller is
spaced properly.)
3. Drill holes through the template.
4. Remove the mounting template.
5. Mount the controller.
6. Leave the protective wrap attached until you are finished wiring the controller.
Mounting Your Controller Vertically
Your controller can also be mounted vertically within an enclosure using mounting
screws or a DIN rail. To insure the stability of your controller, we recommend
using mounting screws. For additional information, refer to the previous section.
To insure the controller's reliability, the following environmental specifications must
not be exceeded.

Wiring Your Controller
We recommend using either of these AMP (or equal) spade lugs: part number
53120-1, if using 22-16 AWG, or part number 53123-1, if using 16-14 AWG.
Wire Type: Wire Size: (2 wire maximum per terminal screw)
Solid #14 to #22 AWG
Stranded #16 to #22 AWG
IMPORTANT The diameter of the terminal screw head is 5.5 mm (0.220 in.).
The input and output terminals of the MicroLogix 1000 controller
are designed for the following spade lugs:

IMPORTANT If you use wires without lugs, make sure the wires are securely
captured by the pressure plate. This is particularly important at
the four end terminal positions where the pressure plate does not
touch the outside wall of the controller.
IMPORTANT Be careful when stripping wires. Wire fragments that fall into the
controller could cause damage. Remove the protective wrap after
wiring your controller. Failure to remove the wrap may cause the
controller to overheat.
IMPORTANT This symbol denotes a functional earth ground terminal
which provides a low impedance path between electrical

MicroLogix™ 1000 Programmable Controllers 15
Publication 1761-IN001C-EN-P - March 2008
Grounding Your Controller
In solid-state control systems, grounding helps limit the effects of noise due to
electromagnetic interference (EMI). Run the ground connection from the ground
screw of the controller (third screw from left on output terminal rung) to the
ground bus. Use the heaviest wire gauge listed for wiring your controller.
You must also provide an acceptable grounding path for each device in your
application. For more information on proper grounding guidelines, see the
Industrial Automation Wiring and Grounding Guidelines, (publication 1770-4.1).
ATTENTION
!
All devices connected to the user 24V power supply or to the
RS-232 channel must be referenced to chassis ground or
floating. Failure to follow this procedure may result in
property damage or personal injury.
Chassis ground, user 24V ground, and the RS-232 ground are
internally connected. You must connect the chassis ground
terminal screw to chassis ground prior to connecting any
devices.
On the 1761-L10BWB, -L10BXB, -L16BWB, -L16BBB,
-L16NWB, -L20BWB-5A, -L32BBB, and -L32BWB controllers,
the ground associated with the user supplied 24V DC input
power and chassis ground are internally connected.

Publication 1761-IN001C-EN-P - March 2008
Surge Suppression
Inductive load devices such as motor starters and solenoids require the use of some
type of surge suppression to protect the controller output contacts. Switching
inductive loads without surge suppression can significantly reduce the life
expectancy of relay contacts. By adding a suppression device directly across the
coil of inductive devices, you prolong the life of the output circuits. You also
reduce the effects of radiated voltage transients and prevent electrical noise from
radiating into system wiring and facility.
The following diagram shows an output with a suppression device. We
recommend that you locate the suppression device as close as possible to the load
device.
If you connect a micro controller FET output to an inductive load, we recommend
that you use an 1N4004 diode for surge suppression, as shown in the illustration on
page 17.

MicroLogix™ 1000 Programmable Controllers 17
Publication 1761-IN001C-EN-P - March 2008
Suitable surge suppression methods for inductive load devices include a varistor, an
RC network, or, for dc loads, a diode. These components must be appropriately
rated to suppress the switching transient characteristic of the particular inductive
device. See the table on page 18 for recommended suppressors.
As the following diagram illustrates, these surge suppression circuits connect
directly across the load device. This reduces arcing and damage of the output
contacts. (High transients can cause arcing that occurs when switching off an
inductive device.)
If you connect a micro controller triac output to control an inductive load, we
recommend that you use varistors to suppress noise. Choose a varistor that is
appropriate for the application. The suppressors we recommend for triac outputs
when switching 120V ac inductive loads are a Harris MOV, part number V175
LA10A, or an Allen-Bradley MOV, catalog number 599-K04 or 599-KA04. Consult
the varistor manufacturer's data sheet when selecting a varistor for your application.
For inductive dc load devices, a diode is suitable. A 1N4004 diode is acceptable for
most applications. A surge suppressor can also be used. See the table on page 18
for recommended suppressors.
