Overview
Install your controller using these installation instructions.
!ATTENTION: Do not remove protective debris strips until after
the base and all other equipment in the panel near the base is
mounted and wiring is complete. Once wiring is complete,
remove protective debris strips and install processor unit. Failure
to remove strips before operating can cause overheating.
!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.
!ATTENTION: Electrostatic discharge can damage
semiconductor devices inside the base unit. Do not touch the
connector pins or other sensitive areas.

Mounting the Controller
General Considerations
Most applications require installation in an industrialenclosure (Pollution Degree
2) to reduce the effects of electrical interference (Over Voltage Category II) 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.
Note: Remove the ESD sticker to install expansion I/O modules. An end cap
terminator (catalog number 1769-ECR) must be used at the end of the
group of I/O modules attached to the MicroLogix 1500 Controller. The
end cap terminator is not provided with the base unit. A maximum of 8
I/O modules may be connected to the base.
!ATTENTION: Vertical mounting is not recommended due to
heat build-up 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 base or processor unit
could cause damage. Do not drill holes above a mounted
controller if the protective debris strips have been removed or the
processor has been installed.

Controller Spacing
The base unit is designed to be mounted horizontally, with the Compact™
expansion I/O extending to the right of the base unit. Allow 50 mm (2 in.) of
space on all sides for adequate ventilation, as shown below.

Using a DIN Rail
The base unit and expansion I/O DIN rail latches lock in the open position so that
an entire system can be easily attached to or removed from the DIN rail. The
maximum extension of the latch is 15 mm (0.67 in.) in the open position. A flat-
blade screw driver is required for removal of the base unit. The base can be
mounted to EN50022-35x7.5 or EN50022-35x15 DIN rails. DIN rail mounting
dimensions are shown below.
To install your base unit on the DIN rail:
1. Mount your DIN rail. (Make sure that the placement of the base unit on the
DIN rail meets the recommended spacing requirements, see “Controller
Spacing” on page 9. Refer to the mounting template from the inside back
cover of this document.)
2. Hook the top slot over the DIN rail.
3. While pressing the base unit down against the top of the rail, snap the
bottom of the base unit into position.
4. Leave the protective debris strip attached until you are finished wiring the
base unit and any other devices.

To remove your base unit from the DIN rail:
1. Place a flat-blade screwdriver in the DIN rail latch at the bottom of the base
unit.
2. Holding the base unit, pry downward on the latch until the latch locks in the
open position. This releases the base unit from the DIN rail.

Using Mounting Screws
Mount to panel using #8 or M4 screws.
To install your base unit using mounting screws:
1. Remove the mounting template from the inside back cover of this
document.
2. Secure the template to the mounting surface. (Make sure your base unit is
spaced properly, see “Controller Spacing” on page 9).
3. Drill holes through the template.
4. Remove the mounting template.
5. Mount the base unit.
6. Leave the protective debris strips attached until you are finished wiring the
base unit and any other devices.

complete, be sure the base unit is free of all metal fragments
before removing protective debris strips and installing the
processor unit. Failure to remove strips before operating can
cause overheating.

Wiring Recommendation
When wiring without spade lugs, keep the finger-safe covers in place. Loosen the
terminal screw and route the wires through the opening in the finger-safe cover.
Tighten the terminal screw making sure the pressure plate secures the wire.
Spade Lug Recommendation
The diameter of the terminal screw head is 5.5 mm (0.220 in.). The input and
outputterminals of the MicroLogix 1500 base unit are designed for the following
spade lugs. The terminals will accept a 6.35mm (0.25 in.) wide spade (standard
for #6 screw for up to 14 AWG) or a 4 mm (metric #4) fork terminal.
When using spade lugs, use a small, flat-blade screwdriver to pry the finger-safe
cover from the terminal blocks, then loosen the terminal screw.

Surge Suppression
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 base unit to the ground bus prior to connecting any
devices. Use AWG #14 wire. 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, see the
Industrial Automation Wiring and Grounding Guidelines publication 1770-4.1.
!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 lifetime of relay
contacts or damage transistor outputs. By using suppression, you
also reduce the effects ofvoltage transients causedby interrupting
the current to that inductive device, and prevent electrical noise
from radiating into system wiring.
!ATTENTION: All devices connected to the RS-232 channel
must be referenced to base unit ground or floating. Failure to
follow this procedure may result in property damage or personal
injury.

➀Scan-time dependant.
➁For dc voltage applications, the make/break ampere rating for relay contacts can be determined by
dividing 28 VA by the applied dc voltage. For example, 28 VA/48V dc = 0.58A. Fordc voltage
applications less than 48V, the make/break ratings for relay contacts cannot exceed 2A.
