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.

Protective Debris Strips

ESD Sticker

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 industrial enclosure (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.

ATTENTION

Vertical mounting is not recommended due to heat build-up considerations.

ATTENTION

NOTE

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.

Remove the ESD sticker to install expansion I/O modules. An end cap terminator (catalog numbers 1769-ECR or -ECL) or an extension cable (catalog numbers 1769-CRR1, -CRR3,

-CLL1, -CLL3, -CRL1, -CRL3) 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 eight I/O modules may be connected to the base.

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.

Table 7 DIN Rail Mounting Dimensions

54.7 mm (2.16 in.) DIN latch open

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 10. 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.

Publication 1764-IN001B-EN-P

12 MicroLogix™ 1500 Programmable Controller Base Units

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.

Mounting Template

MicroLogix™ 1500 Programmable Controller Base Units 13

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 10).

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.

Wire Requirements

Table 8 Wire Type Recommendation

Wire Type Wire Size (2 wire maximum per terminal

screw)

Solid Cu-90°C (194°F) #14 to #22 AWG Stranded Cu-90°C (194°F) #14 to #22 AWG

Wiring torque = 1.13 Nm (10 in-lb) rated; 1.3 Nm (12 in-lb) maximum

ATTENTION

Be careful when stripping wires. Wire fragments that fall into the controller could cause damage. Once wiring is 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.

Finger-Safe Cover

Publication 1764-IN001B-EN-P

MicroLogix™ 1500 Programmable Controller Base Units 15

Spade Lug Recommendation

The diameter of the terminal screw head is 5.5 mm (0.220 in.). The input and output terminals 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.

Finger-Safe Cover

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 lifetime 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.

Publication 1764-IN001B-EN-P

16 MicroLogix™ 1500 Programmable Controller Base Units

Grounding the Controller

ATTENTION

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.

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.
