Important User Information

Solid-state equipment has operational characteristics differing from those of electromechanical

equipment. Safety Guidelines for the Application, Installation and Maintenance of Solid State Controls

(Publication SGI-1.1 available from your local Rockwell Automation sales office or online at

http://www.rockwellautomation.com/literature/) describes some important differences between

solid-state equipment and hard-wired electromechanical devices. Because of this difference, and also

because of the wide variety of uses for solid-state equipment, all persons responsible for applying this

equipment must satisfy themselves that each intended application of this equipment is acceptable.

In no event will Rockwell Automation, Inc. be responsible or liable for indirect or consequential damages

resulting from the use or application of this equipment.

Environment and Enclosure

Preventing Electrostatic Discharge

ATTENTION: This equipment is intended for use in a Pollution Degree 2

industrial environment, in overvoltage Category II applications (as defined in IEC

60664-1), at altitudes up to 2000 m (6562 ft) without derating.

This equipment is considered Group 1, Class A industrial equipment according

to IEC/CISPR 11. Without appropriate precautions, there may be difficulties

with electromagnetic compatibility in residential and other environments due to

conducted and radiated disturbances.

This equipment is supplied as open-type equipment. It must be mounted within

an enclosure that is suitably designed for those specific environmental

conditions that will be present and appropriately designed to prevent personal

injury resulting from accessibility to live parts. The enclosure must have

suitable flame-retardant properties to prevent or minimize the spread of flame,

complying with a flame spread rating of 5VA or be approved for the application

if nonmetallic. The interior of the enclosure must be accessible only by the use

of a tool. Subsequent sections of this publication may contain additional

information regarding specific enclosure type ratings that are required to

comply with certain product safety certifications.

In addition to this publication, see the following:

• Industrial Automation Wiring and Grounding Guidelines, publication

1770-4.1, for additional installation requirements.

• NEMA Standard 250 and IEC 60529, as applicable, for explanations of the

degrees of protection provided by enclosures.

ATTENTION: This equipment is sensitive to electrostatic discharge, which can

cause internal damage and affect normal operation. Follow these guidelines

when you handle this equipment:

• Touch a grounded object to discharge potential static.

• Wear an approved grounding wrist strap.

• Do not touch connectors or pins on component boards.

• Do not touch circuit components inside the equipment.

• Use a static-safe workstation, if available.

• Store the equipment in appropriate static-safe packaging when not in use.

Mount the I/O Base

To mount the I/O base on the DIN rail (Allen-Bradley part number 199-DR1; 46277-3;

EN50022), proceed as follows:

1. Position the mounting base vertically above the installed units (adapter, power

supply or existing module).

2. Slide the mounting base down allowing the interlocking side pieces to engage the

adjacent module or adapter.

3. Press firmly to seat the mounting base on the DIN rail. The mounting base snaps

into place.

ATTENTION: This product is grounded through the DIN rail to chassis ground.

Use zinc plated yellow-chromate steel DIN rail to assure proper grounding. The

use of other DIN rail materials (for example, aluminum or plastic) that can

corrode, oxidize, or are poor conductors, can result in improper or intermittent

grounding. Secure DIN rail to mounting surface approximately every 200 mm

(7.8 in.) and use end-anchors appropriately.

Install the Module

The module can be installed before or after base installation. Make sure that the mounting

base is correctly keyed before installing the module into the mounting base. In addition,

make sure the mounting base locking screw is positioned horizontal in reference to

the base.

1. Using a bladed screwdriver to rotate the keyswitch on the mounting base

clockwise until the number required for the type of module being installed aligns

with the notch in the base.

2. Make certain the DIN rail locking screw is in the horizontal position.

You cannot insert the module if the locking mechanism is unlocked.

WARNING: When you insert or remove the module while backplane power is

on, an electrical arc can occur. This could cause an explosion in hazardous

location installations.

Be sure that power is removed or the area is nonhazardous before proceeding.

Repeated electrical arcing causes excessive wear to contacts on both the

module and its mating connector. Worn contacts may create electrical

resistance that can affect module operation.

3. Insert the module straight down into the mounting base and press to secure.

The module locks into place.

Turn the keyswitch to align the

number with the notch.

Notch position 3 is shown.

Make sure the DIN rail locking

screw is in the horizontal position.
