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.

The examples and diagrams in this manual are included solely for illustrative purposes. Because of the

many variables and requirements associated with any particular installation, Rockwell Automation, Inc.

cannot assume responsibility or liability for actual use based on the examples and diagrams.

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 not intended for use in residential environments and may not

provide adequate protection to radio communication services in such

environments.

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:

• 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 wriststrap.

• 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.

The following information applies when

operating this equipment in hazardous

locations:

Informations sur l'utilisation de cet équipement

en environnements dangereux:

Products marked "CL I, DIV 2, GP A, B, C, D" are suitable

for use in Class I Division 2 Groups A, B, C, D, Hazardous

Locations and nonhazardous locations only. Each product

is supplied with markings on the rating nameplate

indicating the hazardous location temperature code.

When combining products within a system, the most

adverse temperature code (lowest "T" number) may be

used to help determine the overall temperature code of

the system. Combinations of equipment in your system

are subject to investigation by the local Authority Having

Jurisdiction at the time of installation.

Les produits marqués "CL I, DIV 2, GP A, B, C, D" ne conviennent

qu'à une utilisation en environnements de Classe I Division 2

Groupes A, B, C, D dangereux et non dangereux. Chaque produit

est livré avec des marquages sur sa plaque d'identification qui

indiquent le code de température pour les environnements

dangereux. Lorsque plusieurs produits sont combinés dans un

système, le code de température le plus défavorable (code de

température le plus faible) peut être utilisé pour déterminer le

code de température global du système. Les combinaisons

d'équipements dans le système sont sujettes à inspection par

les autorités locales qualifiées au moment de l'installation.

About the Module

You can use this Series C module with DeviceNet and PROFIBUS adapters. If you are

using RSLogix 5000 software, version 11 or higher, you can also use the Series C modules

with ControlNet and Ethernet adapters.

This module collects serial data from industrial absolute-position encoding sensors that

use standard SSI protocol. You insert the module into a POINT I/O terminal base that

provides common power, communication, and wiring connections for the SSI sensors.

Use this diagram to identify the external features of the module.

Publication 1734-IN581E-EN-E - October 2015

Install the Mounting Base

To install the mounting base on the DIN rail, 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.

4. To remove the mounting base from the DIN rail, remove the module and use a

small bladed screwdriver to rotate the base locking screw to a vertical position.

This releases the locking mechanism.

5. Then lift straight up to remove.

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 referenced to the base.

1. Using a bladed screwdriver, 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.

3. Insert the module straight down into the mounting base.

4. Press to secure. The module locks into place.

Turn the keyswitch to align the number

with the notch. Position 3 is shown here.

Publication 1734-IN581E-EN-E - October 2015

Install the Removable Terminal Block

A removable terminal block (RTB) is supplied with your wiring base assembly. To remove,

pull up on the RTB handle. This allows the mounting base to be removed and replaced as

necessary without removing any of the wiring.

To reinsert the removable terminal block, proceed as follows:

1. Insert the end opposite the handle into the base unit. This end has a curved

section that engages with the wiring base.

2. Rotate the terminal block into the wiring base until it locks itself in place.

3. If an I/O module is installed, snap the RTB handle into place on the module.

Remove a Mounting Base

To remove a mounting base, you must remove any installed module, and the module

installed in the base to the right. Remove the removable terminal block, if wired.

1. Unlatch the RTB handle on the I/O module.

2. Pull on the RTB handle to remove the removable terminal block.

3. Press on the module lock on the top of the module.

4. Pull on the I/O module to remove from the base.

5. Repeat steps 1, 2, 3 and 4 for the module to the right.

6. Use a small bladed screwdriver to rotate the orange base locking screw to a

vertical position. This releases the locking mechanism.

7. Lift straight up to remove.

WARNING: When you connect or disconnect the Removable Terminal Block

(RTB) with field side power applied, 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.
