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.ab.com/manuals/gi) 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.

No patent liability is assumed by Rockwell Automation, Inc. with respect to use of

information, circuits, equipment, or software described in this manual.

Reproduction of the contents of this manual, in whole or in part, without written permission

of Rockwell Automation, Inc. is prohibited.

Throughout this manual we use notes to make you aware of safety considerations.

Environment and Enclosure

Prevent 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

publication 60664-1), at altitudes up to 2000 meters without derating.

This equipment is considered Group 1, Class A industrial equipment

according to IEC/CISPR Publication 11. Without appropriate precautions,

there may be potential difficulties ensuring electromagnetic compatibility in

other environments due to conducted as well as radiated disturbance.

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 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.

NOTE: See NEMA Standards publication 250 and IEC publication 60529, as

applicable, for explanations of the degrees of protection provided by

different types of enclosure. Also, see the appropriate sections in this

publication, as well as the Allen-Bradley publication 1770-4.1 ("Industrial

Automation Wiring and Grounding Guidelines"), for additional installation

requirements pertaining to this equipment.

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.

• If available, use a static-safe workstation.

When not in use, store the equipment in appropriate static-safe packaging.

Removal and Insertion Under Power

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.

North American Hazardous Location Approval

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.

The following information applies when

operating this equipment in hazardous

locations:

Identify the Module Components

You received the following components with your order:

• 1756-OV32E module

• Removable Terminal Block (RTB) door label

If you did not receive these components, contact your local

distributor Rockwell Automation sales office.

This module mounts in a 1756 chassis and uses a separately-ordered

RTB or a Bulletin 1492 Interface Module (IFM)

(1)

to connect all

field-side wiring. This module uses one of the following RTBs:

• 1756-TBCH 36-position Cage clamp RTB

• 1756-TBS6H 36-position Spring clamp RTB

Use an extended-depth cover (1756-TBE) for applications with heavy

gauge wiring or requiring additional routing space. When using an

IFM, consult the documentation that came with it to connect wiring.

Note the Power Requirements

This module receives power from the 1756 chassis power supply and

requires 2 sources of power from the ControlLogix backplane:

• 390mA at 5.1V dc

• 2mA at 24V dc

Add this current/power value (2.04W) to the requirements of all other

modules in the chassis to prevent overloading the power supply.

(1)

The Bulletin 1492 IFM may not be used in any application that requires agency certification of the

ControlLogix

system. Use of the IFM violates the UL, CSA and FM certifications of this product.

IMPORTANT

Before you install your module, you should:

• install and ground a 1756 chassis and power supply.

• order and receive an RTB or IFM, and its

components, for your application.

Publication

1756-IN582A-EN-P - August 2003

Install the Module

You can install or remove the module while chassis power is applied.

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.

1. Align the circuit board with the top and bottom chassis guides.

2. Slide the module into chassis until module locking tabs click.

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.

Key the Module and Removable Terminal Block/Interface Module

Use the wedge-shaped keying tabs and U-shaped keying bands to

prevent connecting the wrong wires to your module.

Key positions on the module that correspond to unkeyed positions

on the RTB. For example, if you key the first position on the module,

leave the first position on the RTB unkeyed.

1. To key the module, insert the U-shaped band, as shown.

2. Push the band until it snaps in place.

3. To key the RTB or IFM, insert the wedge-shaped tab with

rounded edge first, as shown.

4. Push the tab until it stops.

Reposition the tabs to rekey future module applications.

Wire the Removable Terminal Block

Wire the RTB with a 1/8 inch (3.2mm) maximum flat-bladed

screwdriver before installing it onto the module.

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

proceeding.

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.

1. When you daisy chain from a group to another RTB, always connect the daisy

chain to the terminal directly connected to the supply wire, as shown above.

2. This wiring example uses a single voltage source.

3. If separate power sources are used, do not exceed the specified isolation voltag

4. Do not physically connect more than two wires to a single RTB terminal.
