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.

Publication 1756-IN582A-EN-P - August 2003
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.

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

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.

Publication 1756-IN582A-EN-P - August 2003
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.

1. Strip 7/16 inch (11mm) maximum
length of wire.
2. Insert the screwdriver into the
inner hole of the RTB.
3. Insert the wire into the
open terminal and
remove the screwdriver.
1. Strip 3/8 inch (9.5mm) maximum

Daisy chain to
other RTBs
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
e
4. Do not physically connect more than two wires to a single RTB terminal.
