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://literature.rockwellautomation.com) 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.

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.

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 1757-IN092E-EN-P - November 2007

Environment and Enclosure

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 m (6561 ft) 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 enclosure must have suitable

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

complying with a flame spread rating of 5VA, V2, V1, V0 (or

equivalent) if non-metallic. 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, for additional

installation requirements, Allen-Bradley publication 1770-4.1.

•NEMA Standards publication 250 and IEC publication 60529, as

applicable, for explanations of the degrees of protection provided by

different types of enclosure.

Prevent Electrostatic Discharge

Programmable Electronic Systems

Optical Ports

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.

ATTENTION Personnel responsible for the application of safety-related

Programmable Electronic Systems (PES) shall be aware of the safety

requirements in the application of the system and shall be trained in

using the system.

ATTENTION Under certain conditions, viewing the optical port may expose the eye

to hazard. When viewed under some conditions, the optical port may

expose the eye beyond the maximum permissible exposure

recommendations.

Determine Module Slot Location

Install the 1757-SRM module in the appropriate slot in the ControlLogix

chassis. Slot 0 is the first slot and is always the leftmost slot in the rack.

Installation Requirements

Before you assemble your redundant systems, make sure your redundant

system components are identical. Specifically, these items must match:

•primary and secondary (redundant) control chassis, with all modules

in the exact same order (slot for slot).

•firmware revisions of all module partners.

Chassis Type (series B) Recommended Slot Locations for 1757-SRM Module

1756-A4 1 or 2

1756-A7 4 or 5

1756-A10 5 or 6

1756-A13 4 or 5

1756-A17 5 or 6

IMPORTANT If the primary and secondary (redundant) systems are not

assembled identically, and are not comprised of modules with

matching firmware revisions, the 1757-SRM module cannot qualify

the secondary chassis to the primary chassis.
