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.

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.
EXPLOSION HAZARD
Do not disconnect equipment
unless power has been
removed or the area is known
to be nonhazardous.
Do not disconnect
connections to this

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.

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.
