About the End Caps/Terminators
The 1769 Compact I/O™ controllers, such as the 1769-L32E, require end caps. A 1769-ECR
right end cap, a 1769-ECRK right end cap, a 1769-ECLK left end cap, or a1769-ECL left end
cap terminates the end of the communication bus. Use this guide to install either end cap.

Summary of Changes
This publication contains new and updated information as indicated in the following table.
Topi c Page
Updated certification and warning information. Throughout
North American Hazardous Location Approval
The following information applies when operating
this equipment in hazardous locations.
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, Hazardou s Locati ons
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.
WARNIN G:
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 equipment unless power has
been removed or the area is known
to be nonhazardous. Secure any
external connections that mate to
this equipment by using screws,
sliding latches, threaded
connectors, or other means
provided with this product.
• Substitution of components may
impair suitability for Class I,
Division 2.
• If this product contains batteries,
they must only be changed in an
area known to be nonhazardous.
Informations sur l’utilisation de cet équipement en
environnements dangereux.
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 inspec tion par les
autorités locales quali fiées au moment de l'installation.
AVERTISSEMENT:
Risque d’Explosion –
• Couper le courant ou s'assurer que
l'environnement est classé non
dangereux avant de débrancher
l'équipement.
• Couper le courant ou s'assurer que
l'environnement est classé non
dangereux avant de débrancher les
connecteurs. Fixer tous les connecteurs
externes reliés à cet équipement à l'aide
de vis, loquets coulissants, connecteurs
filetés ou autres moyens fournis avec ce
produit.
• La substitution de composants peut
rendre ce t équipemen t inadapté à u ne
utilisation en environnement de Classe
I, Division 2.
• S'assurer que l'environnement est classé
non dangereux avant de changer les
piles.

Environment and Enclosure
ATT EN TI ON :
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
(6562 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 help prevent personal injury resulting from accessibility to live parts.
The enclosure must have suitable flame-retardant properties to help prevent or minimize the
spread of flame, complying with a flame spread rating of 5VA, V2, V1, V0 (or equivalent) 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, 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
ATT EN TI ON : 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.

European Hazardous Location Approval—1769-ECR and 1769-ECRK
The following applies to products marked , II 3 G. Such modules:
• Are Equipment Group II, Equipment Category 3, and comply with the Essential Health and Safety Requirements relating to the
design and construction of such equipment given in Annex II to Directive 2014/34/EU. See the EC Declaration of Conformity at
http://www.rockwellautomation.com/products/certification
• The type of protection used is ‘Ex nA IIC T4 Gc’ according to EN 60079-15.
• Comply to Standards: EN 60079-0:2012+A11:2013, EN 60079-15:2010, reference certific ate number DEMKO12ATEX1116807X.
• Modules are intended for use in areas in which explosive atmospheres caused by gases, vapors, mists, or air or dust mixtures are
unlikely to occur, or are likely to occur only infrequently and for short periods. Such locations correspond to Zone 2 classification
according to ATEX directive 2014/34/EU.
for details.
IEC Hazardous Location Approval—1769-ECR and 1769-ECRK
The following applies to products with IECEx certification. Such modules:
• Are intended for use in areas in which explosive atmospheres caused by gases, vapors, mists, or air are unlikely to occur, or are
likely
to occur only infrequently and for short periods. Such locations correspond to Zone 2 classification to IEC 60079-0.
• The type of protection is ‘Ex nA IIC T4 Gc’ according to IEC 60079-15.
• Comply to Standards: IEC 60079-0:6th edition, IEC-60079-15:4th Edition, reference IECEx certificate number IECEx UL 20.0078X.
WARNING: Special Conditions for Safe Use
• Equipment is not resistant to sunlight or other sources of UV radiation.
• Equipment shall be mounted in an ATEX/IECEx Zone 2 certified enclosure with a minimum
ingress protection rating of at least IP54 (as defined in EN/IEC 60529) and used in an
environment of not more than Pollution Degree 2 (as defined in EN/IEC 60664-1) when
applied in Zone 2 environments. The enclosure must be accessible only by the use of a tool.
• Equipment shall be used within its specified ratings defined by Rockwell Automation.
• Provision shall be made to prevent the rated voltage from being exceeded by transient
disturbances of more than 140% of the rated voltage when applied in Zone 2 environments.
• Equipment must be used only with ATEX/IECEx certified Rockwell Automation backplanes.
• Do not disconnect equipment unless power has been removed or the area is known to
be nonhazardous.
