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, 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.

WARNING:
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 inspection par les
autorités locales qualifiées 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 cet équipement inadapté à
une 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

ATTENTION: This equipment is intended for use in a Pollution

Degree 2 industrial environment, in overvoltage Category II
applications (as defined in IEC 60664-1), at altitudes up to 2000 m
(6562 ft) without derating.

This equipment is considered Group 1, Class A industrial
equipment according to IEC/CISPR 11. Without appropriate
precautions, there may be difficulties with electromagnetic
compatibility in residential and other environments due to
conducted and radiated disturbances.

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, Rockwell
Automation publication 1770-4.1
requirements.

• NEMA Standard 250 and IEC 60529, as applicable, for
explanations of the degrees of protection provided by different
types of enclosure.

Prevent Electrostatic Discharge

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.

Determine Module Slot Location

Install the module in any slot in the ControlLogix chassis. You can install
multiple 1756-EN2T modules in the same chassis. The following figure shows
chassis slot numbering in a four-slot chassis. Slot 0 is the first slot and is always

the leftmost slot in the rack.

ControlLogix EtherNet/IP Module 9

Set the Network Address

The module ships with the rotary switches set to 999 and BOOTP enabled. You
can set the network Internet Protocol (IP) address three ways.

• Use the rotary switches on the top of the module.

• Use a BOOTP server or Dynamic Host Configuration Protocol

(DHCP) server, such as Rockwell Automation BOOTP/DHCP.

• Use the Rockwell Automation RSLinx or RSLogix 5000 software.

The module reads the rotary switches first to determine if they are set to a valid
number for the last portion of the IP address. Valid numbers range from
001…254. When the switches are set to a valid number, the module’s IP address
is 192.168.1.xxx (where xxx represents the number set on the switches). The
module’s subnet mask is 255.255.255.0 and the gateway address is set to 0.0.0.0.
The module does not have a host name assigned, or use any Domain Name
System when using the rotary switch settings.
