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.

Environment and Enclosure
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.

Preventing Electrostatic Discharge
European Hazardous Location Approval
European Zone 2 Certification (The following applies when the product
bears the EEx Marking)
This equipment is intended for use in potentially explosive atmospheres as
defined by European Union Directive 94/9/EC.
The LCIE (Laboratoire Central des Industries Electriques) certifies that this
equipment has been found to comply with the Essential Health and Safety
Requirements relating to the design and construction of Category 3
equipment intended for use in potentially explosive atmospheres, given in
Annex II to this Directive. The examination and test results are recorded in
confidential report No. 28 682 010.
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 work station.
•When not in use, store the equipment in
appropriate static-safe packaging.

Compliance with the Essential Health and Safety Requirements has been
assured by compliance with EN 50021.
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
IMPORTANT When using this equipment, consider the following:
•This equipment is not resistant to sunlight or other
sources of UV radiation.
•The secondary of a current transformer shall not be
open-circuited when applied in Class I, Zone 2
environments.
•Equipment of lesser Enclosure Type Rating must be
installed in an enclosure providing at least IP54
protection when applied in Class I, Zone 2
environments.
•This equipment shall be used within its specified
ratings defined by Allen-Bradley.
•Provision shall be made to prevent the rated voltage
from being exceeded by transient disturbances of
more than 40% when applied in Class I, Zone 2
environments.

Determine Module Slot Location
You can install the module in any slot in the ControlLogix chassis. You can
also install multiple 1756-EWEB modules in the same chassis. The figure
below shows chassis slot numbering in a 4-slot chassis. Slot 0 is the first slot
and is always the left-most slot in the rack (the first slot to the right of the
power supply).
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.
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.
