Environment and Enclosure
ATTENTION This equipment is intended for use in a Pollution Degree 2 industrial
environment,inovervoltageCategoryIIapplications(asdefinedinIEC
publication60664-1),ataltitudesupto2000meterswithoutderating.
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 Industrial Automation Wiring
and Grounding Guidelines, Allen-Bradley publication 1770-4.1, for
additional installation requirements pertaining to this equipment.

Grounding Guidelines, publication 1770-4.1.
About the 1756-CNB and 1756-CNBR Series E Modules
The 1756-CNB and 1756-CNBR Series E modules work for all nonredundant
ControlLogix applications.
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 workstation.
•Whennot inuse, storethe equipmentinappropriatestatic-safe
packaging.
IMPORTANT Only the 1756-CNB and 1756-CNBR, Series D modules are
supported in ControlLogix Redundancy releases 8, 11, 13, and 15.
After a firmware upgrade to version 11.xx, Series E will be
supported in ControlLogix Redundancy release 15 or later.
You cannot upgrade a Series D module to a Series E module.
ControlLogix ControlNet Interface Module 7
Publication 1756-IN604A-EN-P - February 2006
Understand Standalone and Redundant Control
You can use the 1756-CNB and 1756-CNBR Series E modules as standalone
or in firmware version 11.xx as redundant control. For standalone control,
only one set of modules is required. For redundant control, two ControlLogix
chassis are populated with identical pairs of modules called partners. The
chassis that performs active control is called the primary chassis and the
modules in the chassis are called primary modules. The other chassis is called
the secondary chassis and the modules in the chassis are called secondary
modules. These installation instructions discuss both standalone and
redundant control; read them carefully to distinguish the procedures and
requirements for each type of control.
IMPORTANT If you use redundant control, you must select the same ControlNet
network address for each set of partner modules. You must also
place the partner modules in the same corresponding slots in their
respective redundant control chassis pair.

Before You Begin
Before you install the module you need to make sure you:
•Know how to handle the module.
Refer to the section Prevent Electrostatic Discharge.
•Have all of the necessary components:
•Know the type of ControlNet network:
There are two types of scheduled traffic networks for ControlNet:
single-keeper networks and multi-keeper networks.
