Low Voltage Directive This product is tested to meet Council Directive 73/23/EEC Low Voltage, by applying the safety requirements of EN 61131-2 Programmable Controllers, Part 2 - Equipment Requirements and Tests. For specific information required by EN 61131-2, see the appropriate sections in this publication, as well as the following Allen-Bradley publications: • Industrial Automation Wiring and Grounding Guidelines, publication 1770-4.1 • Automation Systems Catalog, publication B113 Open style devices must be provided with environmental and safety protection by proper mounting in enclosures designed for specific application conditions. See NEMA Standards publication 250 and IEC publication 529, as applicable, for explanations of the degrees of protection provided by different types of enclosure. 5 Publication 1756-IN571B-EN-P - April 2001 Enclosure and Environmental Requirements Specific To This Product This product must be mounted within a suitable system enclosure to prevent personal injury resulting from accessibility to live parts. The interior of this enclosure must be accessible only by the use of a tool. This industrial control equipment is intended to operate in a Pollution Degree 2 environment, in overvoltage category II applications, (as defined in IEC publication 664A) at altitudes up to 2000 meters without derating.

Preventing Electrostatic Discharge The 1756-CNB and 1756-CNBR modules are sensitive to electrostatic discharge. 

Understanding Standalone and Redundant Control You can use both the 1756-CNB and 1756-CNBR modules either standalone or in a redundant control chassis pair. 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 module(s) in the same corresponding slot(s) in their respective redundant control chassis pair. 

Prepare to Install the Module Before you install the module make sure you: 1. Know how to handle the module (see page 5) 2. Have all of the necessary components shown below:

3. Know the type of ControlNet network: There are two types of scheduled traffic networks for ControlNet: single-keeper networks and multi-keeper networks.

You must match the keeper to the type of network, or upgrade the firmware of the module at MAC ID 01 to be multi-keeper capable. Refer to the ControlLogix ControlNet Interface Module User Manual, publication 1756-6.5.3, for more information.
