Publication 1794-IN002G-EN-P - January 2004Installation InstructionsFlexLogix Controller SystemCatalog numbers 1794-L33, 1794-L34, 1794-FLAUse this document as a guide for installing your FlexLogix™ controller system. This document provides installation instructions for both the FlexLogix controller (1794-L33, -L34) and the FlexLogix extended-local I/O adapter (1794-FLA). You should already be familiar with the FlexLogix system components. See the documentation references for additional information.You must FLASH upgrade the firmware on your FlexLogix controller before you can use it. The controller ships with firmware revision 1.x but must be upgraded to match the version of RSLogix 5000 that you are using (e.g. if you are using RSLogix5000 V11, you must upgrade your FlexLogix controller firmware to revision 11.x before using it). For more information on upgrading your controller’s firmware, see page22.Tools That You NeedYou need the following tools to install your FlexLogix controller system.•slotted screwdriver•phillips screwdriver•mounting hardware (for mounting a DIN rail)•drill (for mounting a DIN rail)•needle-nose pliersObtain a User ManualThis product also has a user manual (pub. no. 1794-UM001).

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.ATTENTIONThis 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.•When not in use, store the equipment in appropriate static-safe packaging.4 FlexLogix Controller SystemPublication 1794-IN002G-EN-P - January 2004European Hazardous Location ApprovalEuropean 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.Compliance with the Essential Health and Safety Requirements has been assured by compliance with EN 50021.IMPORTANTWhen using this product, also 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.FlexLogix Controller System 5Publication 1794-IN002G-EN-P - January 2004North American Hazardous Location ApprovalThe following information applies when operating this equipment in hazardous locations:Informations sur l’utilisation de cet équipement en environnements dangereux :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.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.
