Without appropriate precautions, there may bedifficulties with electromagnetic compatibility in residential and otherenvironments due to conducted as well as radiated disturbances.This equipment is supplied as open-type equipment. It must be mounted withinan enclosure that is suitably designed for those specific environmentalconditions that will be present and appropriately designed to prevent personalinjury resulting from accessibility to live parts. The enclosure must have suitableflame-retardant properties to prevent or minimize the spread of flame, complyingwith a flame spread rating of 5VA, V2, V1, V0 (or equivalent) if non-metallic. Theinterior of the enclosure must be accessible only by the use of a tool. Subsequentsections of this publication may contain additional information regarding specificenclosure type ratings that are required to comply with certain product safetycertifications.In addition to this publication, see:•Industrial Automation Wiring and Grounding Guidelines, RockwellAutomation publication1770-4.1,for additional installationrequirements.•NEMA Standards 250 and IEC 60529, as applicable, for explanations ofthe degrees of protection provided by different types of enclosure.Publication1768-IN004D-EN-P - December 20094CompactLogix ControllersEuropean Hazardous Location ApprovalConsider the following if you install a 1768-L43S or 1768-L45Scontroller in a European Zone 2 location.European Zone 2 Certification (The following applies when the product bears theEX marking.)This equipment is intended for use in potentially explosive atmospheres as defined byEuropean Union Directive 94/9/EC and has been found to comply with the Essential Healthand Safety Requirements relating to the design and construction of Category 3 equipmentintended for use in Zone 2 potentially explosive atmospheres, given in Annex II to thisDirective.Compliance with the Essential Health and Safety Requirements has been assured bycompliance with EN 60079-15 and EN 60079-0.WARNING•This equipment must be installed in an enclosure providing at least IP54protection when applied in Zone 2 environments.•This equipment shall be used within its specified ratings defined byAllen-Bradley.•Provision shall be made to prevent the rated voltage from beingexceeded by transient disturbances of more than 40% when applied inZone 2 environments.•This equipment is not resistant to sunlight or other sources of UVradiation.•Secure any external connections that mate to this equipment by usingscrews, sliding latches, threaded connectors, or other means providedwith this product.•Do not disconnect equipment unless power has been removed or thearea is known to be nonhazardous.General Safety Information for 1768-L43S and 1768-L45S ControllersATTENTIONPersonnel responsible for the application of safety-related programmableelectronic systems (PES) shall be aware of the safety requirements in theapplication of the system and shall be trained in using the system.Publication1768-IN004D-EN-P - December 2009CompactLogix Controllers5North American Hazardous Location ApprovalThe following information applies whenoperating this equipment in hazardouslocations.Products marked "CL I, DIV 2, GP A, B, C, D" are suitable foruse in Class I Division 2 Groups A, B, C, D, HazardousLocations and nonhazardous locations only. Each product issupplied with markings on the rating nameplate indicatingthe hazardous location temperature code. Whencombining products within a system, the most adversetemperature code (lowest "T" number) may be used to helpdetermine the overall temperature code of the system.Combinations of equipment in your system are subject toinvestigation by the local Authority Having Jurisdiction atthe time of installation.Informations sur l’utilisation de cetéquipement en environnements dangereux.Les produits marqués "CL I, DIV 2, GP A, B, C, D" neconviennent qu'à une utilisation en environnements deClasse I Division 2 Groupes A, B, C, D dangereux et nondangereux. Chaque produit est livré avec des marquages sursa plaque d'identification qui indiquent le code detempérature pour les environnements dangereux. Lorsqueplusieurs produits sont combinés dans un système, le code detempérature le plus défavorable (code de température le plusfaible) peut être utilisé pour déterminer le code detempérature global du système. Les combinaisonsd'équipements dans le système sont sujettes à inspection parles autorités locales qualifiées au moment de l'installation.AVERTISSEMENTWARNINGEXPLOSION HAZARD -• Do not disconnect equipment unlesspower has been removed or thearea is known to be nonhazardous.• Do not disconnect connections tothis equipment unless power hasbeen removed or the area is knownto be nonhazardous.
