CSA Hazardous Location Approval Approbation d'utilisation dans des emplacements dangereux par la

CSA certifies products for general use as well as for use in hazardous locations. Actual CSA certification is indicated by the product label as shown below, and not by statements in any user documentation.

Example of the CSA certification product label Exemple d'étiquette de certification d'un produit par la CSA

To comply with CSA certification for use in hazardous locations, the following information becomes a part of the product literature for CSAcertified AllenBradley industrial control products.

• This equipment is suitable for use in Class I, Division 2,

Groups A, B, C, D, or nonhazardous locations only.

• The products having the appropriate CSA markings (that is, Class

I Division 2, Groups A, B, C, D), are certified for use in other equipment where the suitability of combination (that is, application or use) is determined by the CSA or the local inspection office having jurisdiction.

Important: Due to the modular nature of a PLC control system, the product with the highest temperature rating determines the overall temperature code rating of a PLC control system in a Class I, Division 2 location. The temperature code rating is marked on the product labelas shown.

CSA

La CSA certifie les produits d'utilisation générale aussi bien que ceux qui s'utilisent dans des emplacements dangereux. La certification CSA en vigueur est indiquée par l'étiquette du produit et non par des affirmations dans la documentation à l'usage des utilisateurs.

Pour satisfaire à la certification de la CSA dans des endroits dangereux, les informations suivantes font partie intégrante de la documentation des produits industriels de contrôle AllenBradley certifiés par la CSA.

• Cet équipement convient à l'utilisation dans des emplacements de

Classe 1, Division 2, Groupes A, B, C, D, ou ne convient qu'à l'utilisation dans des endroits non dangereux.

• Les produits portant le marquage approprié de la CSA (c'est à dire,

Classe 1, Division 2, Groupes A, B, C, D) sont certifiés à l'utilisation pour d'autres équipements où la convenance de combinaison (application ou utilisation) est déterminée par la CSA ou le bureau local d'inspection qualifié.

Important: Par suite de la nature modulaire du système de contrôle PLC), le produit ayant le taux le plus élevé de température détermine le taux d'ensemble du code de température du système de contrôle d'un PLC dans un emplacement de Classe 1, Division 2. Le taux du code de température est indiqué sur l'étiquette du produit.

Temperature code rating

Look for temperature code rating here

The following warnings apply to products having CSA certification for use in hazardous locations.

ATTENTION: Explosion hazard 

• Substitution of components may impair suitability

for Class I, Division 2.

• Do not replace components unless power has

been switched off or the area is known to be nonhazardous.

• Do not disconnect equipment unless power has

been switched off or the area is known to be nonhazardous.

• Do not disconnect connectors unless power has

been switched off or the area is known to be nonhazardous. Secure any usersupplied connectors that mate to external circuits on an AllenBradley product using screws, sliding latches, threaded connectors, or other means such that any connection can withstand a 15 Newton (3.4 lb.) separating force applied for a minimum of one minute.

Taux du code de température

Les avertissements suivants s'appliquent aux produits ayant la certification CSA pour leur utilisation dans des emplacements dangereux.

AVERTISSEMENT: Risque d'explosion 

• La substitution de composants peut rendre ce matériel

inacceptable pour lesemplacements de Classe I, Division 2.

• Couper le courant ou s'assurer quel'emplacement est

désigné non dangereux avant de remplacer lescomposants.

• Avant de débrancher l'équipement, couper le courant

ou s'assurer que l'emplacement est désigné non dangereux.

• Avant de débrancher les connecteurs, couper le

courant ou s'assurer que l'emplacement est reconnu non dangereux. Attacher tous connecteurs fournis par l'utilisateur et reliés aux circuits externes d'un appareil AllenBradley à l 'aide de vis, loquets coulissants, connecteurs filetés ou autres moyens permettant aux connexions de résister à une force de séparation de 15 newtons (3,4 lb.  1,5 kg) appliquée pendant au moins une minute.
