A-B 1746-P SLC 500 Power Supplies

ATTENTION

!

Environment and Enclosure

This equipment is intended for use in a Pollution Degree 2

industrial environment, in overvoltage Category II applications

(as defined in IEC publication 60664-1), at altitudes up to

2000 m (6561 ft) without derating.

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.

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 Industrial Automation Wiring and Grounding

Guidelines, publication 1770-4.1. for additional installation

requirements pertaining to this equipment.

Overview

Install your power supply using these installation instructions. The only tools you

require are flat head (1/8”) and Phillips head (1/4”, #2) screwdrivers.

ATTENTION

!

Electrostatic discharge can damage integrated circuits or

semiconductors if you touch backplane connector pins. Follow

these guidelines when you handle the power supplies.

• Touch a grounded object to discharge static potential.

• Do not touch the backplane connector or connector pins.

• Do not touch circuit components inside the power supply.

• Use a static-safe work station, if available.

• Keep the power supplies in their static-shield packaging

when not in use.

Hazardous Location Considerations

Products marked CL1, DIV 2, GP A, B, C, D are suitable for use in Class I, Division

2, Groups A, B, C, D or 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.

WARNING

!

EXPLOSION HAZARD

• Do not disconnect equipment unless power has been

removed or the area is known to be nonhazardous.

• Do not disconnect connections to this equipment unless

power has been removed or the area is known to be

nonhazardous. Secure any external connections that mate

to this equipment using screws, sliding latches, threaded

connectors, or other means provided with this product.

• Substitution of components may impair suitability for Class

I, Division 2.

• All wiring must comply with N.E.C. article 501-4(b).

Environnements dangereux

Les produits marqués « CL 1, 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.

WARNING

!

DANGER D’EXPLOSION

• Coupez l’alimentation ou vérifiez que l’environnement est

classé non dangereux avant de débrancher l’équipement.

• Coupez l’alimentation ou vérifiez que l’environnement est

classé non dangereux avant de débrancher les connecteurs.
