explosion in a hazardous environment, which may lead to personal injury or death,
property damage, or economic loss.

ATTENTION: Identifies information about practices or circumstances that can lead to
personal injury or death, property damage, or economic loss. Attentions help you
identify a hazard, avoid a hazard and recognize the consequences.

SHOCK HAZARD: Labels may be on or inside the equipment (for example, drive or
motor) to alert people that dangerous voltage may be present.

BURN HAZARD: Labels may be on or inside the equipment (for example, drive or
motor) to alert people that surfaces may reach dangerous temperatures.

IMPORTANT Identifies information that is critical for successful application and understanding of

the product.

Environment and Enclosure

ATTENTION: 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 meters (6562 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 enclosure must have
suitable flame-retardant properties to prevent or minimize the spread of flame,
complying with a flame spread rating of 5VA, V2, V1, V0 (or equivalent) if
non-metallic. 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.

In addition to this publication, see:

• Industrial Automation Wiring and Grounding Guidelines, for additional
installation requirements, Allen-Bradley publication 1770-IN041

• NEMA Standards publication 250 and IEC publication 60529, as applicable,
for explanations of the degrees of protection provided by different types of
enclosure.

Preventing Electrostatic Discharge

ATTENTION: This 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.

• Use a static-safe workstation, if available.

• Store the equipment in appropriate static-safe packaging when not in use.

North American Hazardous Location Approval

The following information applies when
operating this equipment in hazardous
locations:

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 nam eplate indicating
the hazardous location temperature code. When comb ining
products within a system, the most adverse temp erature code
(lowest "T" number) may be used to help determ ine 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.

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 r emoved
or the area is known to be nonhazardous.
Secure any external connection s that mate
to this equipment by using screws, sliding
latches, threaded connectors, or other
means provided with this product.

• Substitution of components may impair
suitability for Class I, Division 2.

• If this product contains batt eries, they must
only be changed in an area known to be
nonhazardous.

Informations sur l’utilisation de cet
équipement en environnements dangereux:

Les produits marqués "CL I, DIV 2, GP A, B, C, D" ne
conviennent qu'à une utilisation en en vironnements de
Classe I Division 2 Groupes A, B, C, D dangereux et no n
dangereux. Chaque produit est livré avec des marquages
sur sa plaque d'identification qui indiquent le code de
température pour les environnements dangereu x. Lorsque
plusieurs produits sont combinés dans un système, le code
de température le plus défavorab le (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.

RISQUE D’EXPLOSION

• Couper le courant ou s'as surer que
l'environnement est classé non dangere ux
avant de débrancher l'équipement.

• Couper le courant ou s'as surer que
l'environnement est classé non dangere ux
avant de débrancher les connecteurs. Fixer
tous les connecteurs externes rel iés à cet
équipement à l'aide de vis, loquets
coulissants, connecteurs filetés ou autres
moyens fournis avec ce produit.

• La substitution de composants peut rendre
cet équipement inadapté à une utilisation
en environnement de Classe I, Division 2.

• S'assurer que l'environnement est classé
non dangereux avant de changer les pile s.
