Environment and Enclosure

ATTENTION

ATTENTION

This equipment is intended for use in a Pollution Degree 2 industrial
environment, in overvoltage Category II applications (as defined in IEC 60664-1),
at altitudes up to 2000 m (6562 ft) without derating.This equipment is
considered Group 1, Class A industrial equipment according to IEC/CISPR 11.
Without appropriate precautions, there may be difficulties with electromagnetic
compatibility in residential and other environments due to conducted and
radiated disturbances.

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 1770-4.1

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

Preventing Electrostatic Discharge

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.

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 removed or the area is known
to be nonhazardous. Secure any
external connections 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 batteries ,
they must only be changed in an
area known to be nonhazardous.

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

• The interior of the enclosure must
be accessible only by the use of a
tool.

• For applicable equipment (relay
modules, etc.), exposure to some
chemicals may degrade the sealing
properties of materials used in the
following devices: Relays, Epoxy. It
is recommended that the User
periodically inspect these devices
for any degradation of properties
and replace the module if
degradation is found.

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 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.

RISQUE D’EXPLOSION

• Couper le courant ou s’assurer que
l’environnement est cl assé non
dangereux avant de débrancher
l'équipement.

• Couper le courant ou s'assurer que
l'environnement est classé non
dangereux avant de débrancher les
connecteurs. Fixer tous les connecteurs
externes reliés à cet équipement à
l'aide de vis, loquets coulissants,
connecteurs filetés ou autres moye ns
fournis avec ce produit.

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

• S’assurer que l’environnement est
classé non dangereux avant de changer
les piles.

Do not remove the protective debris strip until after the module and all other
equipment in the panel near the module are mounted and wiring is complete.
Once wiring is complete, remove protective debris strip. Failure to remove strip
before operating can cause overheating.

Electrostatic discharge can damage semiconductor devices inside the module.
Do not touch the connector pins or other sensitive areas.

Pollution Degree 2 is an environment where, normally, only non-conductive pollution occurs except that occasionally a
temporary conductivity caused by condensation shall be expected.

Over Voltage Category II is the load level section of the electrical distribution system. At this level transient voltages are
controlled and do not exceed the impulse voltage capability of the product’s insulation.

Pollution Degree 2 and Over Voltage Category II are International Electrotechnical Commission (IEC) designations.

General Considerations

Most applications require installation in an industrial enclosure to reduce the effects of electrical
interference and environmental exposure. Locate your controller as far as possible from power
lines, load lines, and other sources of electrical noise such as hard-contact switches, relays, and
AC motor drives. For more information on proper grounding guidelines, see the Industrial
Automation Wiring and Grounding Guidelines, publication 1770-4.1

This product is intended to be mounted to a well-grounded mounting surface
such as a metal panel. Additional grounding connections from the power
supply's mounting tabs or DIN rail (if used) are not required unless the mounting
surface cannot be grounded. Refer to Industrial Automation Wiring and
Grounding Guidelines, Allen-Bradley publication 1770-4.1
