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 sui table 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 nameplate ind icating
the hazardous location temperatu re code. When
combining products within a system, the most adverse
temperature code (lowest “T” number) may be used to
help determine the overall temperature cod e of the
system. Combinations of equipment in your syst em are
subject to investigation by the local Authority Having
Jurisdiction at the time of installa tion.
EXPLOSION HAZARD -
WARNING
• 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.
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 D ivision 2
Groupes A, B, C, D dangereux et non danger eux. Chaque
produit est livré avec des marquages sur sa plaque
d’identification qui indiquent le co de de température pour les
environnements dangereux. Lorsque plusieurs prod uits 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 temp érature global du
système. Les combinaisons d’équipements dans le système
sont sujettes à inspection par les autorités locales qualifiées
au moment de l’installation.
AVERTISSEMENT
RISQUE D’EXPLOSION –
• Couper le courant ou s’assurer que
l’environnement est classé 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 moyens fournis avec ce
produit.
• La substitution de composants peut
rendre cet équipement inadapté à une
utilisation en environnement de
Classe 1, Division 2.
• S’assurer que l’environnement est
classé non dangereux avant de
changer les piles.
ATTENTION
This product is grounded through the DIN rail to chassis ground. Use
zinc plated, yellow-chromate steel DIN rail to be sure of proper
grounding. The use of other DIN rail materials, such as aluminum and
plastic, which can corrode, oxidize, or are poor conductors, can result
in improper or intermittent grounding. Secure DIN rail to mounting
surface approximately every 200 mm (7.87 in.) and use end-anchors
appropriately.

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 feet)
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.
Besides this publication, see:
• Industrial Automation Wiring and Grounding Guidelines, for
additional installation requirements, Allen-Bradley publication
1770-4.1.
Publication
• NEMA Standards publication 250 and IEC publication 60529, as
applicable, for explanations of the degrees of protection provided
by different types of enclosure.

Prevent Electrostatic Discharge
POINT I/O 220V ac Input Module 5
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.
