Prevent Electrostatic Discharge

Electrostatic discharge can damage integrated circuits or semiconductors if
you touch bus connector pins. Follow these guidelines when you handle the
module.

• Touch a grounded object to discharge static potential.

• Wear an approved wrist-strap grounding device.

• Do not touch the bus connector or connector pins.

• Do not touch circuit components inside the module.

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

• Keep the module in its static-shield box when not in use.

Remove Power

Remove power before removing or installing this module. When you remove
or install a module with power applied, an electrical arc may occur. An
electrical arc can cause personal injury or property damage by:

• sending an erroneous signal to your system’s field devices, causing
unintended machine motion.

• causing an explosion in a hazardous environment.

• causing permanent damage to the module’s circuitry.

Electrical arcing causes excessive wear to contacts on both the module and its
mating connector. Worn contacts may create electrical resistance.

WARNING

AVERTISSEMENT

North American Hazardous Location Approval

The following modules are North American Hazardous Location approved: 1762-IQ8OW6

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 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.

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 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 I, Division 2.

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

TIP

ATTENTION

Install the DC-Input/Relay-Output Combination Module

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

Maintain spacing from enclosure walls, wireways, and adjacent equipment. Allow 50.8 mm
(2 in.) of space on all sides for adequate ventilation, as shown:

Mount the Module on a DIN Rail

The module can be mounted using the following DIN rails: 35 x 7.5 mm
(EN 50 022 - 35 x 7.5) or 35 x 15 mm (EN 50 022 - 35 x 15).

Before mounting the module on a DIN-rail, close the DIN-rail latch. Press the DIN-rail
mounting area of the module against the DIN-rail. The latch will momentarily open and lock
into place.

Use DIN-rail end anchors (Allen-Bradley part number 1492-EA35 or 1492-EAH35) for
vibration or shock environments.

Publication 1762-IN018B-EN-P - July 2013

1762 expansion I/O is only mounted horizontally.

During panel or DIN-rail mounting of all devices, be sure that all debris
(metal chips or wire strands) is kept from falling into the module. Debris
that falls into the module could cause damage when power is applied to the
module.
