equipment. Safety Guidelines for the Application, Insta llat ion and Main te nanc e of So lid Stat e Contr ols
(Publication SGI-1.1 available from your local Rockwell Automation sales office or online at
http://www.literature.rockwellautomation.com) describes some important differences between solid
state equipment and hard-wired electromechanical devices. Because of this difference, and also
because of the wide variety of uses for solid state equipment, all persons responsible for applying this
equipment must satisfy themselves that each intended application of this equipment is acceptable.
In no event will Rockwell Automation, Inc. be responsible or liab le for indir ect or consequen tial damage s
resulting from the use or application of this equipment.
The examples and diagrams in this manual are included solely for illustrative purposes. Because of the
many variables and requirements associated with any particular installation, Rockwell Automation, Inc.
cannot assume responsibility or liability for actual use based on the examples and diagrams.
No patent liability is assumed by Rockwell Automation, Inc. with respect to use of information, circuits,
equipment, or software described in this manual.
Reproduction of the contents of th is manual, in whole or in part, without writ t en p e r mission of Rockwell

Environment and Enclosure

ATTENTIO

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 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.

Besides this publication, see:

• Industrial Automation Wiring and Grounding
Guidelines, Allen-Bradley publication 1770-4.1, for
additional installation requirements.

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

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 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 -

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
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.

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.

Install the Mounting Base

To install the mounting base on the DIN rail, proceed as follows.

ATTENTIO

POINT I/O is grounded through the DIN rail to chassis
ground. Use zinc-plated yellow-chromate steel DIN rail to
assure proper grounding. The use of other DIN rail
material (for example, aluminum and plastic) that can
corrode, oxidize, or are poor conductors, can result in
improper or intermittent grounding.
Secure DIN rail to mounting surface approximately every
200 mm (7.8 in.).

1. Position the mounting base vertically above the installed units
(adapter, power supply, or existing module).

2. Slide the mounting base down, allowing the interlocking side
pieces to engage the adjacent module or adapter.

Slide the mounting base to
allow the interlocking side
pieces to engage the
adjacent module or
adapter.

3. Press firmly to seat the mounting base on the DIN rail.

The mounting base snaps into place.

Install the Module

ATTENTIO

When you insert or remove the module while backplane
power is on, an electrical arc can occur. This could cause
an explosion in hazardous location installations.
Be sure that power is removed or the area is
nonhazardous before proceeding. Repeated electrical
arcing causes excessive wear to contacts on both the
module and its mating connector. Worn contacts may
create electrical resistance that can affect module
operation.

Install the module before or after base installation. Be sure that you
complete the following.

• Correctly key the mounting base before installing the module
into the mounting base.

• Position the mounting base locking screw horizontal
referenced to the base.

POINT I/O Protected Sink Output Module 9

To install the module on the DIN rail, proceed as follows.

1. Use a bladed screwdriver to rotate the keyswitch on the
mounting base clockwise until the number required for the
type of module being installed aligns with the notch in the
base.

Turn the keyswitch to align the number with the notch.
