Important User Information
Solid state equipment has operational characteristics differing from those of
electromechanical equipment. Safety Guidelines for the Application, Installation and
Maintenance of Solid State Controls (Publication SGI-1.1 available from your local Rockwell
Automation sales office or online at http://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 liable for indirect or
consequential damages 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 this manual, in whole or in part, without written permission
of Rockwell Automation, Inc., is prohibited.
Throughout this manual, when necessary, we use notes to make you aware of safety
considerations.

ATTENTION
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.
• If available, use a static-safe workstation.
• When not in use, store the equipment in
appropriate static-safe packaging.

ATTENTION
Environment and Enclosure
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.
See NEMA Standards publication 250 and IEC
publication 60529, as applicable, for explanations of
the degrees of protection provided by different
types of enclosure. Also, see the appropriate
sections in this publication, as well as the
Allen-Bradley publication 1770-4.1 (“Industrial
Automation Wiring and Grounding Guidelines”), for
additional installation requirements pertaining to
this equipment.

POINT I/O DeviceNet Communication Interface Module 5
ATTENTION
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 (e.g., aluminum, plastic,
etc.) 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.

Install the Module
To install the module on the DIN rail, proceed as follows.
ATTENTION
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.
W orn contacts may create electrical resistance that
can affect module operation.
1. Position the module vertically above the DIN rail
2. Press down firmly to install the module on the DIN rail.
The locking mechanism will lock the module to the DIN rail.
3. Remove the safety end cap by sliding it up to expose the
backplane and power interconnections.
ATTENTION
Do not discard the end cap. Use this end cap to
cover the exposed interconnections on the last
mounting base on the DIN rail. Failure to do so
could result in equipment damage or injury from
electric shock.

Install the Module in an Existing System
To install a replacement module in an existing system, proceed as
follows.
1. To remove the module from the DIN rail, pull up on the RTB
removal handle to remove the terminal block.
WARNING
When you connect or disconnect the Removable
Terminal Block (RTB) with field-side power
applied, 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.
2. Use a small-bladed screwdriver to rotate the DIN rail locking
screw to a vertical position.
This releases the locking mechanism.
3. Lift straight up to remove.
4. Position the module vertically above the DIN rail.
5. Slide the module down so that the interlocking side pieces
engage the adjacent module.
6. Press firmly to seat the module on the DIN rail.
The module locking mechanism will snap into place.
