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://www.ab.com/manuals/gi) 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

GuardPLC 8-Digital Inputs and 8-Digital Outputs Module 5
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.
Preventing Electrostatic Discharge
ATTENTION
This equipment is sensitive to electrostatic discharge, which can
cause internal damage and affect normal operation. 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 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.

Mount the Module
IMPORTANT
The module cannot be panel-mounted. Mount the module to a DIN rail by
following the four steps below.
1. Hook the top slot over the DIN rail.
2. Insert a flathead screwdriver into the
gap between the housing and the latch
and pull the latch downward.
3. Hold the latch down as you push the
housing back onto the DIN rail.
4. Release the latch to lock the device
onto the rail.
TIP
For effective cooling:
• Mount the module horizontally.
• Provide a gap of at least 100 mm (3.94 in.) above and below
the module.
• Select a location where air flows freely or use an additional
fan.
• Do not mount the module over a heating device.

Latch
To remove the module from the DIN rail, insert a flathead
screwdriver into the gap between the housing and the latch
and pull the latch downward as you lift the module off of the
rail.
(1) Top Slot
DIN Rail
IP Address Label
A transparent label shipped with the module can be used to note the IP Address
and System ID (SRS).
IMPORTANT
Publication 1753-IN010A-EN-P - October 2005
If you attach the label to the module, make sure you do not cover
any of the ventilation slots.
