User Manual

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.
WARNING Identifies information about practices or circumstances that can cause
an explosion in a hazardous environment, which may lead to personal
injury or death, property damage, or economic loss.
IMPORTANT Identifies information that is critical for successful application and
understanding of the product.
ATTENTION Identifies information about practices or circumstances that can lead
to personal injury or death, property damage, or economic loss.
Attentions help you identify a hazard, avoid a hazard, and recognize
the consequence
SHOCK HAZARD Labels may be on or inside the equipment, for example, a drive or
motor, to alert people that dangerous voltage may be present.
BURN HAZARD Labels may be on or inside the equipment, for example, a drive or
motor, to alert people that surfaces may reach dangerous
temperatures.

Chapter 1
Quick Start for Experienced Users
This chapter can help you to get started using the SLC 500 Modular
Processors. We base the procedures here on the assumption that you
have an understanding of SLC 500 products. You should understand
electronic process control and be able to interpret the ladder logic
instructions required to generate the electronic signals that control
your application.
Because it is a start-up guide for experienced users, this chapter does
not contain detailed explanations about the procedures listed. It does,
however, reference other chapters in this book where you can get
more information.
If you have any questions or are unfamiliar with the terms used or
concepts presented in the procedural steps, always read the
referenced chapters and other recommended documentation before
trying to apply the information.
This chapter:
•tells you what tools and equipment you need.
•lists how to install your chassis.
•lists how to install and wire your power supply.
•lists how to install and apply power to your processor.
•lists how to establish communication with the processor.
•describes how to return the SLC 5/03, SLC 5/04, and SLC 5/05
processors to initial factory conditions if required.
