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 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
•recognize the consequence
SHOCK HAZARD Labels may be located on or inside the equipment (e.g.,
drive or motor) to alert people that dangerous voltage may
be present.
BURN HAZARD Labels may be located on or inside the equipment (e.g.,
drive or motor) to alert people that surfaces may be
dangerous temperatures.

Safety Information
Simply Pico
Clever Switching and Controlling
Pico is a compact, user-friendly and low-cost controller for simple
control applications. Applications range from building and domestic
automation to machine and plant control. Pico has built-in
user-friendly operating elements and an LCD display.
Connect Pico and draw a circuit diagram on the display by pressing
the buttons on the device. Pico works with make contacts, break
contacts, and relays.
Enter a circuit diagram in Pico just like it is sketched on paper. Pico
has basic and advanced functions for relays, time switches and
contactors, among other functions. Make changes to the circuit by
pressing the buttons on the device. Time consuming rewiring is not
necessary.
ATTENTION Electrical Shock Hazard
The electrical installation and commissioning work
must only be carried out by suitably qualified
personnel.
Do not work on the device when the power is turned
on.
Observe the relevant safety regulations:
•Turn off the power
•Make sure that the device cannot be powered on
again inadvertently
•Check to make sure that no dangerous voltages
are present before working on the device
