Product documentation
Categories for user documentation from ABB Robotics
The user documentation from ABB Robotics is divided into a number of categories.
This listing is based on the type of information in the documents, regardless of
whether the products are standard or optional.
Tip
All documents can be found via myABB Business Portal, www.abb.com/myABB.
Product manuals
Manipulators, controllers, DressPack/SpotPack, and most other hardware is
delivered with a Product manual that generally contains:
• Safety information.
• Installation and commissioning (descriptions of mechanical installation or
electrical connections).
•Maintenance (descriptions of all required preventive maintenance procedures
including intervals and expected life time of parts).
• Repair (descriptions of all recommended repair procedures including spare
parts).
• Calibration.
• Decommissioning.
•Reference information (safety standards, unit conversions, screw joints, lists
of tools).
• Spare parts list with corresponding figures (or references to separate spare
parts lists).
• References to circuit diagrams.
Technical reference manuals
The technical reference manuals describe reference information for robotics
products, for example lubrication, the RAPID language, and system parameters.
Application manuals
Specific applications (for example software or hardware options) are described in
Application manuals. An application manual can describe one or several
applications.
An application manual generally contains information about:
• The purpose of the application (what it does and when it is useful).
•What is included (for example cables, I/O boards, RAPID instructions, system
parameters, software).
• How to install included or required hardware.
• How to use the application.
• Examples of how to use the application.

How to read the product manual
Reading the procedures
The procedures contain all information required for the installation or service activity
and can be printed out separately when needed for a certain service procedure.
Safety information
The manual includes a separate safety chapter that must be read through before
proceeding with any service or installation procedures. All procedures also include
specific safety information when dangerous steps are to be performed.
Read more in the chapter Safety on page 15.
Illustrations
The product is illustrated with general figures that does not take painting or
protection type in consideration.
Likewise, certain work methods or general information that is valid for several
product models, can be illustrated with illustrations that show a different product
model than the one that is described in the current manual.

1.1 Safety information
1.1.1 Limitation of liability
Limitation of liability
Any information given in this manual regarding safety must not be construed as a
warranty by ABB that the industrial robot will not cause injury or damage even if
all safety instructions are complied with.
The information does not cover how to design, install and operate a robot system,
nor does it cover all peripheral equipment that can influence the safety of the robot
system.
In particular, liability cannot be accepted if injury or damage has been caused for
any of the following reasons:
• Use of the robot in other ways than intended.
• Incorrect operation or maintenance.
• Operation of the robot when the safety devices are defective, not in their
intended location or in any other way not working.
• When instructions for operation and maintenance are not followed.
• Non-authorized design modifications of the robot.
• Repairs on the robot and its spare parts carried out by in-experienced or
non-qualified personnel.
• Foreign objects.
• Force majeure.
Spare parts and equipment
ABB supplies original spare parts and equipment which have been tested and
approved. The installation and/or use of non-original spare parts and equipment
can negatively affect the safety, function, performance, and structural properties
of the robot. ABB is not liable for damages caused by the use of non-original spare
parts and equipment.

1.2.2 Safety symbols on manipulator labels
Introduction to symbols
This section describes safety symbols used on labels (stickers) on the manipulator.
Symbols are used in combinations on the labels, describing each specific warning.
The descriptions in this section are generic, the labels can contain additional
information such as values.
Note
The symbols on the labels on the product must be observed. Additional symbols
added by the integrator must also be observed.
Types of symbols
Both the manipulator and the controller are marked with symbols, containing
important information about the product. This is important for all personnel handling
the robot, for example during installation, service, or operation.
The safety labels are language independent, they only use graphics. See Symbols
on safety labels on page 19.
The information labels can contain information in text.
