Ultimately, the best safeguard is trained personnel. The user is responsible for providing personnel
who are adequately trained to operate, program, and maintain the robot cell. The robot must not be
operated by personnel who have not been trained!
We recommend that all personnel who intend to operate, program, repair, or use the robot system be
trained in an approved Motoman training course and become familiar with the proper operation of the
system. This safety section addresses the following:
• Standard Conventions (Section 2.2)
• General Safeguarding Tips (Section 2.3)
• Mechanical Safety Devices (Section 2.4)

2.3 General Safeguarding Tips
All operators, programmers, plant and tooling engineers, maintenance personnel, supervisors, and
anyone working near the robot must become familiar with the operation of this equipment. All
personnel involved with the operation of the equipment must understand potential dangers of
operation. General safeguarding tips are as follows:
• Improper operation can result in personal injury and/or damage to the equipment. Only
trained personnel familiar with the operation of this robot, the operator's manuals, the system
equipment, and options and accessories should be permitted to operate this robot system.
• Do not enter the robot cell while it is in automatic operation. Programmers must have the
teach pendant when they enter the robot cell.
• Improper connections can damage the robot. All connections must be made within the
standard voltage and current ratings of the robot I/O (Inputs and Outputs).
• The robot must be placed in Emergency Stop (E-STOP) mode whenever it is not in use.
• In accordance with ANSI/RIA R15.06-1999, section 4.2.5, Sources of Energy, use
lockout/tagout procedures during equipment maintenance. Refer also to Section 1910.147
(29CFR, Part 1910), Occupational Safety and Health Standards for General Industry
(OSHA).
2.4 Mechanical Safety Devices
The safe operation of the robot, positioner, auxiliary equipment, and system is ultimately the user's
responsibility. The conditions under which the equipment will be operated safely should be reviewed
by the user. The user must be aware of the various national codes, ANSI/RIA R15.06-1999 safety
standards, and other local codes that may pertain to the installation and use of industrial equipment.
Additional safety measures for personnel and equipment may be required depending on system
installation, operation, and/or location. The following safety equipment is provided as standard:
• Safety fences and barriers
• Light curtains and/or safety mats
• Door interlocks
• Emergency stop palm buttons located on operator station, robot controller, and
programming pendant
Check all safety equipment frequently for proper operation. Repair or replace any non-functioning
safety equipment immediately.

2.5 Installation Safety
Safe installation is essential for protection of people and equipment. The following suggestions are
intended to supplement, but not replace, existing federal, local, and state laws and regulations.
Additional safety measures for personnel and equipment may be required depending on system
installation, operation, and/or location. Installation tips are as follows:
• Be sure that only qualified personnel familiar with national codes, local codes, and
ANSI/RIA R15.06-1999 safety standards are permitted to install the equipment.
• Identify the work envelope of each robot with floor markings, signs, and barriers.
• Position all controllers outside the robot work envelope.
• Whenever possible, install safety fences to protect against unauthorized entry into the work
envelope.
• Eliminate areas where personnel might get trapped between a moving robot and other
equipment (pinch points).
• Provide sufficient room inside the workcell to permit safe teaching and maintenance
procedures.
2.6 Programming, Operation, and Maintenance Safety
All operators, programmers, plant and tooling engineers, maintenance personnel, supervisors, and
anyone working near the robot must become familiar with the operation of this equipment. Improper
operation can result in personal injury and/or damage to the equipment. Only trained personnel
familiar with the operation, manuals, electrical design, and equipment interconnections of this robot
should be permitted to program, operate, and maintain the system. All personnel involved with the
operation of the equipment must understand potential dangers of operation.
• Inspect the robot and work envelope to be sure no potentially hazardous conditions exist. Be
sure the area is clean and free of water, oil, debris, etc.
• Be sure that all safeguards are in place. Check all safety equipment for proper operation.
Repair or replace any non-functioning safety equipment immediately.
• Do not enter the robot cell while it is in automatic operation. Be sure that only the person
holding the programming pendant enters the workcell.
• Check the E-STOP button on the programming pendant for proper operation before
programming. The robot must be placed in Emergency Stop (E-STOP) mode whenever it is
not in use.
• Back up all programs and jobs onto suitable media before program changes are made. To
avoid loss of information, programs, or jobs, a backup must always be made before any
service procedures are done and before any changes are made to options, accessories, or
equipment.

• Any modifications to PART 1, System Section, of the robot controller concurrent I/O
program can cause severe personal injury or death, as well as damage to the robot! Do not
make any modifications to PART 1, System Section. Making any changes without the written
permission of Motoman will VOID YOUR WARRANTY!
• Some operations require standard passwords and some require special passwords. Special
passwords are for Motoman use only. YOUR WARRANTY WILL BE VOID if you use
these special passwords.
• The robot controller allows modifications of PART 2, User Section, of the concurrent I/O
program and modifications to controller parameters for maximum robot performance. Great
care must be taken when making these modifications. All modifications made to the
controller will change the way the robot operates and can cause severe personal injury or
death, as well as damage the robot and other parts of the system. Double-check all
modifications under every mode of robot operation to ensure that you have not created
hazards or dangerous situations.
• Check and test any new or modified program at low speed for at least one full cycle.
• This equipment has multiple sources of electrical supply. Electrical interconnections are
made between the controller and other equipment. Disconnect and lockout/tagout all
electrical circuits before making any modifications or connections.
• Do not perform any maintenance procedures before reading and understanding the proper
procedures in the appropriate manual.
• Use proper replacement parts.
• Improper connections can damage the robot. All connections must be made within the
standard voltage and current ratings of the robot I/O (Inputs and Outputs).
