8 Actions during installation and service
To avoid injuries and damage during the installation of the robot system, the regulations
applicable in the country concerned and the instructions of ABB Robotics must be
followed. Special attention must be paid to the following points:
• The instructions in the Installation Manual must always be observed.
• The main power supply to the robot system must be arranged in such a way that it
can be turned off outside the robot's working space.
• The supplier of the entire system has to ensure that all circuits involved in the
emergency stop function are interlocked in a safe way and in accordance with
applicable standards for emergency stop function.
• Emergency stop buttons must be positioned in easily accessible places so that the
robot can be stopped quickly.
• Safety zones, to be crossed before admittance, must be arranged in front of the
robot's working space. Light beams or sensitive mats could be suitable devices for
such arrangements.
• By means of suitable arrangements such as use of turntables or the like, the operator
should be kept away from the robot's working space.
• Persons responsible for operations must make sure that safety instructions are
available at the installation in question.
• Persons involved in the installation must be trained in the robot system in question
and in safety matters associated with it.
Fault tracing must sometimes be carried out with the power supply turned on. When
repairing faults, disconnecting electric leads, and withdrawing or inserting units, the
control system must be turned off by setting the main power switch to the OFF position.
Even if the power supply for the robot is turned off, the danger of injury still
remains:
• Axes are affected by the force of gravity when releasing brakes.
This means there could be a crushing hazard around the tie rod.
• Energy which is stored in the robot for the purpose of counterbalancing
certain axes may be released in connection with dismantling.
• On dismantling / assembling mechanical units there is a danger of falling
objects.
