1.3.1 Safety risks during installation and service work on robots
Requirements on personnel
Only persons who know the robot and are trained in the operation and handling
of the robot are allowed to maintain the robot. Persons who are under the influence
of alcohol, drugs or any other intoxicating substances are not allowed to install,
maintain, repair, or use the robot.
• Those in charge of operations must make sure that safety instructions are
available for the installation in question.
• Those who install or service/maintain the robot must have the appropriate
training for the equipment in question and in any safety matters associated
with it.
• Personnel should be trained on responding to emergency or abnormal
situations.
General risks during installation and service
The instructions in the product manual must always be followed.
Never turn the power on to the robot before it is properly fixed and bolted to its
foundation/support.
Make sure that no one else can turn on the power to the controller and robot while
you are working with the system. A good method is to always lock the main switch
on the controller cabinet with a safety lock.
Make sure that no one else can turn on the power to the controller and robot while
you are working with the system. A good method is to remove the power cable to
the controller.
If the robot is installed at a height, hanging, or other than standing directly on the
floor, there may be additional risks than those for a robot standing directly on the
floor.
Energy stored in the robot for the purpose of counterbalancing certain axes may
be released if the robot, or parts thereof, are dismantled.
Never use the robot as a ladder, which means, do not climb on the controller,
motors, or other parts during service work. There is a risk of slipping because of
the high temperature of the motors and oil spills that can occur on the robot. There
is also a risk of the robot being damaged.
To avoid damaging the product, make sure that there are no loose screws, turnings,
or other parts inside the product after work has been performed.
Safety risks during operational disturbances
Corrective maintenance must only be carried out by qualified personnel who are
familiar with the entire installation as well as the special risks associated with its
different parts.
