1.2.2.1. Safety risks during installation and service work on manipulators
Overview
This section includes information on general safety risks to be considered when performing
installation and service work on the manipulator.
General risks during installation and service
• The instructions in the product manual in the chapter Installation and commissioning
must always be followed.
• Emergency stop buttons must be positioned in easily accessible places so that the
manipulator can be stopped quickly.
• Those in charge of operations must make sure that safety instructions are available for
the installation in question.
• Those who install the manipulator must have the appropriate training for the
equipment in question and in any safety matters associated with it.
Nation/region specific regulations
To prevent injuries and damages during the installation of the manipulator, the regulations
applicable in the country concerned and the instructions of ABB Robotics must be complied
with.
Non-voltage related risks
• Safety zones, which must be crossed before admittance, must be set up in front of the
manipulator's working space. Light beams or sensitive mats are suitable devices.
• Turntables or the like should be used to keep the operator out of the manipulator's
working space.
• The axes are affected by the force of gravity when the brakes are released. In addition
to the risk of being hit by moving manipulator parts, there is a risk of being crushed
by the parallel arm (if there is one).
• Energy stored in the manipulator for the purpose of counterbalancing certain axes may
be released if the manipulator, or parts thereof, are dismantled.
• When dismantling/assembling mechanical units, watch out for falling objects.
• Be aware of stored heat energy in the controller.
• Never use the manipulator as a ladder, which means, do not climb on the manipulator
motors or other parts during service work. There is a serious risk of slipping because
of the high temperature of the motors and oil spills that can occur on the manipulator.
To be observed by the supplier of the complete system
• The supplier of the complete system must ensure that all circuits used in the safety
function are interlocked in accordance with the applicable standards for that function.
• The supplier of the complete system must ensure that all circuits used in the
emergency stop function are interlocked in a safe manner, in accordance with the
applicable standards for the emergency stop function.
