Safety risks during installation and service work on manipulatorsOverviewThis section includes information on general safety risks to be considered when performinginstallation and service work on the manipulator.General risks during installation and service• The instructions in the Product manual in the chapter Installation and commissioningmust always be followed.• Emergency stop buttons must be positioned in easily accessible places so that themanipulator can be stopped quickly.• Those in charge of operations must make sure that safety instructions are available forthe installation in question.• Those who install the manipulator must have the appropriate training for theequipment in question and in any safety matters associated with it.Nation/region specific regulationsTo prevent injuries and damages during the installation of the manipulator, the regulationsapplicable in the country concerned and the instructions of ABB Robotics must be compliedwith.Non-voltage related risks• Safety zones, which must be crossed before admittance, must be set up in front of themanipulator'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'sworking space.• The axes are affected by the force of gravity when the brakes are released. In additionto the risk of being hit by moving manipulator parts, there is a risk of being crushedby the parallel arm (if there is one).• Energy stored in the manipulator for the purpose of counterbalancing certain axes maybe 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, that is, do not climb on the manipulator motorsor other parts during service work. There is a serious risk of slipping because of thehigh temperature of the motors or 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 safetyfunction are interlocked in accordance with the applicable standards for that function.• The supplier of the complete system must ensure that all circuits used in theemergency stop function are interlocked in a safe manner, in accordance with theapplicable standards for the emergency stop function.Continues on next page
