• The instructions in the Product Manual - Installation and Commissioning must always
be followed.
• Emergency stop buttons must be positioned in easily accessible places so that the
robot 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 robot must have the appropriate training for the robot system in
question and in any safety matters associated with it.
• Safety zones, which have to be crossed before admittance, must be set up in front of
the robot'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 robot'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 robot parts, you run the risk of being crushed by the
tie rod.
• Energy, stored in the robot for the purpose of counterbalancing certain axes, may be
released if the robot, or parts thereof, is dismantled.
• When dismantling/assembling mechanical units, watch out for falling objects.
• Be aware of stored heat energy in the controller.
• Never use the robot as a ladder, i.e. do not climb on the robot motors or other parts
during service work. There is a serious risk of slipping because of the high tempera-
ture of the motors or oil spills that can occur on the robot.
• 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 emer-
gency stop function are interlocked in a safe manner, in accordance with the applica-
ble standards for the emergency stop function.
• Although troubleshooting may, on occasion, have to be carried out while the power
supply is turned on, the robot must be turned off (by setting the mains switch to OFF)
when repairing faults, disconnecting electric leads and disconnecting or connecting
units.
• The mains supply to the robot must be connected in such a way that it can be turned
off outside the robot's working space.
• Be aware of stored electrical energy (DC link) in the controller.
