Non-voltage related risks
•
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.
•
Safety zones, which must 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.
•
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.
•
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, there is a risk of
being crushed by the parallel arm (if there is one).
•
Energy stored in the robot for the purpose of counterbalancing certain axes
may be released if the robot, 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 robot as a ladder, which means, do not climb on the 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
robot. There is also a risk of the robot being damaged.
To be observed by the supplier of the complete system
When integrating the robot with external devices and machines:
•
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.

Description
Safety risk
CAUTION
Motors and gearboxes are HOT after running
the robot! Touching motors and gearboxes
may result in burns!
With a higher environment temperature, more
surfaces on the manipulator will get HOT and
may also result in burns.
Hot components!
