1.7 Safe troubleshooting
1.7.1 Robot without axes' holding brakes are potentially lethal
Description
Since the robot arm system is quite heavy, especially on larger robot models, it is
dangerous if the holding brakes are disconnected, faulty, worn or in any way
rendered non-operational.
For example, a collapsing manipulator may kill or seriously injure a person standing
beneath it.

system by some other means before
working on it.
