When unlocking the safety configuration, the robot arm will be powered off while
changes are being made. The robot arm cannot be powered on until the changes
have been applied or reverted, and a manual power on is performed from the ini-
tialization screen.
Any changes to the safety configuration must be applied or reverted, before nav-
igating away from the Installation tab. These changes are not in effect until after
the Apply button is pressed and confirmation is performed. Confirmation requires
visual inspection of the changes given to the robot arm. For safety reasons, the
information shown is given in SI Units. An example of the confirmation dialog is
shown below.
