On robots with RobotWare earlier than 7.10, the brakes are released using an
external brake release tool, see

If there is no FlexPendant connected, or in a system failure state, the brake
release function is not immediately available. Dangerous clamping situations
should always be mitigated using safety functions, see the section

lapsing under gravity and that no personnel is at
risk of getting hit by the arm moving downwards.
