Wiring and Electrical Installation
INDICATIONS
Emergency stop devices need to be installed according to the generally valid
and accepted engineering standards, e.g., European standards EN 60204 and
related. The Emergency Stop Device provided by Franka Robotics needs to
be connected to the X3 port. Other devices than the Emergency Stop Device
provided by Franka Robotics may be connected to the X3 port as well.
The devices connected to the emergency stop signal must follow EN 60947-
5-5 or EN 62061. Connected emergency stop devices must be placed such
that they are easily reachable in case of emergency. Disconnected emergency
devices must be removed to prevent misunderstandings.
For more information on wiring, see "Wiring for X3" in paragraph "Safety
Settings and Watchman".
