Fixing the safety extension unit

2.3.1
To fix the safety extension unit, use the hole marked with *1 in the external view Fig. 2-4 External dimensions.
Alternatively, use DIN rails and fix it in a place free from vibration.
If using the safety extension unit in the CR860, fabricate a metal plate to install the unit, and fix the metal plate
and unit inside the CR860 controller using the following steps: For details, refer to "8.2 Appendix 2: How to Install
the Safety Extension Unit".
1) Install the safety extension unit installation metal plate to the controller door section with M4 screws.
2-14 Installation and Connection
Make sure the power of the robot controller is turned OFF before fixing the safety
extension unit, connecting the robot controller and the safety extension unit, or installing
the connectors to the safety extension unit.
Please pay attention to the orientation of insertion of the connectors. The connectors may
be broken if they are forcibly inserted in an incorrect orientation.
When an operator with static electricity installs/connects the product, the robot controller
or the safety extension unit may be broken. Start the work after all static electricity is
discharged.
Please supply power to the safety extension unit before the robot controller. When the
controller is turned on before the unit, H311(RemoteI/O unit config error) may occur.
When this error occurs, turn off both of the unit and controller and supply power to the
unit before the controller.
