*(Reserve) Do not connect the pins.
NOTE
1 The figure shows a sample relay connector
interface. Design the cable to suit the interface of
the actual device to be connected.
2 The +24V pins of the interface for the PANEL i
shown above can be used only with the FANUC I/O
unit (such as FANUC CASSETTE and FANUC
Handy File). Do not use these pins for other
purposes. Also, do not attempt to simultaneously
connect two or more FANUC I/O units to one the
PANEL i.
If two or more I/O units are connected
simultaneously, the power supply capacity of the
+24 V pins may be exceeded.
