Connection procedure
Wire cables to the CNUSR11 and CNUSR12 user wiring connectors (attachment), and fit them into the
corresponding connectors (ports) located on the rear side of the controller.
The customer needs to prepare the following items.
• Cable: AWG24 to 16 (0.2 to 1.5mm
• Flathead screwdriver: The width of the tip is 2.5mm.
1) Prepare the user wiring connector (attachment).
2) Strip off 7 mm of the cable sheath.
3) Insert the cable all the way in the insertion hole while pressing down the latch on the user wiring connector
with a flatblade screwdriver.
4) When all the required wirings have been completed, fit the user wiring connector (CNUSR11/CNUSR12)
into the corresponding connector (CNUSR11/CNUSR12 port) on the controller.
5) When the user wiring connector has properly fitted, the levers on both sides of the connector rise and the
connector is fixed. (To dismount the connector, lower the levers.)

Fully check the number of the cable insertion hole (connector pin number) for
incorrect connection. Incorrect wiring may damage the robot or cause a
malfunction.
When wiring to the CNUSR11/CNUSR12 connector, pay attention to fraying wires
of the core wires. The fraying wires can come into contact with the adjacent
terminal, causing a short circuit.
Do not apply solder on core wires. Doing so may cause a contact failure.
