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.
