How to Extend the Control Unit Cable (option)

To extend the length of the cable between the control unit and the processor unit, use
the appropriate cable assembly for the control unit, as listed below.

• RCU-026: 6TPSH-XH12X2-LxxSP2 (5/10/20/30 m)

used, you can operate the control unit properly, but the USB port on the control unit is
deactivated.
