Clamp the cable shield with the cable clamp on the grounding plate
of the cabinet on the built–in I/O card side.
When the cable used is not a shield cable, it must be used only within
the cabinet.
(8) Provide sufficient space under the unit to allow the cable to be
connected to and detached from the built–in I/O card.
(9) Ensure that the cable is securely plugged into the unit. Otherwise,
problems such as DI/DO signal transfer errors may occur.
