Refer to the NI 9230 product page on
purchasing information about clamp-on ferrite beads.
Caution
To ensure the specified EMC performance,
the length of all I/O cables must be no longer than 30 m
(100 ft).
Cable Requirements for EMC Compliance
Select and install cables for the NI 9230 in accordance with the
following requirements:
•
Connect the cable shield to the chassis ground (grounding
screw of the chassis).
•
For the NI 9230 with screw terminal, install a clamp-on
ferrite bead (part number 782802-01) on the input cable for
each channel that you are connecting to on the NI 9230.
•
For the NI 9230 with screw terminal, clamp-on ferrite beads
must be installed on the cable as close to the module as
possible. Placing the ferrite elsewhere on the cable noticeably
impairs its effectiveness.
