accessories unless they are installed in a shielded enclosure with properly
designed and shielded input/output ports and connected to the product
using a shielded cable. If unshielded cables or accessories are not properly
installed and shielded, the EMC specifications for the product are no
longer guaranteed.
Caution
Electrostatic Discharge (ESD) can damage the NI-9232. To
prevent damage, use industry-standard ESD prevention measures during
installation, maintenance, and operation.
Caution
To ensure the specified EMC performance for the NI-9232 with
screw terminal, you must install clamp-on ferrite beads (part number
782802-01) in accordance with the product installation instructions. Refer
to the NI-9232 product page on ni.com for purchasing information about
clamp-on ferrite beads.
Notice
To ensure the specified EMC performance, the length of all I/O
cables must be no longer than 3 m (10 ft).
Cable Requirements for EMC Compliance
Select and install cables for the NI-9232 in accordance with the following
requirements:
■
Connect the cable shield to the chassis ground (grounding screw of the
chassis).
■
For the NI-9232 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-9232.
■
For the NI-9232 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.
