or if the product is used in residential or commercial areas. To minimize interference with radio
and television reception and prevent unacceptable performance degradation, install and use this
product in strict accordance with the instructions in the product documentation.
Furthermore, any modifications to the product not expressly approved by National Instruments
could void your authority to operate it under your local regulatory rules.
Caution To ensure the specified EMC performance, product installation requires
either special considerations or user-installed, add-on devices. Refer to the
Grounding the Chassis and Wiring Power to the cRIO Controller sections for more
information.
Caution To ensure the specified EMC performance, operate this product only with
shielded cables and accessories. Exceptions are the input DC power cables, which
may be unshielded, and the RS-485 cable, which must be unshielded.
