NI 9401 Operating Instructions and Specifications
Special Conditions for Marine Applications
Some modules are Lloyd’s Register (LR) Type Approved for
marine applications. To verify Lloyd’s Register certification, visit
ni.com/certification
and search for the LR certificate, or
look for the Lloyd’s Register mark on the module.
Caution
To meet radio frequency emission
requirements for marine applications, use shielded cables
and install the system in a metal enclosure. Suppression
ferrites must be installed on power supply inputs near
power entries to modules and controllers. Power supply
and module cables must be separated on opposite sides of
the enclosure and must enter and exit through opposing
enclosure walls.
