Special Conditions for Marine Applications

Some products are Lloyd’s Register (LR) Type Approved for

marine (shipboard) applications. To verify Lloyd’s Register

certification for a product, visit 

ni.com/certification

 and search

for the LR certificate, or look for the Lloyd’s Register mark on

the product.

Caution

 

In order to meet the EMC requirements for

marine applications, install the product in a shielded

enclosure with shielded and/or filtered power and

input/output ports. In addition, take precautions when

designing, selecting, and installing measurement probes

and cables to ensure that the desired EMC performance

is attained.
