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.
