NI 9758 User Manual

Environmental Management

NI is committed to designing and manufacturing products in an environmentally responsible 
manner. NI recognizes that eliminating certain hazardous substances from our products is 
beneficial to the environment and to NI customers.

For additional environmental information, refer to the 

Minimize Our Environmental Impact 

web 

page at 

ni.com/environment

. This page contains the environmental regulations and 

directives with which NI complies, as well as other environmental information not included in 
this document.

Waste Electrical and Electronic Equipment (WEEE)

EU Customers

At the end of the product life cycle, all products 

must

 be sent to 

a WEEE recycling center. For more information about WEEE recycling centers, 
National Instruments WEEE initiatives, and compliance with WEEE Directive 
2002/96/EC on Waste and Electronic Equipment, visit

Battery Replacement and Disposal

Battery Directive

Battery Directive This device contains a long-life coin cell 

battery. If you need to replace it,

 

use the Return Material Authorization (RMA) 

process or contact an authorized National

 

Instruments service representative. For 

more information about compliance with the EU

 

Battery Directive 2006/66/EC about 

Batteries and Accumulators and Waste Batteries and

 

Accumulators, visit

Ferrite Requirement for EMC Compliance

Install a clamp-on ferrite bead onto both the power supply cable and the signal cable. Power to 
the module must be off when adding ferrites. Ferrites must be connected to the power cable and 
the signal cable as close to the module as possible. Placing the ferrite elsewhere on the cable 
noticeably impairs its effectiveness. Determine the clamp-on ferrite beads to install based on 
your application. Use the following ferrites or other similar ferrites:

Power cable: Laird 28A0592-0A2

Signal cable: TDK Cat3035 (2 total)
