Chassis and Component Certifications 
Ensure that the chassis and certain components; such as the power supply, peripheral drives,  
wiring, and cables; are components certified for the country or market where used.  Agency 
certification marks on the product are proof of certification.  Typical product certifications include: 
•  In Europe 
The CE marking signifies compliance with all applicable European requirements.  If the 
chassis and other components are not properly CE marked, a supplier’s Declaration of 
Conformity statement to the European EMC directive and Low Voltage directive (as 
applicable), should be obtained.  Additionally, other directives, such as the Radio and 
Telecommunications Terminal Equipment (R&TTE) directive may also apply depending on 
product features.   
•  In the United States 
A certification mark by a Nationally Recognized Testing Laboratory (NRTL) such as UL, 
CSA, or ETL signifies compliance with safety requirements.  Wiring and cables must also be 
UL listed or recognized and suitable for the intended use.  The FCC Class B logo for home or 
office use signifies compliance with electromagnetic interference (EMI) requirements. 
•  In Canada 
A nationally recognized certification mark such as CSA or cUL signifies compliance with 
safety requirements.  The Industry Canada statement at the front of this product guide 
demonstrates compliance with Canadian EMC regulations.  Industry Canada recognizes and 
accepts FCC certification as denoting compliance with national electromagnetic interference 
(emissions) requirements. 
Prevent Power Supply Overload 
Do not overload the power supply output.  To avoid overloading the power supply, make sure that 
the calculated total current loads of all the modules within the computer is less than the output 
current rating of each of the power supplies output circuits.   
Place Battery Marking  
 CAUTION 
Risk of explosion if the battery is replaced with an incorrect type.  Batteries should be recycled 
where possible.  Disposal of used batteries must be in accordance with local environmental 
regulations. 
 
There is insufficient space on this Desktop Board to provide instructions for replacing and 
disposing of the Lithium ion coin cell battery.  For system safety certification, the following 
statement or equivalent statement is required to be permanently and legibly marked on the chassis 
near the battery.
