If the power supply and other modules or peripherals, as applicable, are not Class B EMC
compliant before integration, then EMC testing may be required on a representative sample of the
newly completed computer.
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.
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 above statement or
equivalent statement is required to be permanently and legibly marked on the chassis near the
battery.
