Chassis Safety Standards
Take care when designing chassis interface connectors in order to fulfil the IEC60950-1 standard. 3.5-SBC-APL users
must evaluate the end product to ensure compliance the requirements of the IEC60950-1 safety standard are met:
The motherboard must be installed in a suitable mechanical, electrical and fire enclosure.
The system in its enclosure must be evaluated for temperature and airflow considerations.
The motherboard must be powered by a CSA or UL approved power supply that limits the maximum input current
to 15 A via internal square ATX +12 V 4-pin connector.
For interfaces having a power pin such as external power or fan, ensure that the connectors and wires are
suitably rated. All connections from/to the product shall be with SELV circuits only.
Wires have suitable rating to withstand the maximum available power.
The enclosure of the peripheral device fulfils the fire protecting requirements of IEC60950-1.
Danger of explosion if the lithium battery is incorrectly replaced.
Replace only with the same or equivalent type recommended by the manufacturer
Dispose of used batteries according to the manufacturer’s instructions
