Follow the instructions described for the applicable single board computer to connect a power supply unit, boot
up the boards, configure the BIOS and mount the boards in chassis. In case the power supply is input from the
power terminal block on the 3.5’’-eIO-GPA, DC power voltage should be within the range between 11 V and 32 V.
Make sure to turn off PSU (Power Supply Unit) completely (no mains power connected to
the PSU) or leave the Power Connectors unconnected before connecting to the PSU.
Otherwise, components (RAM, LAN cards etc.) on the 3.5’’-eIO-GPA and the applicable
single board computer might get damaged.
The power supply unit shall comply with the requirements as defined in IEC 62368-1
according Clause 6.2.2 to power source category PS2 "Limited Power Source".

Chassis Safety Standards
Before installing the 3.5"-eIO-GPA and the applicable single board computer in the chassis, users must evaluate the
end product to ensure compliance with the requirements of the IEC60950-1 safety standard:
The boards 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 board must be powered by a CSA or UL approved power supply that limits the maximum input current.
For interfaces having a power pin such as external power or fan, ensure that the connectors and wires are
suitably rated. All connections from and to the product shall be with SELV circuits only.
Wires have suitable rating to withstand the maximum available power.
The peripheral device enclosure fulfils the IEC60950-1 fire protecting requirements.
