(2) Please contact your Kontron representative for detailed information on specific peripherals
support (e.g. DVD-ROM drive) .
(3) The maximum room temperature is 45°C. Continued operation at this temperature may
degrade hardware performance. It is advisable, therefore, to install a supplementary air
conditioning system in the room if temperature of the site is greater than that recommended.
(4) The front panels of the Kontron boards are equipped with an EMC gasket. To preserve the
gaskets and to prevent that the components of the boards could be damaged by contact with
gaskets, it is mandatory:
DWhen the boards are horizontal, insert them downward. To unplug the boards proceed in the
inverse sense of the insertion.
(5) This material is a class A material. In a residential environment, this material can cause radio

2.1 Technical Recommendations
Recommendation
Avoid connecting your rack on the same circuit as any electrical equipment that does not have a noise
suppressor, and can produce transient phenomena.
It is preferable to install a separate power line directly from the main electrical network.
All the system components (peripheral rack, printer, etc.) must be connected directly to the main
electrical network.
Power Supply
Check the correct input voltage prior applying power to the unit. Refer to Table 2 Main Characteristics",
section Power Supply Unit PSU".
Electrical safety
To prevent electrical accidents that could damage your equipment and threaten user safety, adhere to
the regulations and standards recommended in the IEC publication 364 (International Electronic
Commission) and the French standard NFC 15-100.
Electrical Damage
Avoid connecting cables to the front panel application connectors while functioning. Voltage discharge
may damage the inserted boards I/O devices or the power supply.
Fire safety
Fire estinguishers, type CO2, should be installed in the work area, close to the rack.
User Safety
All fans are externally protected with proper finger guard grids. User should avoid touching any fan part
with his fingers.
DO NOT turn the power on while the power is cycling off. Wait a few seconds until the power has
completely cycled off. Follow the same precaution for turning the power off.
Turning the power on or off before this cycle is complete can cause the voltage and temperature values
programmed into the board monitoring system to be lost.
MAKE SURE YOU FOLLOW THESE SAFETY PRECAUTIONS.
Make sure the rack has been powered off using the ON/OFF button (on the front control panel of the rack)
before unplugging the power supply cable.
It is strongly recommended to use an antistatic wrist strap and a conductive foam pad when you install or
upgrade your system to prevent the accumulation of electrostatic charges.
Avoid touching areas of integrated circuitry; static discharge can damage circuits.
