Chapter 2 Installation
Mounting Clearances When selecting an installation site for the computers, be sure to allow adequate
clearance on the sides and rear of the computer for proper ventilation, cable
connection, and hardware access. Sufficient airflow throughout the system unit is
required to maintain proper cooling. Clearance should be enough to allow
convenient installation or removal of peripheral components, such as the
CompactFlash card.
IMPORTANT Use adequate ventilation or other cooling methods to maintain the
product temperature at its specified rating.
Because of self-heating, do not operate the computer in an enclosure by
using the minimum clearances unless adequate ventilation or other
cooling methods are used to lower the temperature within the enclosure.
The minimum required enclosure size (HxWxD) is 403 x 497 x 154 mm
(15.87 x 19.57 x 6.06 in.).
