3.3 Mechanical Installation
3.3.1 Table top
The iX/i Series AC power sources can be used free standing on a solid surface or mounted in a 19"
instrument cabinet. The units are fan cooled, drawing air in from the side and exhausting at the rear.
The back of each unit must be kept clear of obstruction and a 3" clearance must be maintained to the
rear. Special consideration of overall airflow characteristics and the resultant internal heat rise must
be considered at all times to avoid self heating and over temperature problems.
