3.3 Mechanical Installation
The Sequoia/Tahoe Series are completely self-contained power sources. They are to be used free
standing on a solid surface. The units are fan cooled, drawing air in from the front and exhausting at the
rear. Each unit must be kept clear of obstruction with a 12” clearance on the rear and 6” clearance on both
the left and right sides of the unit. Special consideration of overall air flow characteristics and the resultant
internal heat rise must be always considered to avoid self-heating and over temperature problems.
