    Quick Guide 3 Mechanical Installation 3.1 Overview VLT 2800 frequency converters allow side-by-side instal- lation on a wall in any position as the units do not require ventilation on the side. Because of the need for cooling, there must be 100 mm free air passage above and below the frequency converter.
