Cabinet Installation; Preventing Cooling Air Recirculation - ABB ACS800 Hardware Manual

into a cabinet. The required distance between parallel units is five millimetres
(0.2 in.) in installations without the front cover. The cooling air entering the unit must
not exceed +40 °C (+104 °F).

Preventing cooling air recirculation

Prevent air recirculation inside and outside the cabinet.
