Ensuring cooling air
The cooling air for the power unit is drawn in from the front through the ventilation grilles in the
cabinet doors. The warmed air is expelled above the fan through the perforated top cover or the
ventilation grilles in the top cover.
Make sure that the air that is supplied is free of dust or any other electrically conductive
material. Avoid environmental conditions that could cause condensation. Seal the cable
connector panels from the top.
