Damage caused by overheating resulting from covered ventilation slots
Covered ventilation slots can cause the system to overheat.
• Route the connected signal and power cables to the components in such a way that
they do not cover the ventilation slots.
Note
The distance between the discharge ope
ning of the air condition equipment and the
electronic equipment must be at least 200
mm.
Note
If the components are mounted in a sealed cabinet, an internal air cooling system must be
installed to circulate the air and prevent hot spots. It is best to
mount the fan above the
components to optimize the air flow (suction).
