Ventilation requirements: When installing the product in a
cabinet, the convection into and out of the product must not be
restricted. The ambient temperature (outside the cabinet) must be
less than the maximum operating temperature of the product by
4 °C for every 100 watts dissipated in the cabinet. If the total
power dissipated in the cabinet is greater than 800 watts, then
forced convection must be used.
