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