2 Review Safety Requirements

2. 7 Ventilation

VENTILATION REQUIREMENTS: When installing the product into a
cabinet, the convection into and out of the product must not be
restricted. Consideration shall also be given to the individual
instruments to avoid having the heated discharge of one
instrument, now becoming the cooling intake air for another
instrument.
Another area of concern is verification that the maximum ambient
operating temperature of the instrument(s) is not exceeded by
cabinet installation.
Keysight recommends forced air convection whenever
instrument(s) are installed in a cabinet and further recommends
that the maximum operating temperature of the cabinet be
reduced 10°C from the lowest, of the maximum operating
temperature of a single instrument.
If there are any concerns or special requirements, a Keysight Field
Engineer should be consulted to assure instrument(s)
temperature compliance and performance.
Do NOT block vents and fan exhaust: To ensure adequate
cooling and ventilation, leave a gap of at least 50 mm (2") around
vent holes on both sides of the chassis.
