Cooling vents

The Series 2600 has side intake and rear exhaust vents. One side must be unobstructed when
rack mounted to dissipate heat. NEVER place a container of liquid (water or coffee for instance) on
the top cover. If it spills, the liquid will enter the case through the vents and cause severe damage.
Excessive heat could damage the Series 2600 and degrade its performance. The Series 2600
must be operating in an environment where the ambient temperature does not exceed 50°C.

To prevent damaging heat build-up and ensure specified performance,
adhere to the following precautions:
The rear exhaust vent and at least one side vent must be kept free of any
obstructions. Even partial blockage could impair proper cooling.
The rear exhaust vent and at least one side vent must be kept free of any
obstructions. Even partial blockage could impair proper cooling.
DO NOT position any devices adjacent to the Series 2600 that force air
(heated or unheated) into or onto its cooling vents or surfaces. This
additional airflow could compromise accuracy performance.
When rack mounting the Series 2600, make sure there is adequate airflow
around at least one side to ensure proper cooling. Adequate airflow enables
air temperatures within approximately one inch of the Series 2600 surfaces
to remain within specified limits under all operating conditions.
Rack mounting high power dissipation equipment adjacent to the Series
2600 could cause excessive heating to occur. The specified ambient
temperature must be maintained around the surfaces of the Series 2600 to
specified accuracies. A good measure to ensure proper cooling in rack
situations with convection cooling only is to place the hottest equipment (for
instance, the power supply) at the top of the rack. Precision equipment
(such as the Series 2600) should be placed as low as possible in the rack
where temperatures are coolest. Adding space panels below the Series
2600 will help ensure adequate air flow.
