Installing the 2606B
The 2606B is intended for mounting in a rack only. For detailed instructions, refer to the
documentation for the Model 4299-13 Rack Mount Kit (part number 0713574).
Rack mounting the 2606B requires two people. Failure to recognize and observe standard
safety precautions could result in personal injury.
Cooling vents
The 2606B has front and side intakes and rear exhaust vents. All sides must be unobstructed to allow
for air flow and to dissipate heat.
Excessive heat could damage the 2606B and degrade its performance. Only operate the 2606B in an
environment where the ambient temperature does not exceed 50 °C.
To prevent damaging heat build-up and ensure specified performance, use the following
guidelines.
The rear exhaust vents and both side intake vents, and the front intake vents must be
unobstructed to properly dissipate heat. Even partial blockage could impair proper
cooling.
Do not position any devices adjacent to the 2606B that force air (heated or unheated)
toward its cooling vents or surfaces. This additional airflow could compromise accuracy.
When rack mounting the 2606B, make sure there is adequate airflow around both sides of
the instrument to ensure proper cooling. Adequate airflow enables air temperatures
within approximately one inch of the 2606B surfaces to remain within specified limits
under all operating conditions.
The front and sides of the 2606B are cool air intakes. It is recommended that there is
23 °C ±5 °C air available at these locations. The rear of the 2606B is the exhaust.
If you rack mount high power-dissipation equipment next to the 2606B, it could cause
excessive heating. To produce specified 2606B accuracies, maintain the specified
ambient temperature around the intake vents of the 2606B. In rack configurations with
convection cooling only, which is not recommended, proper cooling practice places the
hottest non-precision equipment (for example, the power supply) at the top of the rack
away from and above precision equipment (such as the 2606B).
Mount precision equipment as low as possible in the rack, where temperatures
are coolest.
