20 Installation
Rack Mounting
The Agilent SAS can be mounted in a standard l9-inch rack panel or cabinet. Rack mounting kits are available as Option
908 or 909 (with handles). Installation instructions are included with each rack mounting kit.
Support rails are required when rack-mounting the Agilent SAS (see table 1-1).
Temperature Performance
A variable-speed fan cools the unit by drawing air through the sides and exhausting it out the back. Using Agilent rack
mount or slides will not impede the flow of air. The Agilent SAS operates without loss of performance within the
temperature range of 0 °C to 40 °C and with derated output current from 40 °C to 55 °C (see appendix A).
If the Agilent SAS is operated at full output current for several hours, the sheet metal immediately under
the transformer (near the right front) can get very hot. Do not touch this area of the cabinet. The line
cord also can become quite warm. Both of these conditions are normal.
AC Line Connection
Refer to the applicable paragraphs below for information on the ac line. Do not apply power to the Agilent SAS until
directed to do so in Chapter 3.
Check the line Rating label on the rear of your unit and verify that the voltage shown there
corresponds to the nominal line voltage of your ac line. If it does not, see AC Line Voltage Conversion
for instructions on changing the Agilent SAS line voltage configuration.
The supplied cord connects to the power receptacle on the rear panel (
, Figure 2-l).
You can operate your Agilent SAS from a nominal 100 V, 120 V, 220 V, 230 V, or 240 V single-phase ac line as
indicated on the rear panel line Rating label
.
See "AC Input Ratings" in table A-l or table A-2 in appendix A for the voltage and frequency range for the Agilent
SAS. Refer to "Maximum AC Line Current Ratings" for the maximum load current.
The line fuse is located in a fuseholder on the rear panel
. The rear panel label shows the fuse value used in the unit.
See Operator Replaceable Parts in chapter 1 for replacement fuse information.
