Temperature Performance

A variable-speed fan cools the supply 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 temperature performance is as follows:
Series 654xA/655xA
Series 657xA

Input Power Source

Refer to the applicable paragraphs below for information on the input power source. Do not apply power to the power
supply until directed to do so in Chapter 3.
Check the line
corresponds to the nominal line voltage of your power source. If it does not, see Appendix B for
instructions on changing the power supply's line voltage configuration.
Series 654xA and 655xA
You can operate your supply from a nominal 100 V, 120 V, 220 V, 230 V, or 240 V single-phase ac power source as
indicated on the rear panel line Rating label. See "AC Input Ratings" in Table 1-la for the voltage and frequency range for
each type of power source. "Maximum AC Line Current Ratings" in Table 1-2a shows the required current load. The line
fuse is located in a fuseholder on the rear panel (see Figure 2-1). The Line Fuse label on the rear panel shows the fuse value
used in the power supply and Table 1-4 identifies the replacement fuse.
Series 657xA
Input Source and Line Fuse
You can operate your supply from a nominal 200 or 230 volt single-phase ac power source as indicated on the rear panel
Line Rating label. See "AC Input Ratings" in Table 1-lb for the voltage and frequency range for each nominal power
source. "Maximum AC Line Current Ratings" in Table 1-2b shows the required current load.
