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 label on the rear of your supply and verify that the voltage shown there
corresponds to the nominal line voltage of your power source. If it does not, see "Appendix C - Line
Voltage Conversion" for instructions on changing the power supply’s line voltage configuration.
Series 664xA and 665xA Supplies
The supplied cord connects to the power receptacle on the rear panel ( 2, Figure 2-l).
■ You can operate your supply from a nominal l00 V, 120 V, 220 V, 230 V, or 240 V single-phase ac power source as
indicated on the rear panel line label 1.
■ See "AC Input Ratings" in Table l-la or Table 1-2a for the voltage and frequency range for each type of power source.
"Maximum AC Line Current Ratings" in Table l-lb or Table 1-2b show the maximum load current.
■ The line fuse is located in a fuseholder on the rear panel 3. The rear panel label 1 shows the fuse value used in the
power supply and Table 1-6 identifies the replacement fuse.

Note This product requires single-phase input voltage.
You can operate your supply from a nominal 200 V or 230 V, single-phase power source, or from the line-to-line voltage of
a 208-volt, 3-phase source. The proper source is indicated on the rear label ( 4, Figure 2-2). See "AC Input
Ratings" in Table 1-3a for the voltage and frequency range for each type of power source.
Note The power source must be a dedicated line with no other devices drawing current from it.
The line fuse is located inside the power supply. Table 1-6 identifies the replacement fuse. See "In Case of Trouble" in
Chapter 3 for instructions on fuse replacement.
