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 RATING 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.

Installing the Series 664xA and 665xA Power Cord

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 RATING 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	The detachable power cord may be used as an emergency disconnecting device. Removing the power cord
	from the ac input connector will disconnect ac input power to the unit.
Installing the Series 667xA Power Cord

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

a208-volt, 3-phase source. The proper source is indicated on the rear line RATING 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.

Installation of the power cord must be done by a qualified electrician and in accordance with local electrical codes.
