Input Power Requirements
You can operate this power supply from a nominal 100 V, 120 V, 220 V or 240 V single phase power source at 47 to 66
Hz. The input voltage range, maximum input current, high line inrush current (PK), and the fuse required for each of the
nominal inputs are listed in Table 2-1. You can check the line voltage setting of your supply by examining the door on the
line module. This is located on the rear panel of your supply as shown in Figure 2-2.
If necessary, you can convert the supply from one line voltage setting to another by following the instructions under Line
Voltage Conversion (page 28).

Line Fuse
The ac line fuse is located behind the door on the line module (see Figure 2-3). To access the fuse, remove the power cord
and push against the tab on the line module in the direction of the ac input socket. The current rating of the fuse is based
on the line voltage setting of your supply. Table 2-2 gives the HP part numbers for the fuses that should be used with
specific line voltages.
