The procedure for changing the input line voltage is as
follows.
1 Remove the power card from the ac input socket on
the back of the power supply.
2 To open the power module, move the plastic door on
the module aside. If your line voltage change
requires a change in rating of the fuse, rotate FUSE
PULL to the left and remove the fuse (see
Figure
11-4 on page 11-14).
3 Grasp the voltage selector PC board with a pair of
needle-nose pliers and slide it out of its slot.
4 To select a voltage, orient the PC board so that the
desired voltage appears on the top left side of the
board (see
Figure 11-4 on page 11-14). Push the
board all the way back into its slot.
The desired line voltage must be visible through the
module window when the board is installed.
