Converting line voltage
Line voltage conversion is accomplished by adjusting two components: the line
voltage selection switch and the power-line fuse on the rear panel.
1 Remove the AC line power.
2 Remove the cover. “General Disassembly” on page 198.
3 Set the two sections of the line voltage selector switch on the PC board for the
desired line voltage. Refer to Figure 1-2.
4 Refer to “Replace the power-line fuse” on page 37 to check the rating of the
power-line fuse and replace with the correct one if necessary.
5 Replace the cover and mark the power supply clearly with a tag or label
indicating the correct line voltage and fuse that is in use.
