Line Voltage Conversion
Warning Shock Hazard Operating personnel must not remove power supply covers.
Component replacement and internal adjustments must be made only by qualified
service personnel.
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 AC line power.
2 Remove the cover (Refer to General Disassembly on page 178).
3 Set two sections of the line voltage selector switch on the PC board for the desired
line voltage (See Figure 1-1 below).
4 See the next page 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.
