Line Voltage Wiring
Figure 3-3 illustrates the primary wiring configuration of the power transformer for various ac line voltages. Use long nose pliers to disconnect the wires going to the transformer terminals.
NOTE: Install the correct fuse when changing the ac line voltage from a previous setting: for 110/120 Vac: 2.5AT, 250V, Agilent p/n
for 220/230 Vac: 1.25AT, 250V, Agilent p/n 2110-0788
