Figure 2-1 Line Voltage Selection
WARNING To avoid the possibility of hazardous electrical shock, do not
operate this Instrument at line voltages greater than 126.5 Vac
with line frequencies greater than 66 Hz (leakage currents at
these line settings may exceed 3.5 mA).
❏ Line Voltage and Fuse Selection
a. Open the cover door of the line power module. Push the fuse-pull
lever to the left and remove the fuse. (Refer to Figure 2-1.)
b. Pull out the voltage selector PC board. Position the board so that the
voltage nearest the actual fine voltage level is on the top-left side of
the board.
c. Push the board firmly into the module slot.
d. Push the fuse-pull back into normal right-hand position.
e. Check that the fuse is the correct rating and type for the input ac
line voltage. Fuse ratings for line voltages are indicated below the
power module.
f. Insert the fuse into the holder.
