5
Install the correct fuse in the door of the line module
if your line voltage change also requires a change in
the rating of the fuse (see
WARNING
✸
Make sure the replacement fuse type (size) and
rating (current, speed, and voltage) is consistent
with the voltage level you are operating at. Using
a substitute fuse could result in a fire hazard.

Close the door of the line module and insert the
power cord in the ac input socket. Your power
supply is now configured to operate at the voltage
you selected.
Agilent 6634A Line Voltage Settings
The 6634A supply can be set to accept 100, 120, 220 or
240 volts ac input. You can convert line voltage by
setting three components: two line select switches (S2
and S3) and the rear panel fuse (F1). To convert the
supply from one line voltage to another, proceed as
follows:
1
Turn off the supply and use a #2 Pozidriv screwdriver
to remove the top cover by removing five screws:
two M5 on each side and one M4 on the rear panel.
2
Locate the line voltage select switches S2 and S3 (see
