Installing the Power-Line Fuse
WARNING
FOR POWER-LINE VOLTAGES OF 198V TO 250V, THE POWER-
LINE FUSE MUST BE REPLACED WITH A 1/8A, 250V SLO-BLO
FUSE FOR FIRE PROTECTION. TO AVOID ELECTRIC SHOCK,
REMOVE THE POWER CORD BEFORE REPLACING THE
EXTERNAL LINE FUSE.

The 8842A has a rear-panel power-line fuse in series with the power supply. A 1/4A,
250V slow-blow fuse is installed in the factory for operation from 90V to 132V. For
operation with power-line voltages of 198V to 250V, the fuse must be replaced with a
1/8A, 250V slo-blow fuse.

The 8842A can be configured to accept line power of 100, 120, 220, or 240V ac (+/-10%,
250V maximum) at 50, 60, or 400 Hz. The voltage must be selected by setting the rear
panel LINE SET switches as shown in Figure 2-1. The 8842A automatically senses the
power-line frequency at power-up, so that no adjustment for frequency is necessary.
