Safety Considerations
This instrument may be damaged if operated with
the Line Voltage Selector switch or the Regulating
Range Selector switch set for the wrong applied line
voltage or if the wrong line fuse is used.
Refer to the Safety Summary in the front of this manual
for power source, grounding, and other
safety con-
siderations pertaining to use of the instrument. Before
connecting the instrument to a power source, verify that
the Line Voltage Selector switch and the Regulating
Range Selector switch are both set for the line voltage
being used, that the proper line fuse is installed, and that
the line cord plug matches the power source to be used.
The 442 is designed to be used with-a three-wire ac
power system.
If a three-to-two wire adapter is used to
connect this instrument to a two-wire ac power system, be
sure to connect the ground lead of the adapter to earth
(ground). Failure to complete
the ground system may
allow the chassis of this instrument to be elevated above
ground potential, thus posing a shock hazard.
