Installation
Preparation for Use
Power Cord
TO AVOID THE POSSIBILITY OF INJURY OR DEATH, THE
FOLLOWING PRECAUTIONS MUST BE FOLLOWED BEFORE
THE INSTRUMENT IS SWITCHED ON:-
(a) Note that the protection provided by grounding the
instrument cabinet may be lost if any power cable other than the
three-pronged type is used to couple the ac line voltage to the
instrument.
(b) If this instrument is to be energized via an auto-transformer
to reduce or increase the line voltage, make sure that the common
terminal is connected to the neutral pole of the power source.
(c) The power cable plug shall only be inserted into a socket
outlet provided with a protective ground contact. The protective
action must not be negated by the use of an extension cord
without a protective conductor (grounding).
The power cord supplied with each instrument varies with the country of
destination. The following figure illustrates the standard power plug
and cord configurations that are commonly used. The part number
shown beneath each plug is the part number of the appropriate power
cord and plug. If the appropriate power cord is not included with the
instrument notify the nearest Hewlett-Packard office and a replacement
will be provided.
