Preparing for Use and Printing
Power Requirements
WARNING
For continued protection against fire hazard, replace the line
fuse only with the same type and rating. The use of other fuses
or material is prohibited.
Power Cable
The spectrum analyzer is equipped with a three-wire power cable, in
accordance with international safety standards. When connected to an
appropriate power line outlet, this cable grounds the instrument
cabinet.
WARNING
Failure to ground the spectrum analyzer properly can result in
personal injury. Before turning on the spectrum analyzer, you
must connect its protective earth terminals to the protective
conductor of the main power cable. Insert the main power cable
plug only into a socket outlet that has a protective earth
contact. DO NOT defeat the earth-grounding protection by
using an extension cable, power cable, or autotransformer
without a protective ground conductor.
If you are using an autotransformer, make sure its common
terminal is connected to the protective earth contact of the
power source outlet socket.
Various power cables are available to connect the spectrum analyzer to
the types of ac power outlets unique to specific geographic areas. The
cable appropriate for the area to which the spectrum analyzer is
originally shipped is included with the unit. You can order additional ac
power cables for use in different areas. The following table lists the
available ac power cables, illustrates the plug configurations, and
identifies the geographic area in which each cable is appropriate.
