AC Power Cable
The 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 analyzer properly can result in personal
injury. Before turning on the 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 analyzer to the types
of ac power outlets unique to specific geographic areas. The cable
appropriate for the area to which the 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.
