Preparing For Use

 

The cable TV 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.

Failure to ground the cable TV analyzer properly can result in personal
injury. Before turning on the cable TV 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 cable TV analyzer to the
types of ac power outlets unique to specific geographic areas. The cable
appropriate for the area to which the cable TV analyzer is originally shipped
is included with the unit. You can order additional ac power cables for use

in different areas.
