Power Cable
The 11974-60028 Preselector Power Supply is equipped with a three-wire power cable, in
accordance with international safety standards. When connected to an appropriate
power-source outlet, this cable grounds the instrument cabinet.
WARNING
Failure to ground the instrument properly can result in personal
injury. Before turning on the preselector power supply, 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 auto transformer. Make sure its common terminal is
connected to the protective earth contact of the power source socket.
Various power cables are available to connect the power supply to the types of ac power
outlets unique to specific geographic areas. The cable appropriate for the area to which the
power supply 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.
