Connecting the Line Cord

	FIRE HAZARD Use only the power cord that was supplied with your
WARNING
	instrument. Using other types of power cords may cause overheating of the
	power cord, resulting in fire.
	SHOCK HAZARD The power cord provides a chassis ground through a third
	conductor. Be certain that your power outlet is of the three-conductor type
	with the correct pin connected to earth ground.
	Connect the power cord to the IEC 320 connector on the rear of the
	unit. If the wrong power cord was shipped with your unit, contact
	your nearest Agilent Sales and Support Office.
	The AC input on the back of your unit is a universal AC input. It
	accepts nominal line voltages in the range of 100 VAC to 240 VAC.
	The frequency can be 50 Hz, 60 Hz, or 400 Hz.
	Agilent N6702A Mainframe Note: Standard AC mains circuits rated
	at nominal 100-120 VAC cannot supply enough current to power the
	N6702A mainframe when it is operated at its full rated power.
	Nevertheless, the N6702A can be connected to an AC mains circuit
	rated at nominal 100-120 VAC. In this case, internal circuits will limit
	the power available to modules to 600 W. As a result of this power
	limiting, the current drawn from the AC mains will be < 15 A, so that
	standard 100-120 VAC AC mains circuits will not be overloaded.
	The detachable power cord may be used as an emergency disconnecting
NOTE
	device. Removing the power cord will disconnect AC input power to the unit.

Snap-On Ferrite Core

Installing the ferrite core is only necessary if you are connecting highly sensitive loads to the output of the modular power system. The purpose of the ferrite core is to reduce the possibility of common mode current spikes appearing at the output of the modular power system when AC power is switched on or off.

Additional measures to protect sensitive loads from common mode currents are discussed under “Protecting Sensitive Loads from AC Power Switching Transients” later in this chapter.

Installation

Locate the core anywhere along the length of the cord.

Pass the power cord through the core twice.

Close the core.
