2 Installation
Connecting the Power Cord
FIRE HAZARD Use only the power cord that was supplied with your 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 Keysight 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.
Keysight N6702C 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 mains
circuits will not be overloaded.
The detachable power cord may be used as an emergency disconnecting device.
Removing the power cord will disconnect AC input power to the unit.
Snap-on Ferrite core for N6700C
Installing the supplied ferrite core is only necessary if you are connecting highly sensitive loads to the
output of the N6700C. The purpose of the ferrite core is to reduce the possibility of common mode
current spikes appearing at the output of the power system when AC power is switched on or off. Note
that N6701C and N6702C mainframes have built-in ferrite cores.
Additional measures to protect sensitive loads from common mode currents are discussed under
Protecting Sensitive Loads from AC Power Switching
To install the core:
1. Locate the core anywhere along the cord.
2. Pass the power cord through the core twice.
3. Close the core.
