2 Installation30 Keysight N6700 User’s GuideConnecting the Line CordWARNING FIRE HAZARD Use only the power cord that was supplied with yourinstrument. Using other types of power cords may cause overheating ofthe power cord, resulting in fire.SHOCK HAZARD The power cord provides a chassis ground through athird 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 yournearest Keysight Sales and Support Office.The AC input on the back of your unit is a universal AC input. It acceptsnominal line voltages in the range of 100 VAC to 240 VAC. The frequencycan be 50 Hz, 60 Hz, or 400 Hz.Keysight N6702A Mainframe Note: Standard AC mains circuits rated atnominal 100-120 VAC cannot supply enough current to power theN6702A mainframe when it is operated at its full rated power.Nevertheless, the N6702A can be connected to an AC mains circuitrated at nominal 100-120 VAC. In this case, internal circuits will limit thepower 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 standard100-120 VAC mains circuits will not be overloaded.NOTE The detachable power cord may be used as an emergency disconnectingdevice. Removing the power cord will disconnect AC input power to theunit.
