1 General Information Document Orientation This manual describes the operation of the Agilent Technologies 6814B/6834B/6843A AC Power Solutions. These units will be referred to as "ac sources" throughout this manual. Operation of the Agilent 6843A is described for normal mode operation only. The following documents are shipped with your ac source: ♦ a Quick-Start Guide, to help you quickly get started using the ac source ♦ a User’s Guide, containing detailed installation, checkout, and front pa

1 - General Information Safety Considerations This ac source is a Safety Class 1 instrument, which means it has a protective earth terminal. That terminal must be connected to earth ground through a power source equipped with a ground receptacle. Refer to the Safety Summary page at the beginning of this guide for general safety information. Before installation or operation, check the ac source and review this guide for safety warnings and instructions. Safety warnings for specific procedures are

General Information - 1 Description The ac source combines three instruments in one unit as shown in the following figure. The function generator produces waveforms with programmable amplitude, frequency, and shape. The power amplifier amplifies the function generator signal to produce the ac power for your application. The measurement functions range from a simple readback of rms voltage and current, to sophisticated capabilities such as waveform analysis. shunt SOURCE DAC BIPOLAR MEASUREMENT

Installation - 2 Input Connections Input Source and Line Fuse The ac source requires a 3-phase power service that provides 7350 VA (6000 W) maximum. The power service should have a current rating greater than or equal to the ac source’s circuit breaker rating. The ac source has a delta input (no neutral connection) and will accept power from either delta (triangle) or wye (star) services. CAUTION: Two input voltage ranges are available (see "AC Input Ratings" in appendix A). The ac source will

Installation - 2 NOTE: To minimize the possibility of instability on the output, keep load leads as short as possible bundle or twist the leads tightly together to minimize inductance Wire Considerations Current Ratings Fire Hazard To satisfy safety requirements, load wires must be large enough not to overheat when carrying the maximum short-circuit current of the ac source. If there is more than one load, then any pair of load wires must be capable of safely carrying the full-rated current of

2 - Installation Remote Sense Connections Under normal operation, the ac source senses the output voltage at the output terminals on the back of the unit. External sense terminals are available on the back of the unit that allow the output voltages to be sensed at the load, compensating for impedance losses in the load wiring. As shown in the following figure: ♦ Connect the phase 1 (ϕ1) through phase 2 (ϕ) sense terminals to the side of the load that connects to the corresponding output terminal
