Line Wiring

The power supply requires a 3-phase power source that provides 7350 VA (6000 W) maximum. The power supply has a

delta input (no neutral connection) and will accept power from either delta (triangle) or wye (star) sources. Two voltage

ranges are available (see "AC Input Ratings" in Table 1-4a). In order to maintain phase current balancing, the power

source should be a dedicated line with only Agilent Technologies Series 668xA supplies drawing current from it. A

disconnect box located near the power supply (see Figure 2-4) is recommended for all installations and is mandatory for

direct-wired installations.
