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 be damaged if it is operated at an input voltage that is outside of its configured input range.

In order to maintain phase current balancing, the power service should be a dedicated line with only Agilent 6814B/6834B/6843A ac sources drawing current from it. A disconnect box located near the ac source is recommended for all installations and is mandatory for direct-wired installations.

Installing the Power Cord

WARNING: Installation of the power cord must be done by a qualified and licensed electrician and must be in accordance with local electrical codes.

The power cords supplied with the ac source do not include a power plug. Terminating connectors and a ground lug are attached to one end of the cord. See Figure 2-2 while performing the following procedure.

1.Check the line fuses as follows:

a.Examine the FUSES label on the rear panel.

b.Remove the safety cover in front of the fuse caps.

c.Unscrew the line fuse caps from the rear panel and verify that all fuses are as specified on the label. Reinstall the fuses.

d.Reinstall the safety cover in front of the fuse caps.

2.Remove the ac input cover from the back of the unit.

3.Open the line clamp on the ac input cover and insert the line cord through the opening.

4.Position the power cord so that the clamp is near the end of the outside insulating sheath on the power cord. Tighten the screws to secure the clamp.

5.Secure the three ac lines to the ac power strip as follows:

Phase 1 to L1 (black).

Phase 2 to L2 (red).

Phase 3 to L3 (orange).

6.Secure the ground wire (green) to the chassis earth ground terminal.

7.

Slip the safety cover over the ac input terminal strip and secure the cover with the four

 

screws.

8.If required, wire the appropriate power plug to the other end of the power cord. For user- made cables, strip back the sheath 10 cm (4 in).
