Installing the Series 668xA Power Cord

The Series 668xA power supply requires a 3-phase power source that provides 7350 VA (6000 W) maximum. The 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/669xA 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.

Installation of the power cord must be done by a qualified electrician and in accordance with local electrical code.

The power cords supplied with the power supply do not include a power plug (see "Options" in Chapter l) at one end of the cord. Terminating connectors and a ground lug are attached to the other end of the cord.

See Figure 2-5 and proceed as follows:

l. Check the line fuses ( , Figure 2-5) as follows:

a. Examine the LINE RATING label on the rear panel.

b. Unscrew the line fuse caps ( from the rear panel and verify that all fuses are as specified on the label. Replace the fuses.

2.Open the line clamp and insert the line cord through the opening.

3.Position the line cord so that the clamp is near the end of the outside insulating sheath. Tighten the screws securing

the clamp.

 

 

 

 

 

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

 

* Phase 1

to L1.

Phase 2

to L2.

Phase 3

to L3.

5. Secure the ground wire to the chassis earth ground stud.

Do not connect anything to the terminal marked "DO NOT USE".

6.Slip the safety cover over the fuses and terminal strip and secure the cover with the four capscrews.

7.If required, wire the appropriate power plug to the other end of the power cord.

Note

For user-made cable , strip back sheath 100 mm (3.9 in).
