2-10. BATTERY.

2-6. This set is designed to operate from an internal 45 volt dry cell battery, an external 24 to 48 volt CO battery or from an ac power source (115/230V, 48 to 440Hz). The power source is selected by the AC/BAT switch on the side of the, set. The line voltage is selected by the 115/230 volt slide switch on the rear of the set. The set is protected by a 0.1 5A slow-blow fuse.

2-7. THREE-CONDUCTOR POWER CABLE.

2-8. To protect operating personnel, the National

Electrical Manufacturers' Association (NEMA) recommends that the panel and cabinet be grounded. This set is equipped with a three-conductor power cable which, when plugged into an appropriate receptacle, grounds the set. The offset pin on the power cable three-prong connector is the ground wire. This power cable is detachable from the set and is stored inside the front cover.

2-9. Figure 2-1illustrates the standard power plug configurations that are used throughout the United States and in other countries. The -hp- part number shown directly below each plug drawing is the part number for a 3555B power cord equipped with the proper plug. If the appropriate power cord is not included with the instrument, notify the nearest Hewlett- Packard office and a replacement cord will be provided.

2-11. This set is operated from a single NEDA 202 45V dry cell internal battery or an external 48V CO battery when the power selection switch, on the side of the case, is in the DIAL/BAT position. Inserting a Western Electric plug into the battery jack disconnects the internal battery. (See Table 2-1for batteries suitable for use in this instrument.
