b. Perform Steps (b) through (e) of Paragraph
2-22.
2-25CONNECTIONS FOR 50Hz OPERATION
2-26 For operation from a 50Hz ac input, R82 must be replaced with a 240 Ω, ±5%, ½ watt resistor as specified under Option 005 in Table 6-4(Re- placeable Parts). In addition, it is necessary to readjust the voltage drop across the series regulator (“Preregulator Tracking” , Paragraph 5-103)and to check the ripple imbalance as described in Steps
(a)through (e) of Paragraph 5-101.2-27POWER CABLE
2-28 A power cable is not supplied with the in- strument. It is recommended that the user-supplied power cable have three conductors (third conductor
grounded) and be of sufficient wire size to handle the input current drawn by the supply (see Paragraph 2-16). Note that when the supply is operated from a 115Vac source, the input current is approximately double that shown in Paragraph 2-16.
2-29REPACKAGING FOR SHIPMENT
2-30 To insure safe shipment of the instrument, it is recommended that the package designed for the instrument be used. The original packaging material is reusable. If it is not available, contact your local Hewlett-Packard field office to obtain the materials. This office will also furnish the address of the nearest service center to which the instrument can be shipped. Be sure to attach a tag to the instrument specifying the owner, model number, full serial number, and service required, or a brief description of the trouble.
