Figure 2-2.Bias Transformer Primary Connections for 208Vac Operation (Model 6259B, 6260B, 6261B, 6268B, and 6269B) and 115Vac Operation

(Except Model 6269B)

b. Unsolder wire from circuit breaker A5CB1 connected to "230V" terminal of bias transformer A3T2 and solder it instead to "208V" terminal of

transformer (see Figure 2-2B). Leave wire from fan B2 (not used in 62599) soldered to “230V” terminal.

c.Re-install RFI assembly by reversing pro- cedure of Step (a).

d.Unsolder wire connected to terminal 5 of power transformer T1 (see Figure 7-4)and solder it instead to terminal 4 of transformer (see Figure 2-3 B).

2-20 To convert Model 6260B or 6269B to operation from a 208Vac source, taps on the power and bias transformers must be changed as follows:

a. Perform Steps (a) through (c) of Paragraph

2-18.

b. Unsolder wire connected to to "230V” terminal
