TABLE F.7 – SECONDARY VOLTAGES
7. Carefully apply the correct input voltage to the
POWER WAVE 655/R.
ELECTRIC SHOCK can kill.
High voltage is present at primary of
the Auxiliary Transformer.
8. Check for the correct secondary voltages according
to Table F.7.
NOTE: The secondary voltages will vary proportionally
if the input line voltage varies from nominal.
9. If the correct secondary voltages are present, the
T1 auxiliary transformer is functioning properly. If
any of the secondary voltages are missing or low,
check to make certain the primary is configured
correctly for the input voltage applied. See the
Wiring Diagram.
10. If the correct input voltage is applied to the prima-
ry, and the secondary voltage(s) are not correct,
the T1 transformer may be faulty.
11. Replace any cables ties and insulation removed
earlier.
12. Replace the case sides and top.
