7. Carefully apply the correct input voltage to the
POWER WAVE 355/405 and check for the cor-
rect secondary voltages per table F.5. Make
sure the reconnect jumper lead and switch are
configured correctly for the input voltage
being applied. Make sure circuit breaker
(CB3) is functioning properly.
NOTE: The secondary voltages will vary if the
input line voltage varies.
8. If the correct secondary voltages are present,
the auxiliary transformer is functioning proper-
ly. If any of the secondary voltages are miss-
ing or low, check to make certain the primary
is configured correctly for the input voltage
applied. See Wiring Diagram.
High voltage is present at primary of
Auxiliary Transformer.
9. If the correct input voltage is applied to the
primary, and the secondary voltage(s) are not
correct, the auxiliary transformer may be
faulty.
10. Remove the input power to the POWER WAVE
355/405.
11. Install the case wraparound cover using a
5/16” nut driver.
