7.Carefully apply the correct input voltage to the POWER WAVE 355M/405M and check for the correct 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.
WARNING
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 355M/405M.
11.Install the case wraparound cover using a 5/16” nut driver.
