6.Remove input power to the Power Wave 455M. If any of the voltages are low or not present, perform the Input Contactor Test. If that checks out, the Input Board may by faulty.

7.Reconnect lead X4 to the main input contac- tor CR1 coil terminal.

8.Carefully apply the correct input voltage to the Power Wave 455M.

WARNING

ELECTRIC SHOCK can kill.

High voltage is present when input power is applied to the machine.

9.Turn on the Power Wave 455M. Check for the presence of 24 VAC from lead X4 to lead 601. See Figure F. 9. If the voltage is not present, perform the Auxiliary

Transformer #1 Test.

9.This 24 VAC is the coil voltage for main input contactor CR1. It will normally be present approximately 12 seconds after input line switch (SW1) is activated.

10.When the test is completed, remove input power from the Power Wave 455M.

11.Install the case top and reconnect cover using the 3/8” nut driver.
