REMOVAL PROCEDURE

1.Remove input power to the V450-PRO.

2.Using the 3/8” nut driver, remove the case top, input access panel and sides.

3.Perform the Capacitor Discharge Procedure.

4.Locate and remove the RTV sealant from the input rectifier connection terminals. See Figure F.17.

5.Label and, using the Phillips head screwdriver, carefully remove the five leads from the input rectifier terminals. Note placement for reassembly. See Figure F.17.

6.Using the 3/16” allen wrench, remove the two mounting screws and washers from the rectifier module.

7.Carefully remove the input rectifier module.

REPLACEMENT PROCEDURE

1.Clean heat sink surfaces.

2.Apply an even coating of joint compound (Penetrox A-13) to both the heat sink and mod- ule mounting surfaces. The joint compound should be 0.002 - 0.005 in. thick per surface.

3.Mount the module to the heat sink and evenly torque the mounting screws (with washers) to 44 in/lbs.

4.Assemble the leads to the correct module ter- minals and torque to 26 in/lbs. See Figure F.17.

5.Apply RTV sealant to the rectifier connection terminals.

6.Install the case top, sides, and input access panel using the 3/8” nut driver.
