TROUBLESHOOTING & REPAIR

REPLACEMENT PROCEDURE

1.Apply a thin coating of Penetrox A-13 Electrical Joint Compound to the mating sur- faces of the output power board and the heat sink. Make sure the surfaces are clean. Do not allow the compound to get into the threaded holes or on the screw threads.

CAUTION

Be sure to follow the recommended static-free methods for handling printed circuit boards. Failure to do so can result in permanent damage to the equipment.

2.Mount the output power board to the heat sink and pre-torque the four socket head screws to 25 inch-pounds.

3.Finish tightening the four screws to 40-48 inch-pounds.

4.Replace the four phillips head screws previ- ously removed.

5.Replace leads X20 and X40.

6.Replace plugs J30, J31, J32, J33, and J34.

7.Replace leads X4 and X2, then torque to 75 IN. LBS.

8.Replace lead B21 and torque it to 75 IN. LBS.

9.Clear and secure all leads and replace the wraparound cover.
