MOUNTING INSTRUCTIONS Following these installation instructions will result in a rectifier diode-to-heatsink contact thermal resistance of 0.08C/watt or less. 1. Be sure mounting surface is clean and flat within .001 inch/inch. 2. Mounting hole diameter should not exceed the outside diameter of the rectifier diode stud by more than 1/16 inch, and should be deburred. 3. Use Dow Cornings DC3, 4, 340 or 640 or GE G322L or equivalent, on mounting surfaces that come in contact with the heatsink. 4. Use only hardware furnished with each rectifier diode. 5. Tighten with a torque wrench, from nut side, to 300 Ib-in. 246
