Note: While the POWERTAP is capable of sustaining these vertical and levered tensions, the intimate contact Note: between POWERTAP and heat sink may be lost. This could lead to thermal runaway. The use of very Note: flexible leads is recommended for the anode connections. Use of thermal grease is highly recommended.
MOUNTING PROCEDURE
The POWERTAP package requires special mounting considerations because of the long longitudinal axis of the copper heat sink. It is important to follow the proper tightening sequence to avoid warping the heat sink, which can reduce thermal contact between the POWERTAP and heat sink.
STEP 1: Locate the POWERTAP on the heat sink and start mounting bolts into the threads by hand (2 or 3 turns).

STEP 2: Finger tighten the center bolt. The bolt may catch on the threads of the heat sink so it is important to make sure the face of the bolt or washer is in contact with the surface of the POWERTAP. STEP 3: Tighten each of the end bolts between 5 to 10 in-lb.
