Note: While the POWERTAP is capable of sustaining these vertical and levered tensions, the intimate contact

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.
