Note: while the POWERTAP is capable of sustaining these vertical and levered tensions, the intimate contact
between POWERTAP and heat may be lost .This could lead to thermal runaway. The use of very
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
