.Step step.
Too much compound between module and heat sink will give bad thermal
conduction and cause risk overheating the thyristors.SKKT172 MCC132..
♦Disconnect all cable from the terminals.SKKT92 MCC26.

♦Discharge the tools and yourselfby touching earth.....
Use lint-free cloth (paper linen cloth)
♦A very thin layer ofheat transfer compound shall put the contact surfaces of
the modules with lint-free cloth..
♦Mount the front cover.MCC95 3,0 3,0 1
