SKKT27.
Too much compound between module and heat sink will give bad thermal
conduction and cause risk overheating the thyristors.MCC95 3,0 3,0 1

♦Disconnect the thyristors.
♦Disconnect the electrical connection the thyristors.SKKT92 MCC26.SKKT172 MCC132..
♦Connect the voltage and the other cable....
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..
♦Remove the front cover..
♦Mount the new thyristors (Use the torque the table).
