♦Disconnect the thyristors....
Too much compound between module and heat sink will give bad thermal
conduction and cause risk overheating the thyristors.
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.
♦Disconnect the electrical connection the thyristors.
♦Disconnect all cable from the terminals.SKKT172 MCC132.SKKT330 MCC225.
♦Clean the contact surface the heat sink and modules with Ethanol...
♦Discharge the tools and yourselfby touching earth.MCC162 3,0 5,0 2
SKKT210.
♦Connect the voltage and the other cable...Step step..
♦Mount the new thyristors (Use the torque the table).
