♦Mount the electrical connection the thyristors.
♦Disconnect the voltage from terminals 1L1, 3L2, and 5L3 (main supply).
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..
♦Connect the voltage and the other cable.
♦Disconnect the thyristors.
♦Mount the new thyristors (Use the torque the table)..SKKT172 MCC132..MCC95 3,0 3,0 1
