♦Discharge the tools and yourselfby touching earth.
♦Mount the new thyristors (Use the torque the table).
♦Disconnect the voltage from terminals 1L1, 3L2, and 5L3 (main supply).
♦Disconnect the thyristors.
♦Disconnect the electrical connection the thyristors.SKKT330 MCC225..
♦Remove the front cover..
♦Connect the voltage and the other cable.
♦Clean the contact surface the heat sink and modules with Ethanol.Step step..
Too much compound between module and heat sink will give bad thermal
conduction and cause risk overheating the thyristors.MCC312 3,0 9,0 3

♦Mount the front cover.
Use lint-free cloth (paper linen cloth)
♦A very thin layer ofheat transfer compound shall put the contact surfaces of
