9.2 SCR INSTALLATION PROCEDURE

• Clean both heat sink and SCR surfaces.
• Apply a thin layer of joint compound (Noalox) to both SCR surfaces.
• Observe correct SCR polarity.
• Install SCR so that roll pins engage dimples on both sides of the SCR.
• Tighten clamp bolts evenly until finger-tight.
• Tighten each bolt according to table below (based on number of spring bars and size of
bars).
Note: SMALL clamps are 10.5cm(4.25inches) and LARGE clamps are 12.5cm(5inches)
