2. Installing the P.C. Board
(1) Apply thermal grease to the back (heat sink contacting side) of devices Q201, Q650, DB01, DB02 and
aluminum plate.( Q300 and Q400 are not necessary to be applied thermal grease.)
(2) Reuse the aluminum plate.
(3) Reuse the insulating sheet. When a small amount of thermal grease is applied to the back of the insulating
sheet, it adheres temporarily to the heat sink, which makes it easy to attach the insulating sheet.
(4) Insert the P.C. board, align the holes of the insulating sheets, semiconductor devices, and heat sinks, and
then secure them with screws.
(5) Connect the lead wires according to the wiring diagram stuck on the backside of the panel.
Apply thermal grease to the back
(heat sink contacting side) of
Q201,Q650, DB01, and DB02.
