Step 2 Remove 1 screw from the Switching Regulator IC
(IC5701).
Step 3 Remove the Switching Regulator IC (IC5701) from the
Heatsink Ext A.
Caution: Avoid touching Heatsink Ext A due to its high
temperature after prolonged use. Touching it may lead to
injuries.
Note Refer to the diagrams of SMPS P.C.B. (Item 18.4) for
location of the part.
8.10.2. Assembly of Switching Regulator
IC (IC5701)
Step 1 Apply grease to the Heatsink Ext A.
Step 2 Mount the Switching Regulator IC (IC5701) to the
SMPS P.C.B..
Caution: Ensure pins of the Switching Regulator IC
(IC5701) are properly seated and soldered on SMPS P.C.B..
Step 3 Fix and screw the Switching Regulator IC (IC5701) to
the Heatsink Ext A.
Caution: Ensure the Switching Regulator IC (IC5701) is
tightly screwed to the Heatsink Ext A.
Step 4 Solder pins of the Switch Regulator IC (IC5701) on the
solder side of SMPS P.C.B..
