Technical Manual
Installation of the new Power PCB (121-10-02, version G or later)
a) Install the new Power supply PCB as follows. Connect the Power supply PCB to the CPU
PCB. Attach the Power supply PCB to its position with the eight attachment screws but do
NOT tighten the attachment screws yet (1).
NOTE If the column motor cable was not attached with a PCB holder bush to the old Power
supply PCB
(5) , there must be a ninth attachment screw in that location.
b) Make sure that the metal clips are not between the heat sink and column, but they are located
above and below the heat sink (2). Make sure that the cables are not squeezed between the
heat sink and column.
c) Before tightening the attachment screws push first the Power supply PCB lower edge towards
the right side of the column so that the heat sink touches the column (3). Tighten the lowest
left attachment screw (1a).
d) Then push the Power supply PCB upper edge towards the right side of the column so that the
heat sink touches the column (4). Tighten the uppermost middle attachment screw (1b).
Firmly tighten the attachment screws of both the Power supply PCB and the CPU PCB.
e) Connect all the cables to the Power supply PCB.
f) If the column motor cable was attached with a PCB holder bush to the old Power supply PCB,
use the same bush and attachment screw when attaching the column motor cable to the new
PCB (5).
g) Replace the removed parts.
