3.2.5 HDD Unit Installation

 PS-3650A Series

(1) Turn OFF the power switch of the PS-A and remove the power cable. Place the PS-A unit on a flat, level

surface facing the display face downwards.

(2) Unscrew the Expansion Board Cover's screws (2) and remove the Expansion Board Cover.

(3) Unscrew the Expansion Board Base's screws (4) and remove the Expansion Board Base.

Shock Danger! Be sure to unplug the PS-A unit from its power supply prior to installing the

HDD unit.

• Since the HDD unit and the PS-A unit’s circuit board are precision instruments that

have a low resistance to shocks, be sure they are neither hit by nor pressed strongly

against another object when installing the HDD.

• Even when the screen display of the monitor connected to the PS-A unit is blank, the

power might be distributed internally (for example, in the Standby state). Make sure

that the power supply of the PS-A unit is off when installing or removing the HDD unit.
