A wide variety of optional units, DIM module, CF cards, manufactured by Pro-face and commercial

3.3.1 Main Memory Installation
„ PS-3650A
(1) Turn OFF the power switch of the PS-A and remove the power cable. Place the PS-A on a flat, level sur-
face facing the display face downwards.
(2) Unscrew the screws (2) as you see on the following figure, then remove the cooling fan.
Be sure to confirm that power is not supplied to the PS-A unit before installing or removing
any optional units, DIM module, CF cards, or Expansion boards (PCI boards). Failure to do
so can result in an electric shock.
• If the PS-A unit is in the Soft OFF Status, power is supplied to a part of circuits
even when no screen is displayed. Be sure to confirm that a power cable is not
connected before installing or removing peripheral equipment.
• Use a screwdriver to loosen or tighten the screws. Be sure not to tighten screws
too tightly, since it may damage the unit.
• When removing or replacing screws, be careful that they do not fall inside the PS-
A unit’s chassis.
• When installing the PS-A unit, or when attaching an optional item to the PS-A
unit, do not hold the PS-A unit’s rear-face fan cover while performing the work.
Doing so may damage the fan cover or cause the cover to fall off.
