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

When installing the optional units, refer to each unit’s “Installation Guide”.
3.2.1 Main Memory Installation
„ PS-3650A Series
(1) Turn OFF the power switch of the PS-A unit and remove the power cable. Place the PS-A unit on a flat,
level surface facing the display face downwards.
(2) Unscrew the screws (2) as you see on the following figure, and remove the Fan Unit.
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, Expansion boards (PCI boards), or PCMCIA
(PC Cards). 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 Unit while performing the work.
Doing so may damage the fan cover or cause the cover to fall off.
