Optional Plug-in Board Installation
A variety of optional Plug-in boards (page 19) sold
separately let you expand the voice library of your
instrument.
The following types of Plug-in boards can be used with
your instrument.
• PLG150-AN
• PLG150-PF
• PLG150-VL
• PLG150-DX
• PLG150-DR
• PLG150-PC
• PLG100-XG
Installation Precautions
Before installing the optional hardware, make sure you
have a Philips screwdriver.
•Before beginning installation, switch off the power to
the MOTIF-RACK and connected peripherals, and
unplug them from the power outlet. Then remove all
cables connecting the MOTIF-RACK to other devices.
(Leaving the power cord connected while working can
result in electric shock. Leaving other cables connected
can interfere with work.)
•Be careful not to drop any screws inside the instrument
during installation (this can be prevented by keeping
the optional units and cover away from the instrument
while attaching). If this does happen, be sure to remove
the screw(s) from inside the unit before turning the
power on. Loose screws inside the instrument can
cause improper operation or serious damage. If you are
unable to retrieve a dropped screw, consult your
Yamaha dealer for advice.
•Install the optional units carefully as described in the
procedure below. Improper installation can cause shorts
which may result in irreparable damage and pose a fire
hazard.
•Do not disassemble, modify, or apply excessive force to
board areas and connectors on optional units. Bending
or tampering with boards and connectors may lead to
electric shock, fire, or equipment failures.
•It is recommended that you wear gloves to protect your
hands from metallic projections on optional units and
other components. Touching leads or connectors with
bare hands may cause finger cuts, and may also result in
poor electrical contact or electrostatic damage.
•Handle the optional units with care. Dropping or
subjecting them to any kind of shock may cause damage
or result in a malfunction.
•Be careful of static electricity. Static electricity
discharge can damage the IC chips on the Plug-in board.
Before you handle the optional Plug-in board, to reduce
the possibility of static electricity, touch the metal parts
other than the painted area or a ground wire on the
devices that are grounded.
•Do not touch the exposed metal parts in the circuit
board. Touching these parts may result in a faulty
contact.
•When moving a cable, be careful not to let it catch on
the circuit Plug-in board. Forcing the cable in anyway
may cut the cable, cause damage, or result in a
malfunction.
•Be careful not to misplace any of the screws since all of
them are used.
•Do not use any screws other than what are installed on
the instrument.
