Yamaha MOTIF-RACK Manual Do Utilizador

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

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.
