PRECAUTIONS

PLEASE READ CAREFULLY BEFORE PROCEEDING

* Please keep this manual in a safe place for future reference.

WARNING

Always follow the basic precautions listed below to avoid the possibility of serious injury or even death from electrical
shock, short-circuiting, damages, fire or other hazards. These precautions include, but are not limited to, the following:
•Only use the voltage specified as correct for the device. The required voltage
is printed on the name plate of the device.
• Do not place the power cord near heat sources such as heaters or radiators,
and do not excessively bend or otherwise damage the cord, place heavy
objects on it, or place it in a position where anyone could walk on, trip over,
or roll anything over it.
•Do not open the device or attempt to disassemble the internal parts or modify
them in any way. The device contains no user-serviceable parts. If it should
appear to be malfunctioning, discontinue use immediately and have it
inspected by qualified Yamaha service personnel.
• Do not expose the device to rain, use it near water or in damp or wet
conditions, or place containers on it containing liquids which might spill into
any openings.
• Never insert or remove an electric plug with wet hands.
•If the power cord or plug becomes frayed or damaged, or if there is a sudden
loss of sound during use of the device, or if any unusual smells or smoke
should appear to be caused by it, immediately turn off the power switch,
disconnect the electric plug from the outlet, and have the device inspected by
qualified Yamaha service personnel.
•If this device should be dropped or damaged, immediately turn off the power
switch, disconnect the electric plug from the outlet, and have the device
inspected by qualified Yamaha service personnel.

CAUTION

Always follow the basic precautions listed below to avoid the possibility of physical injury to you or others, or damage
to the device or other property. These precautions include, but are not limited to, the following:
•Remove the electric plug from the outlet when the device is not to be used for
extended periods of time, or during electrical storms.
•When removing the electric plug from the device or an outlet, always hold the
plug itself and not the cord. Pulling by the cord can damage it.
•Turn the unit ON or OFF using only the front-panel POWER switch. Turning
the unit ON or OFF by plugging or unplugging the power cord, using a switch
on a power tap, a breaker switch, or similar external means can result in
damage.
• Do not turn the POWER switch OFF and ON in rapid succession. Doing so
can result in excessive voltages that can cause damage. Wait at least 5
seconds before turning the POWER switch ON after it has been turned OFF.
• When transporting or moving the device, always use two or more people.
• Before moving the device, remove all connected cables.
• Do not expose the device to excessive dust or vibrations, or extreme cold or
heat (such as in direct sunlight, near a heater, or in a car during the day) to
prevent the possibility of panel disfiguration or damage to the internal
components.
• Do not place the device in an unstable position where it might accidentally
fall over.
•Do not block the vents. This device has ventilation holes at the front and rear
to prevent the internal temperature from rising too high. In particular, do not
place the device on its side or upside down, or place it in any poorly-
ventilated location, such as a bookcase or closet.
• Do not place the device against a wall or other devices since this can cause
inadequate air circulation, and possibly result in the device overheating.
Make sure there is adequate space between the device and any surrounding
wall or other devices: at least, 15cm behind and 15cm above.
•Do not use the device in the vicinity of a TV, radio, stereo equipment, mobile
phone, or other electric devices. Otherwise, the device, TV, or radio may
generate noise.
• Before connecting the device to other devices, turn off the power for all
devices. Before turning the power on or off for all devices, set all volume
levels to minimum.
• Be sure to connect to a properly grounded power source. A ground screw
terminal is provided on the rear panel for safely grounding the device and
preventing electrical shock.
• Do not insert your fingers or hand in any gaps or openings on the device
(vents etc.).
•Avoid inserting or dropping foreign objects (paper, plastic, metal, etc.) into
any gaps or openings on the device (vents etc.) If this happens, turn off the
power immediately and unplug the power cord from the AC outlet. Then have
the device inspected by qualified Yamaha service personnel.
•Do not rest your weight on the device or place heavy objects on it, and avoid
use excessive force on the buttons, switches or connectors.
Use the cable supplied with the PM5000 console to connect the PW5000
to the PM5000. When parallel-connecting two PW5000 units use the
optional PSL5000 Power Supply Link Cable to connect the second
PW5000 to the main PW5000 unit.
This power supply unit cannot be used in place of the PW4000 for the
PM4000 and PM3500 series mixing consoles, or in place of the PW1D for
the PM1D digital mixing console. The same connectors are used, but with
different pin assignments and voltages.
Yamaha cannot be held responsible for damage caused by improper use or modifications to the device, or data that is lost or destroyed.
Always turn the power off when the device is not in use.
The performance of components with moving contacts, such as switches, and
connectors, deteriorates over time. Consult qualified Yamaha service personnel
about replacing defective components.
