Yamaha PW3000M Manual Do Utilizador

 

■

 

• Connect the power supply power cord only to an AC 

outlet of the type stated in this 

 

or as 

marked on the power supply unit. Failure to do so is a 
fire and electrical shock hazard.

• Do not locate the power supply unit in a place subject 

to excessive heat or in direct sunlight. This could be a 
fire hazard.

• Do not place the power supply unit in a place subject 

to excessive humidity or dust. This could be a fire and 
electrical shock hazard.

• Do not plug several devices into the same AC outlet. 

This may overload the AC outlet, and could be a fire 
and electrical shock hazard. It may also affect the per-
formance of some equipment.

• Do not place heavy objects on the power cord. A dam-

aged power cord is a potential fire and electrical shock 
hazard.

• If the power cord is damaged (i.e., cut or a bare wire is 

exposed), ask your dealer for a replacement. Using the 
power supply unit in this condition is a fire and shock 
hazard.

• Hold the power cord plug when disconnecting from 

an AC outlet. Never pull the cord. Damaging the 
power cord in this way is a potential fire and electrical 
shock hazard. 

• Do not place small metal objects on top of the power 

supply unit. Metal objects inside the power supply 
unit are a fire and electrical shock hazard. 

• Do not block the power supply unit ventilation slots. 

The power supply unit has ventilation slots at the 
front to prevent the internal temperature from rising. 
Blocked ventilation slots are a fire hazard. 

• Leave a reasonable amount of free-air space around 

the power supply unit.

• If the power supply unit is to be rack mounted, leave 

at least 10 cm free above the top panel and behind the 
rear panel. When the power supply unit is in use, 
remove the rear of the rack, or open its ventilation 
slots to prevent overheating, which could be a fire 
hazard. 

• Do not try to modify the power supply unit. This 

could be a fire and electrical shock hazard.

• The power supply unit operating temperature is 

between 5˚C and 35˚C (41˚F and 95˚F).

• Turn off all audio devices and speakers when connect-

ing to the power supply unit. Refer to the owner’s 
manual for each device. Use the correct cables and 
connect as specified.

• If you notice any abnormality—such as smoke, odor, 

or noise—turn off the power supply unit immediately. 
Remove the power cord from the AC outlet. Confirm 
that the abnormality is no longer present. Consult 
your dealer for repair. Using the power supply unit in 
this condition is a fire and shock hazard.

• If a foreign object or water gets inside the power sup-

ply unit, turn it off immediately. Remove the power 
cord from the AC outlet. Consult your dealer for 
repair. Using the power supply unit in this condition 
is a fire and electrical shock hazard.

• If you plan not to use the power supply unit for a long 

period of time, remove the power cord from the AC 
outlet. Leaving the power supply unit connected is a 
fire hazard.

• Do not use benzene, thinner, cleaning detergent, or a 

chemical cloth to clean the power supply unit. Use 
only a soft, dry cloth.

• The power supply unit uses high-frequency digital cir-

cuits that may cause interference on radios and televi-
sions placed close to it. If interference does occur, 
relocate the affected equipment.
