Yamaha PW3000MA Manual Do Utilizador

 

■

 

■

 

The PW3000MA power supply should be installed in a 
well ventilated location.
In particular, the front and rear panels must not be 
blocked, since the ventilation path passes through them.

 

A

 

 switch

 

After connections to the mixer have been completed, 
turn this switch on to supply power to the mixer.

 

B

 

Operation monitor

 

These LEDs indicate the status of the four types of 
power that are being supplied to the mixer. Normally 
(i.e., when no malfunction has occurred), the green 
LEDs (NORMAL) will light. If a malfunction occurs, 
the LED for that section of the power supply will go 
dark. Turn the power off and wait for a time before 
turning the power on again. If the same LED(s) are 
dark, contact a Yamaha service center.

 

C

 

GND terminals

 

This is the grounding screw terminal. If hum or noise 
occurs, ground (earth) the unit via this jack, or try 
connecting it to the chassis of the other device.

 

D

 

 connector

 

Connect this connector to the mixer to supply power 
to it.

 

E

 

 connector

 

This connector allows two PW3000MA units to be 
connected in parallel. As shown in the following dia-
gram, use the included parallel connection cable to 
make connections. In this case, the two PW3000MA 
units will each supply 50% of the power in normal 
operation. Even in the unlikely event that one of the 
PW3000MA units failed, the other PW3000MA will 
supply 100% of the power, ensuring an uninterrupted 
power supply.
