Yamaha PW3000M Manual Do Utilizador

 

■

 

■

 

The PW3000M 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 M3000 have been completed, 
turn this switch on to supply power to the M3000.

 

B

 

Operation monitor

 

Four LEDs indicate the status of the power that is 
being supplied to the M3000. Normally (i.e., when no 
malfunction has occurred), the green LEDs (NOR-
MAL) 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 M3000 to supply power 
to it.

 

E

 

 connector

 

This connector allows two PW3000M units to be con-
nected in parallel. As shown in the following diagram, 
use the included parallel connection cable to make 
connections. In this case, the two PW3000M units will 
each supply 50% of the power in normal operation. 
Even in the unlikely event that one of the PW3000M 
units failed, the other PW3000M will supply 100% of 
the power, ensuring an uninterrupted power supply.
