Failure to do so is a fire and electrical shock hazard. • Do not try to modify the power supply unit. This could be 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. • Turn off all audio devices and speakers when connecting to the power supply unit. Refer to the owner’s manual for each device. Use the correct cables and connect as specified. • 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 performance of some equipment. • Do not place heavy objects on the power cord. A damaged 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. • The power supply unit operating temperature is between 5˚C and 35˚C (41˚F and 95˚F). • 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 supply 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 circuits that may cause interference on radios and televisions placed close to it. If interference does occur, relocate the affected equipment. • 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. 3  ■Front panel 1 2 POWER OPERATION MONITOR +48V +12V +15V –15V POWER SUPPLY NORMAL ON/ OFF ■Rear panel 5 DC PARALLEL INPUT CONNECT 4 DC OUTPUT CONNECT PIN 2 +15V 4.2A PIN 5 –15V 4.2A PIN 6 +12V 4.1A PIN 9 +48V 0.2A DISCONNECT DISCONNECT 3 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 POWER ON/OFF 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 (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. E DC PARALLEL INPUT connector This connector allows two PW3000M units to be connected 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.
