5. Operation of the AVR
a. Connect the Electrical Appliances to Regulator
• Make sure all appliances are turned "OFF", and put power switch of AVR to “OFF” position.
• For model from 500VA to 2000VA, plug the AC mains cord of the appliances into the output socket of AVR,
ensuring that the total starting power needed does not exceed the rated maximum output power of the AVR.
b. Connect Regulator to Electrical Mains
•
For model from 500VA to 2000VA, just plug the AC mains cord to wall mains socket.
c. Switch on the regulator
• Put the
POWER SWITCH
to
"ON"
position, the
LED DISPLAY
will light on, the
DELAYING LED
will light and
blink . At the same time, the digital display will show the elapsing delay time. Generally delay time is set at 6
seconds.
• When the delay is finished, the
DELAYING LED
lights off, and the
LED DISPLAY
will show output voltage
supplying to appliances connected to the AVR.
• Switch "ON" the appliances one by one.
In Case of Power Failure:
• Switch "OFF" the regulator and all the appliances.
• Repeat above steps when power is restored.
d. Display of Input Voltage and Output Voltage
• The input voltage and output voltage will show in the LED DISPLAY after the AVR is switched on.
e. Overheat Protection
• This AVR is equipped with a unique TEMPERATURE PROTECTION CIRCUIT designed to protect the
transformer, giving you longer and satisfactory use of the AVR.
• If the internal temperature of the windings of transformer reaches the limit or above,the output will be cut
“OFF” automatically, and the OUTPUT LED DISPLAY will show “C”.
