Set POWER switch at the OFF position. Connect the grid to the INPUT pole (behind the machine).
               - 110V pole for the 110V grid.
               - 220V pole for the 220V grid.
               - 380V pole for the 380V grid.

 Set the POWER switch at the ON position.
 Let the machine working steadily for some minutes, and then turn on the necessary electronic – electric equipment.
              - The plug on the lower side of the machine is only for the use of the LOW      VOLTAGE equipment. The HIGH VOLTAGE equipment needs to use OUTPUT pole behind the machine.
 To TURN OFF the stabilizer machine, it needs to set the POWER switch at the OFF position.

1. Never use the regulator in an over load condition or never exceed the current rating and the KVA rating are specified under the condition of the supply voltages deviation. The current rating and the KVA rating are specified under the condition of the 10% supply voltage deviation.

2. The available KVA will be reduced in proportion to supply voltage:
   - When using the regulator in areas where line voltage is extremely low or high.
   - When input voltage: 220V, output voltage: 110V or on the contrary.
   - When the output terminals for both 110V and 220V are employed at the same time.
   Should be reduce the current equipments, or use the regulator whose the KVA rating is increased from 1.5 times to 2 times.

3. For the equipment started up by motor (Eg: water pump, air conditioner,..). You should be use the regulator whose KVA rating is increased minimum 2 times of the current rating and should be start the equipment in turn.

4. Take account of the voltage drop which occurs between the regulator and load. When connecting the output terminals to load, use cables of higher rating than the desired output current to avoid unnecessary voltage drop.

5. Do not place the regulator in humid environment, in dust, near the chemical.
