●To reduce the risk of electric shock, do not remove the cover of this device. There are no user
serviceable parts inside - all repairs should be handled by a qualied technician.
●To reduce the risk of electrical shock, do not expose the voltage stabilzer to rain, moisture or
liquids. This unit is only suitable for indoor applications in dry rooms.
●Operate this voltage regulator only with dry clothes and dry hands.
●To reduce the risk of electrical shock, check if the power cable is properly inserted.
●Do not cover or enclose the ventilation openings and the ventilator of this voltage regulator.
Allow or the free ow of air for cooling.
●Do not overload this voltage regulator beyond its maximum capacity adjusted for the input
voltage level - for estimating the Load Capacity Input Voltage Factor, refer to the power capacity
guide chart.
●Do not attempt to change internal wiring of this voltage regulator.
●Avoid strong shaking, vibrations, and tipping over this voltage regulator.

3. Load Capacity Input Voltage Factor
The acceptable AC input range for the VRG series is between 140V and 270V. Inside this range the
VRG is able to stabilize the output power to 230V +/- 5% to provide a stabilized pure sine AC power.
Note that when the input voltage drops significantly the VRG must draw more current to provide
the voltage boost to keep the 230V output, this results in reduced power capacity as low as 50%
of the rated maximum. When voltages in these lower ranges are expected then it is necessary to
size your VRG larger to be able to meet the capacity demands of your attached equipment.
