Operation
The VTCi320 Voltage Converter is designed for simple operation. It is intended to operate fully
unattended and will attempt to recover from any fault, including Over-Temperature, Low Input
Voltage, Input Power Failure and Overload.
TO OPERATE
1. Press the Power Button on the unit’s front panel. It will start glowing.
2. The voltage converter will go through its startup sequence. All 6 microprocessor-
controlled LEDs flash red and then green. When the Power Button starts glowing, the
sequence is complete.
3. The VTCi320 will automatically supply the load with the voltage indicated on its label for
as long as the load is connected.
4. The Indicator LEDs can be used to determine the amount of current being drawn by the
load. See the diagram below.

TO END OPERATION
1. Press the Power Button on the unit’s front panel.
2. The voltage converter will beep and the LED indicators will stop glowing.
3. When all the LEDs are dim, the unit is safe to disconnect from the load and power source.
4. The unit can now be safely serviced or put into storage.
TO INSTALL
1. Connect the Voltage Converter to the load before con-
necting the input power.
2. Connect the Power Supply to the input power. The IP
LED should illuminate indicating it is receiving power.
