OPERATION
1. Before inserting the output plug,
switch all three switches (G) to
OFF. Then switch the converter
ON, using the ON/OFF switch (A)
on the front panel.
In this condition the lamp (B) will
illuminate.
Check to ensure the ammeter (C) is
set to zero. If necessary, adjust
using the small adjustment screw
located at the bottom centre of
the ammeter so that it reads zero.
2. Switch OFF the converter and
connect the plug from the
motor to the output socket (E).
3. Using the three switches (G), set
the output so that it is equivalent
to the HP of the motor to be
driven. This value should be found on the motor data plate.
The chart below shows the switch settings for the required outputs.
4. With the switches set, and the output plugged in, switch ON the converter
and proceed to start the motor/machine. Note that indicator lamp (F) will
illuminate when the switches (G) are set.
DO NOT ADJUST THE SWITCHES (G) WHEN THE PHASE CONVERTER IS SWITCHED
ON.
