of these wire connections is not important.
5. Remove the three wires that go to the
motor. The wires are marked 1, 2 and 3.
TeCH Tip: Always note the order these
wires are connected. This is important
because if any two of the three wires are
reversed, the motor rotation will be opposite
what it should be.
nOTe: Do not attach a power supply wire
to any output terminal, because immediate
damage will occur upon applying voltage
and the inverter would be destroyed (No
warranty will apply).
