Notes:
The illustration on the left is based on the
smaller 230V Single Phase frame size model
(to 0.75kW). The terminal layout for larger
frame sizes is similar.
The order of the three motor phases
determines the direction the motor turns.
Use screened cable between the Inverter and
Motor. To minimise electromagnetic
interference, ensure the cable screen is
grounded.
