Before commencing, confirm that the
Inverter and all cables are completely
isolated from the power supply, have
been isolated for at least 5 minutes and
that the motor is not turning.
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.
