2. Power and Motor Connections (Three Phase)
The supply must match the Inverter
specification.
The order of the three supply phases is not
important.
The order of the three motor phases
determines the initial direction the motor turns.
This can be reversed by physically swapping
any two motor phases. Or by changing the
Inverter parameters.
Use screened or armoured cable between the
Inverter and Motor. To minimise
electromagnetic interference, ensure the
cable screen is grounded.
Notes:
The illustration on the left is based on frame
size 1 (ratings to 1.5kW). The terminal layout
for frames 2-4 is similar.
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.
