Notes:

The illustration above is based on the smaller
400V Three Phase frame size model (to
3.7kW). The terminal layout for larger 5.5kW
and 7.5kW frame sizes is similar.
The order of the three motor phases
determines the direction the motor turns.
The order of the three power phases is
unimportant.

Important:

Use screened cable between the Inverter and
M o t o r. To m i n i m i s e e l e c t r o m a g n e t i c

grounded.

specification.

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.
