Wiring
CAUTION
!
Do not fit capacitive equipment such as a power factor correction capacitor,
noise filter or surge suppressor to the output of the inverter.
!
The connection orientation of the output cables U, V, W to the motor will affect
the direction of rotation of the motor.

Operation
WARNING
!
When you have chosen the retry function, stay away from the equipment as it
will restart suddenly after an alarm stop.
!
The load used should be a three-phase induction motor only. Connection of any
other electrical equipment to the inverter output may damage the equipment.
!
Do not modify the equipment.
CAUTION
!
The electronic overcurrent protection does not guarantee protection of the motor
from overheating.
!
Do not use a ma
g
netic contactor on the inverter input for frequent
starting/stopping of the inverter.
!
Use a noise filter to reduce the effect of electromagnetic interference. Otherwise
nearby electronic equipment may be affected.
!
Take measures to suppress harmonics. Otherwise power harmonics from the
inverter may heat/damage the power capacitor and generator.
!
When parameter clear or all clear is performed, each parameter returns to the
factory setting. Re-set the required parameters before starting operation.
!
The inverter can be easil
y
set for hi
g
h-speed operation. Before chan
g
in
g
its
setting, fully examine the performances of the motor and machine.
!
In addition to the inverter's holdin
g
function, install a holdin
g
device to ensure
safety.
!
Before runnin
g
an inverter which had been stored for a lon
g
period, alwa
y
s
perform inspection and test operation.
