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.

Emergency stop
CAUTION
!
Provide a safet
y
backup such as an emer
g
enc
y
brake which will prevent the
machine and equipment from hazardous conditions if the inverter fails.

)
Maintenance, inspection and parts replacement
CAUTION
!
Do not carry out a megger (insulation resistance) test on the control circuit of the
inverter.

)
Disposing of the inverter
CAUTION
!
Treat as industrial waste.

General instructions
Man
y
of the dia
g
rams and drawin
g
s in this instruction manual show the inverter
without a cover, or partiall
y
open. Never operate the inverter like this. Alwa
y
s
replace the cover and follow this instruction manual when operating the inverter.
