V
¨
In case of input voltage unbalance, install AC reactor. Power Factor capacitors and
generators may become overheated and damaged due to potential high frequency
noise transmitted from inverter.
¨
Use an insulation-rectified motor or take measures to suppress the micro surge voltage
when driving 400V class motor with inverter. A micro surge voltage attributable to
wiring constant is generated at motor terminals, and may deteriorate insulation and
damage motor.
¨
Before operating unit and prior to user programming, reset user parameters to default
settings.
¨
Inverter can easily be set to high-speed operations, Verify capability of motor or
machinery prior to operating unit.
¨
Stopping torque is not produced when using the DC-Break function. Install separate
equipment when stopping torque is needed.
(5) Fault prevention precautions
¨
Provide a safety backup such as an emergency brake which will prevent the machine
and equipment from hazardous conditions if the inverter fails.
(6) Maintenance, inspection and parts replacement
¨
Do not conduct a megger (insulation resistance) test on the control circuit of the
inverter.
¨
Refer to Chapter 8 for periodic inspection (parts replacement).
(7) Disposal
¨
Handle the inverter as an industrial waste when disposing of it.
(8) General instructions
Many of the diagrams and drawings in this instruction manual show the inverter without a circuit
breaker, a cover or partially open. Never run the inverter like this. Always place the cover with
circuit breakers and follow this instruction manual when operating the inverter.
