for wiring or periodic inspection. You may access the
charged inverter circuits and get an electric shock.
z Before starting wiring or inspection, switch off power,
check to make sure that the operation panel indicator is
off, wait for at least 10 minutes after the power supply has
been switched off, and check that there are no residual
voltage using a tester or the like. The capacitor is charged
with high voltage for some time after power off and it is
dangerous.
z This inverter must be earthed (grounded). Earthing
(grounding) must conform to the requirements of national
and local safety regulations and electrical code. (NEC
section 250, IEC 536 class 1 and other applicable
standards)

may get an electric shock or be injured.
z Perform setting dial and key operations with dry hands to
prevent an electric shock. Otherwise you may get an
electric shock.
z Do not subject the cables to scratches, excessive stress,
heavy loads or pinching. Otherwise, you may get an
electric shock.
z Do not change the cooling fan while power is on. It is
dangerous to change the cooling fan while power is on.
z Do not touch the printed circuit board with wet hands.
Otherwise, you may get an electric shock.
z When measuring the main circuit capacitor capacity, the
DC voltage is applied to the motor for 1s at powering off.
Never touch the motor terminal, etc. right after powering
off to prevent an electric shock.
2. Fire Prevention
CAUTION
z Install the inverter on a nonflammable wall without holes
(so that nobody can touch the inverter heatsink on the
rear side, etc.). Mounting it to or near combustible
material can cause a fire.
z If the inverter has become faulty, switch off the inverter
power. A continuous flow of large current could cause a
fire.
z When using a brake resistor, make up a sequence that will
turn off power when an alarm signal is output. Otherwise,
the brake resistor may excessively overheat due to
damage of the brake transistor and such, causing a fire.
z Do not connect a resistor directly to the DC terminals +
and -. This could cause a fire.
3.Injury Prevention
CAUTION
z
Apply only the voltage specified in the instruction manual
to each terminal. Otherwise, burst, damage, etc. may occur.
z Ensure that the cables are connected to the correct
terminals. Otherwise, burst, damage, etc. may occur.
z Always make sure that polarity is correct to prevent
damage, etc. Otherwise, burst, damage, etc. may occur.
z While power is on or for some time after power-off, do not
touch the inverter as they will be extremely hot. Doing so
can cause burns.
4. Additional Instructions

CAUTION
z Do not install a power factor correction capacitor or surge
suppressor/capacitor type filter on the inverter output
side. These devices on the inverter output side may be
overheated or burn out.
z The connection orientation of the output cables U, V, W to
the motor will affect the direction of rotation of the motor.
(3) Trial run
CAUTION
z Before starting operation, confirm and adjust the
parameters. A failure to do so may cause some machines
to make unexpected motions.
(4) Usage
WARNIN
z When you have chosen the retry function, stay away from
the equipment as it will restart suddenly after trip.
z Since pressing key may not stop output depending
on the function setting status, provide a circuit and switch
separately to make an emergency stop (power off,
mechanical brake operation for emergency stop, etc).
z Make sure that the start signal is off before resetting the
inverter alarm. A failure to do so may restart the motor
suddenly.
z 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.
z Do not modify the equipment.
z Do not perform parts removal which is not instructed in
this manual. Doing so may lead to fault or damage of the
product.
(5) Emergency stop
CAUTION
z Provide a safety backup such as an emergency brake
which will prevent the machine and equipment from
hazardous conditions if the inverter fails.
z When the breaker on the inverter input side trips, check
for the wiring fault (short circuit), damage to internal parts
of the inverter, etc. Identify the cause of the trip, then
remove the cause and power on the breaker.
z When any protective function is activated, take the
appropriate corrective action, then reset the inverter, and
resume operation.
(6) Maintenance, inspection and parts replacement
CAUTION
z Do not carry out a megger (insulation resistance) test on
the control circuit of the inverter. It will cause a failure.
(7) Disposal
CAUTION
z Treat as industrial waste.
General instruction
Many of the diagrams and drawings in this Installation
Guideline show the inverter without a cover, or partially
open. Never operate the inverter in this manner. Always
replace the cover and follow this Installation Guideline
when operating the inverter.
CAUTION
z
The electronic thermal relay function does not guarantee
protection of the motor from overheating. It is recommended
to install both an external thermal and PTC thermistor for
overheat protection.
z Do not use a magnetic contactor on the inverter input for
frequent starting/stopping of the inverter. Otherwise, the
life of the inverter decreases.
z Use a noise filter to reduce the effect of electromagnetic
interference. Otherwise nearby electronic equipment may
be affected.
z Take measures to suppress harmonics. Otherwise power
supply harmonics from the inverter may heat/damage the
power factor correction capacitor and generator.
z When a 400V class motor is inverter-driven, please use an
insulation-enhanced motor or measures taken to
suppress surge voltages. Surge voltages attributable to
the wiring constants may occur at the motor terminals,
deteriorating the insulation of the motor.
z When parameter clear or all parameter clear is performed,
reset the required parameters before starting operations.
Each parameter returns to the initial value.
z The inverter can be easily set for high-speed operation.
Before changing its setting, fully examine the
performances of the motor and machine.
z In addition to the inverter’s holding function, install a
holding device to ensure safety.
z Before running an inverter which had been stored for a
long period, always perform inspection and test
operation.
z For prevention of damage due to static electricity, touch
nearby metal before touching this product to eliminate
static electricity from your body.
