This section is specifically about safety matters

Do not attempt to install, operate, maintain or inspect the inverter until you
have read through this Installation Guideline and appended documents
carefully and can use the equipment correctly. Do not use the inverter until
you have a full knowledge of the equipment, safety information and
instructions. In this Installation Guideline, the safety instruction levels are
classified into "WARNING" and "CAUTION".

WAR NI NG

CAUTION

The level may even lead to a serious consequence according

CAUTION

to conditions. Both instruction levels must be followed because these are
important to personal safety.

Incorrect handling may cause hazardous conditions,
resulting in death or severe injury.
Incorrect handling may cause hazardous conditions,
resulting in medium or slight injury, or may cause
only material damage.

1. Electric Shock Prevention

• While power is on or when the inverter is running, do not open the front
cover. Otherwise you may get an electric shock.

• Do not run the inverter with the front cover removed. Otherwise, you may
access the exposed high-voltage terminals or the charging part of the
circuitry and get an electric shock.

•

Even if power is off, do not remove the front cover except for wiring or periodic
inspection.You may access the charged inverter circuits and get an electric shock.

• Before wiring, inspection or switching EMC filter ON/OFF connector,
power must be switched OFF. To confirm that, LED indication of the
operation panel must be checked. (It must be OFF.) Any person who is
involved in wiring, inspection or switching EMC filter ON/OFF connector
shall 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.

• This inverter must be grounded. 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).
A neutral-point grounded power supply for 400V class inverter in
compliance with EN standard must be used.

• Any person who is involved in wiring or inspection of this equipment shall
be fully competent to do the work.

• The inverter must be installed before wiring. Otherwise you may get an
electric shock or be injured.

• Setting dial and key operations must be performed with dry hands to
prevent an electric shock. Otherwise you may get an electric shock.

• Do not subject the cables to scratches, excessive stress, heavy loads or
pinching. Otherwise you may get an electric shock.

• Do not replace the cooling fan while power is on. It is dangerous to replace
the cooling fan while power is on.

• Do not touch the printed circuit board with wet hands. You may get an
electric shock.

• When measuring the main circuit capacitor capacity (Pr. 259 Main circuit
capacitor life measuring = "1"), 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

• Inverter must be installed on a nonflammable wall without holes (so that
nobody touches the inverter heatsink on the rear side, etc.). Mounting it to
or near flammable material can cause a fire.

• If the inverter has become faulty, the inverter power must be switched
OFF. A continuous flow of large current could cause a fire.

• Do not connect a resistor directly to the DC terminals P/+ and N/-. Doing
so could cause a fire.

3. Injury Prevent ion

• The voltage applied to each terminal must be the ones specified in the
Instruction Manual. Otherwise burst, damage, etc. may occur.

• The cables must be connected to the correct terminals. Otherwise burst,
damage, etc. may occur.

• Polarity must be correct. Otherwise burst, damage, etc. may occur.

• While power is ON or for some time after power-OFF, do not touch the

inverter since the inverter will be extremely hot. Doing so can cause burns.

WARNING

CAUTION

CAUTION

4. Additional Instructions

Also the following points must be noted to prevent an accidental failure, injury,
electric shock, etc.

(1) Transportation and installation

• The product must be transported in correct method that corresponds to
the weight. Failure to do so may lead to injuries.

• Do not stack the boxes containing inverters higher than the number
recommended.

• The product must be installed to the position where withstands the weight
of the product according to the information in the Instruction Manual.

• Do not install or operate the inverter if it is damaged or has parts missing.
This can result in breakdowns.

• When carrying the inverter, do not hold it by the front cover or setting dial;
it may fall off or fail.

• Do not stand or rest heavy objects on the product.

• The inverter mounting orientation must be correct.

• Foreign conductive bodies must be prevented to enter the inverter. That

includes screws and metal fragments or other flammable substance such
as oil.

• As the inverter is a precision instrument, do not drop or subject it to
impact.

•

The inverter must be used under the follow ing environment: Otherwise the
inverter may be damaged.

(2) Wiring

• Do not install a power factor correction capacitor or surge suppressor on
the inverter output side. These devices on the inverter output side may be
overheated or burn out.

• The connection orientation of the output cables U, V, W to the motor will
affect the direction of rotation of the motor.

(3) Test operation and adjustment

• Before starting operation, each parameter must be confirmed and
adjusted. A failure to do so may cause some machines to make
unexpected motions.

(4) Operation

• Any person must stay away from the equipment when the retry function is
set as it will restart suddenly after trip.

• Since pressing key may not stop output depending on the function

setting status, separate circuit and switch that make an emergency stop
(power OFF, mechanical brake operation for emergency stop, etc.) must
be provided.

• OFF status of the start signal must be confirmed before resetting the
inverter fault. Resetting inverter alarm with the start signal ON restarts the
motor suddenly.

• The inverter must be used for three-phase induction motors.
Connection of any other electrical equipment to the inverter output may
damage the equipment.

• Do not modify the equipment.

• Do not perform parts removal which is not instructed in this manual. Doing

so may lead to fault or damage of the inverter.

CAUTION

WARNING

A-1

• 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.

• Do not use a magnetic contactor on the inverter input for frequent starting/
stopping of the inverter.

• The effect of electromagnetic interference must be reduced by using a
noise filter or by other means. Otherwise nearby electronic equipment
may be affected.

• Appropriate measures must be taken to suppress harmonics. Otherwise
power supply harmonics from the inverter may heat/damage the power
factor correction capacitor and generator.

• When driving a 400V class motor by the inverter, the motor must be an
insulation-enhanced motor or measures must be taken to suppress surge
voltage. Surge voltage attributable to the wiring constants may occur at
the motor terminals, deteriorating the insulation of the motor.

• When parameter clear or all parameter clear is performed, the required
parameters must be set again before starting operations because all
parameters return to the initial value.

• The inverter can be easily set for high-speed operation. Before changing
its setting, the performances of the motor and machine must be fully
examined.

• Stop status cannot be hold by the inverter's brake function. In addition to
the inverter's brake function, a holding device must be installed to ensure
safety.

• Before running an inverter which had been stored for a long period,
inspection and test operation must be performed.

• For prevention of damage due to static electricity, nearby metal must be
touched before touching this product to eliminate static electricity from
your body.

(5) Emergency stop

• A safety backup such as an emergency brake must be provided to prevent
hazardous condition to the machine and equipment in case of inverter
failure.

• When the breaker on the inverter input side trips, the wiring must be
checked for fault (short circuit), and internal parts of the inverter for a
damage, etc. The cause of the trip must be identified and removed before
turning ON the power of the breaker.

• When any protective function is activated, appropriate corrective action
must be taken, and the inverter must be reset before resuming operation.

CAUTION

CAUTION

(6) Maintenance, inspection and parts replacement

• Do not carry out a megger (insulation resistance) test on the control circuit
of the inverter. It will cause a failure.

CAUTION

(7) Disposing of the inverter

• The inverter must be treated as industrial waste.
