monitor is off, wait for at least 10 minutes after the power supply has been switched

off, and check to make sure that there are no residual voltage using a tester or the

like.

This inverter must be earthed. Earthing must conform to the requirements of

national and local safety regulations and electrical codes. (JIS, NEC section 250,

IEC 536 class 1 and other applicable standards)

Any person who is involved in the wiring or inspection of this equipment should be

fully competent to do the work.

Always install the inverter before wiring. Otherwise, you may get an electric shock

or be injured.

Perform setting dial and key operations with dry hands to prevent 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 change the cooling fan while power is on. It is dangerous to change the

(2) Wiring

(3) Trial run

(4) Operation

CAUTION

Do not fit capacitive equipment such as power factor correction capacitor, radio

noise filter (option FR-BIF(-H)) 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.

CAUTION

Check all parameters, and ensure that the machine will not be damaged by a

sudden start-up.

When the load GD2is small (at the motor GD or smaller) for 400V from 1.5K to 3.7K, the

output current may vary when the output frequency is in the 20Hz to 30Hz range.

If this is a problem, set the Pr.72 "PWM frequency selection" to 6kHz or higher.

(When setting the PWM to a higher frequency, check for noise or leakage current

problem and take countermeasures against it.)

WARNING

When you have chosen the retry function, stay away from the equipment as it will

restart suddenly after an alarm stop.

The [STOP] key is valid only when the appropriate function setting has been made.

Prepare an emergency stop switch separately.

Make sure that the start signal is off before resetting the inverter alarm. A failure to

do so may restart the motor suddenly.

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.

Do not perform parts removal which is not instructed in this manual. Doing so may

lead to fault or damage of the inverter.

(5) Emergency stop

(6) Maintenance, inspection and parts replacement

(7) Disposing of the inverter

(8) General instructions

CAUTION

The electronic thermal relay function does not guarantee protection of the motor

from overheating.

Do not use a magnetic 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 supply harmonics from

the inverter may heat/damage the power capacitor and generator.

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.

When parameter clear or all clear is performed, reset the required parameters

before starting operations. Each parameter returns to the factory setting.

The inverter can be easily set for high-speed operation. Before changing its

setting, fully examine the performances of the motor and machine.

In addition to the inverter's holding function, install a holding device to ensure safety.

Before running an inverter which had been stored for a long period, always

perform inspection and test operation.

CAUTION

Provide a safety backup such as an emergency brake which will prevent the

machine and equipment from hazardous conditions if the inverter fails.

When the breaker on the inverter primary 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.

When any protective function is activated, take the appropriate corrective action,

then reset the inverter, and resume operation.

CAUTION

Do not carry out a megger (insulation resistance) test on the control circuit of the

inverter.

CAUTION

Treat as industrial waste.

Many of the diagrams and drawings in this instruction manual (detailed) show the inverter

without a cover, or partially open. Never operate the inverter in this manner. Always replace

the cover and follow this instruction manual (detailed) when operating the inverter.
