Safety Precautions

JConfirmations upon Delivery

CAUTION

Page

DNever install an Inverter that is damaged or missing components.

Doing so can result in injury.

2-2

JInstallation

CAUTION

Page

DAlways hold the case when carrying the Inverter.

If the Inverter is held by the front cover, the main body of the Inverter may fall, possibly result-

ing in injury.

2-6

DAttach the Inverter to a metal or other noncombustible material.

Fire can result if the Inverter is attached to a combustible material.

2-6

DInstall a cooling fan or other cooling device when installing more than one Inverter in

the same enclosure so that the temperature of the air entering the Inverters is below

45_C.

Overheating can result in fires or other accidents.

2-6

JWiring

WARNING

Page

DAlways turn OFF the input power supply before wiring terminals.

Otherwise, an electric shock or fire can occur.

3-2

DWiring must be performed by an authorized person qualified in electrical work.

Otherwise, an electric shock or fire can occur.

3-2

DBe sure to ground the ground terminal.

(200 V class: Ground to 100 Ωor less, 400 V class: Ground to 10 Ωor less)

Otherwise, an electric shock or fire can occur.

3-2

DAlways check the operation of any emergency stop circuits after they are wired.

Otherwise, there is the possibility of injury. (Wiring is the responsibility of the user.)

3-2

DNever touch the output terminals directly with your hands or allow the output lines to

come into contact with the Inverter case. Never short the output circuits.

Otherwise, electrical shock or grounding can occur.

3-2

CAUTION

Page

DCheck to be sure that the voltage of the main AC power supply satisfies the rated

voltage of the Inverter.

Injury or fire can occur if the voltage is not correct.

3-2

DDo not perform voltage withstand tests on the Inverter.

Otherwise, semiconductor elements and other devices can be damaged.

3-2

DConnect braking resistors, Braking Resistor Units, and Braking Units as shown in the

I/O wiring examples.

Otherwise, a fire can occur.

3-2

DTighten all terminal screws to the specified tightening torque.

Otherwise, a fire may occur.

3-2

CAUTION

Page

DDo not connect AC power to output terminals U, V, and W.

The interior parts of the Inverter will be damaged if voltage is applied to the output terminals.

3-2

DDo not connect phase-advancing capacitors or LC/RC noise filters to the output cir-

cuits.

The Inverter can be damaged or internal parts burnt if these devices are connected.

3-2

DDo not connect electromagnetic switches or contactors to the output circuits.

If a load is connected while the Inverter is operating, surge current will cause the overcurrent

protection circuit inside the Inverter to operate.

3-2

JSetting User Constants

CAUTION

Page

DDisconnect the load (machine, device) from the motor before autotuning.

The motor may turn, possibly resulting in injury or damage to equipment. Also, motor

constants cannot be correctly set with the motor attached to a load.

4-29

JTrial Operation

WARNING

Page

DCheck to be sure that the front cover is attached before turning ON the power supply.

Do not remove the front cover during operation.

An electric shock may occur.

5-2

DDo not come close to the machine when the fault reset function is used. If the alarmed

is cleared, the machine may start moving suddenly.

Also, design the machine so that human safety is ensured even when it is restarted.

Injury may occur.

5-2

DProvide a separate emergency stop switch; the Digital Operator STOP Key is valid

only when its function is set.

Injury may occur.

5-2

DReset alarms only after confirming that the RUN signal is OFF. If an alarm is reset with

the RUN signal turned ON, the machine may suddenly start.

Injury may occur.

5-2

CAUTION

Page

DDon’t touch the radiation fins (heat sink), braking resistor, or Braking Resistor Unit.

These can become very hot.

Otherwise, a burn injury may occur.

5-2

DBe sure that the motor and machine is within the applicable ranges before starting

operation.

Otherwise, an injury may occur.

5-2

DProvide a separate holding brake if necessary.

Always construct the external sequence to confirm that the holding brake is activated

in the event of an emergency, a power failure, or an abnormality in the inverter occur-

ing.

Failure to observe this caution can result in personal injury.

5-2

DIf using with an elevator, take safety measures on the machine’s side to prevent the

elevator from dropping.

Failure to observe this caution can result in personal injury.

CAUTION

DDon’t check signals while the Inverter is running.

Otherwise, the equipment may be damaged.

5-2

DBe careful when changing Inverter settings. The Inverter is factory set to suitable set-

tings.

Otherwise, the equipment may be damaged. You must, however, you must set the power sup-

ply voltage jumper for 400 V class Inverters of 18.5 kW or higher (see 5.2.4).

JMaintenance and Inspection

WARNING

Page

DDo not touch the Inverter terminals. Some of the terminals carry high voltages and

are extremely dangerous.

Doing so can result in electric shock.

10 - 2

DAlways have the protective cover in place when power is being supplied to the Invert-

er. When attaching the cover, always turn OFF power to the Inverter through the

MCCB.

Doing so can result in electric shock.

10 - 2

DAfter turning OFF the main circuit power supply, wait until the CHARGE indicator light

goes out before performance maintenance or inspections.

The capacitor will remain charged and is dangerous.

10 - 2

DMaintenance, inspection, and replacement of parts must be performed only by au-

thorized personnel.

Remove all metal objects, such as watches and rings, before starting work. Always

use grounded tools.

Failure to heed these warning can result in electric shock.

10 - 2

CAUTION

Page

DA CMOS IC is used in the control board. Handle the control board and CMOS IC care-

fully. The CMOS IC can be destroyed by static electricity if touched directly.

The CMOS IC can be destroyed by static electricity if touched directly.

10 - 2

DDo not change the wiring, or remove connectors or the Digital Operator, during op-

eration.

Doing so can result in personal injury.

10 - 2

JOther

WARNING

DDo not attempt to modify or alter the Inverter.

Doing so can result in electrical shock or injury.
