This instruction manual (basic) provides handling information and precautions for use of the equipment.

Please forward this instruction manual (basic) to the end user.

4. Additional Instructions

Also note the following points to prevent an accidental failure, injury, electric

shock, etc.

This section is specifically about safety matters

Do not attempt to install, operate, maintain or inspect the inverter until you

have read through this instruction manual (basic) 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 instruction manual (basic), the safety

instruction levels are classified into "WARNING" and "CAUTION".

Assumes that incorrect handling may cause hazardous

conditions, resulting in death or severe injury.

Assumes that incorrect handling may cause

hazardous conditions, resulting in medium or

slight injury, or may cause physical damage only.

Note that even the level may lead to a serious consequence

according to conditions. Please follow strictly the instructions of both levels

because they are important to personnel safety.

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.m

• Do not run the inverter with the front cover or wiring 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 starting wiring or inspection, 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.

• This inverter must be earthed

(grounded). Earthing (grounding) 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. 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.

2. Fire Prevention

• Mount the inverter to incombustible material. Mounting it to or near

combustible material can cause a fire.

• If the inverter has become faulty, switch off the inverter power.

A continuous flow of large current could cause a fire.

•

Do not connect a resistor directly to the DC terminals P/

, N/

−

. This could cause a fire.

3. Injury Prevention

• Apply only the voltage specified in the instruction manual to each terminal.

Otherwise, burst, damage, etc. may occur.

• Ensure that the cables are connected to the correct terminals. Otherwise,

burst, damage, etc. may occur.

• Always make sure that polarity is correct to prevent damage, etc. Otherwise,

burst, damage, etc. may occur.

• While power is on or for some time after power-off, do not touch the inverter

as it is hot and you may get burnt.

(1) Transportation and installation

• When carrying products, use correct lifting gear to prevent injury.

• Do not stack the inverter boxes higher than the number recommended.

• Ensure that installation position and material can withstand the weight of the

inverter. Install 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.

• Check the inverter mounting orientation is correct.

• Prevent other conductive bodies such as screws and metal fragments or

other flammable substance such as oil from entering the inverter.

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

• Use the inverter under the following environmental conditions. Otherwise, the

inverter may be damaged.

*1 Temperature applicable for a short time, e.g. in transit.

*2 2.9m/s

or less for the 185K or more.

(2) Wiring

• Do not install a power factor correction capacitor, surge suppressor or radio

noise filter on the inverter output side.

• 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, confirm and adjust the parameters. A failure to do

so may cause some machines to make unexpected motions.

(4) Operation

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

will restart suddenly after an alarm stop.

• The 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 inverter as well

as 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.

• 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 factor correction 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 initial

value.

• 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.

• For prevention of damage due to static electricity, touch nearby metal before

touching this product to eliminate static electricity from your body.

(5) Emergency stop

• 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 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.

• When the protective function is activated, take the corresponding corrective

action, then reset the inverter, and resume operation.

(6) Maintenance, inspection and parts replacement

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

the inverter.

(7) Disposing of the inverter

• Treat as industrial waste.

General instructions

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

the inverter without a cover, or partially open. Never run the inverter in this

status. Always replace the cover and follow this instruction manual (basic)

when operating the inverter.
