This section is specifically about safety matters

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

WARNING

CAUTION

CAUTION

The level may even lead to a serious
consequence according to conditions. Both instruction
levels must be followe d because these are im portant to
personal safety.

1. Electric Shoc k Prevention

Incorrect handling may cause
hazardous conditions, resulting in
death or severe injur y.

Incorrect handling may cause
hazardous conditions, resulting in
medium or slig ht injur y, or may cau se
only material damage.

WARNING

z While power is ON or when the inverter is running, do not

open the front cover. Otherwise you may g et an electric
shock.

z Do not run the inverter with the front cover o r wiring cover

removed. Otherwise you may acces s the exposed hi gh­voltage terminals or the charging part of the circuitry and
get an electric shock.

z Even if power is OFF, do not remove the front cover

except for wiring or periodic in spection. You may
accidentally touch the charged inverter circuits and get an
electric shock.

z Before wiring or inspection, power must be switched OFF.

To confirm that, LED indication of the operation panel
must be checked. (It m ust be OFF.) Any person who is
involved in wiring o r inspection shall wait for at least 10
minutes after the po wer supply has been switched OFF
and check that there are n o residual voltage using a teste r
or the like. The capacitor is charged wit h 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 r egulations and elect rical code (NEC
section 250, IEC 536 class 1 and other applicable
standards). A neutral-point earthed (grounded) power
supply for 400V class inverter in compliance with EN
standard must be used.

z Any person who is involved in wiring or inspection of this

equipment shall be fu lly competent to do the work.

z The inverter must be installed before wiring. Otherwise

you may get an electric shock or be injured.

z Setting dial and key operations must be performed with

dry hands to prevent an electric shock. Ot herwise you
may get an electric s hock.

z Do not subject the cables to scr atches, excessive st ress,

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 or handle the

cables with wet hands. Otherwise you may get an electric
shock.

z When measuring the main c ircuit capacitor capacity, the

DC voltage is applied to the motor for 1s a t powering OFF.
Never touch the motor terminal, etc. right after powe ring
OFF to prevent an el ectric shock.

2. Fire Prevention

CAUTION

z Inverter must be installed on a nonflammable wall without

holes (so that nobody touches the inverter heatsink on the
rear side, etc.). M ounting it to or near flammable mat erial
can cause a fire.

z If the inverter has become faulty, the inverter power mu st

be switched OFF. A continuous flow of large current could
cause a fire.

z

When using a brake resistor, a sequence that will turn OFF
power when a fault s ignal is output mu st be configured.
Otherwise the brake resistor may overheat due to damage
of the brake transistor and possibly cause a fire.

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

and N/-. Doing so could cause a fire.

3.Injury Prevention

CAUTION

z The voltage applied to each terminal must be th e ones

specified in the Instruction Manual. Otherwise burst,
damage, etc. may occur.

z The cables must be connected t o the correct termina ls.

Otherwise burst, damage, etc. may occur.

z Polarity must be correct. Other wise burst, damage, etc.

may occur.

z While power is ON or for some time after power-OFF, do

not touch the in verter since th e inverter will be extremely
hot. Doing so can cause burns.

4. Additional Instructions

Also the following points must be noted to prevent an

accidental failure, injury, electric shoc k, etc.

(1) Transportation and mounting

CAUTION

z The product must be transported in correct method that

corresponds to the weight. Failure to do so may lead to
injuries.

z Do not stack the boxes containing inverters high er than

the number recommended.

z The product must be installed to the position where

withstands the weight of the product according to the
information in the In struction Manual .

z Do not install or operate the inverter if it is damaged or

has parts missing.

z When carrying the inverter, do not hold it by the front

cover or setting dia l; it may fall off or fail .

z Do not stand or rest heavy objects on the product.
z The inverter mounting orientation must be correct.
z Foreign conductive objects must be prevented from

entering the inverter. That includes screws and metal
fragments or other flammable substance such as oil.

z As the inverter is a precision instrument, do not drop or

subject it to impact.

z The inverter must be used under the following

environment: Oth erwise the inverter may be damaged.

CAUTION

z Do not install a power factor cor rection 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 affects th e rotation direction of the motor.

(3) Trial run

CAUTION

z Before starting operation, each parameter must be

confirmed and adjusted. A fa ilure to do so may cause
some machines to ma ke unexpected motions.

(4) Usage

WARNIN

z Any person must stay away from t he equipment when the

retry function is set as it will restart suddenly after trip.

z Since pressing key may not stop output dependi ng

on the function s etting status, separate circuit and switch
that make an emerg ency stop (power OFF, mechanical
brake operation for em ergency stop, etc.) must b e
provided.

z OFF status of the start signal must be confirmed before

resetting the inverter fa ult. Resetting inverter alar m with
the start signal ON restarts the motor suddenly.

z The inverter must be used for three-phase induction

motors. 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.

z The electronic thermal relay function does not guarantee

protection of the motor from overheating. It is
recommended to in stall both an external therm al and PTC
thermistor for over heat protection.

z Do not use a magnetic contactor on the inverter input for

frequent starting/stopping of the inverter. Otherwise the
life of the invert er decreases.

z The effect of electromag netic interference must be

reduced by using an EMC filter or by other means.
Otherwise nearby electronic equipment may be affected.

z Appropriate measures must be taken to suppress

harmonics. Otherwise power supply harmonics from the
inverter may heat/d amage the power fac tor correction
capacitor and generator.

z When driving a 400V class motor by the inver ter, 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.

z When parameter clear or all param eter clear is perf ormed,

the required paramet ers must be set ag ain before starting
operations becaus e all parameters return t o the initial
value.

z 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.

z 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.

z Before running an inverter which had been stored for a

long period, inspection and test operation must be
performed.

z Static electricity in your body must be discharged before

you touch the product. Otherwise the product may be
damaged.

z If you are installing the invert er to drive a three-pha se

device while you are contracted for lighting and power
service, consult your electric power supplier.

(5) Emergency stop

CAUTION

CAUTION

z A safety backup such as an emerg ency brake must be

provided to prevent hazardous condition to the machine
and equipment in c ase of inverter failure.

z 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. Th e cause
of the trip must be i dentified and remo ved before turning
ON the power of t he breaker.

z When any protective func tion is activated, ap propriate

corrective action must be taken, and the inverter must be
reset before resuming 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 fa ilure.

(7) Disposal

CAUTION

z The inverter must be treate d as industrial waste.
