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.

1. Electric Shock Prevention

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 or wiring cover

removed. Otherwis e you may acces s the exposed highvoltage 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 wirin g or periodic in spection. You may access the charged inver ter circuits and get an el ectric shock.

z Before wiring or insp ection, 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 wa it for at least 10 minutes after the power supply has been switched OFF and check that there are n o residual voltage using a teste r or the like. The capacitor is charg ed with high vol tage 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 regulations an d electrical code (NEC section 250, IEC 536 class 1 and other applicable standards). A neutral-point earthed (grounded) power supply for 400V class inverter in comp liance with EN standard m ust 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 c ables to scratches, excessive stress,

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 with wet hands.

Otherwise you may g et an electric shock.

z When measuring t he main circuit capaci tor capacity, the

DC voltage is applied to t he motor for 1s at powering OFF. Never touch the motor terminal, etc. right after powering OFF to prevent an e lectric 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 h as become faulty, the inverte r power must

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

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 excessively overheat due to damage of the brake transistor and such, causing a fire.

z Do not connect a resi stor directly to the DC t erminals P/+

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

A-1

3.Injury Prevention

CAUTION

z The voltage applied to each te rminal must be the ones

specified in the I nstruction Manual. O therwise burst, damage, etc. may occur.

z The cables must be connected to the cor rect terminals.

Otherwise burst, damage, etc. may occur.

z Polarity must be co rrect. Otherwise b urst, damage, etc.

may occur.

z 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.

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 inv erters higher 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 dial; 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 bodies must be prevented to enter the

inverter. That includes screws and m etal 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: Otherwise the inverter may be damaged.

Surrounding air temperature

Ambient humidity

Storage temperature

Atmosphere

Environment

Maximum 1,000m above sea level.

or less at 10 to 55Hz (directions of X, Y, Z

5.9m/s axes)

(2) Wiring

CAUTION

z Do not install a power fac tor correction 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 failure to do so may cause some machines to ma ke unexpected motions.

(4) Usage

WARNING

z Any person must s tay away from the equip ment 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 setting status, separate circuit and switch that make an em ergency stop (power OFF, mechanical brake operation for em ergency stop, etc.) must be provided.

z OFF status of the start signal must be confirmed before

resetting the inverte r fault. Resetting inverte r alarm with the start signal ON restarts the motor suddenly.

z The inverter must b e 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.

CAUTION

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 elect romagnetic interf erence 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 mo tor 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.

z When parameter clear or all parameter clear i s performed,

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 For prevention of damage due to static electricity, nearby

metal must be touched before touching this product to eliminate static electricity from your body.

A-2

(5) Emergency stop

CAUTION

z A safety backup such as an em ergency brake must b e

provided to prevent hazardous condition to the machine and equipment in ca se 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 identified and removed before turning ON the power of the breaker.

z When any protective function is activated, appropriate

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 fai lure.

(7) Disposal

CAUTION

z The inverter must be treated as industrial waste.

NOTE

y When the inverter capacity is larger than the motor capacity, select an MCCB and a magnetic contactor according to the inverter model

and cable and reactor according to the motor output.

y 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.

The line voltage drop can be calculated by the following formula:

Line voltage drop [V]=

Use a larger diameter cable when the wiring distance is long or when it is desired to decrease the voltage drop (torque

reduction) in the low speed range.

(2) Earthing (Grounding) precautions

Leakage currents flow in the inverter. To prevent an electric shock, the inverter and motor must be earthed (grounded). This

inverter must be earthed (grounded). Earthing (Grounding) must conform to the requirements of national and local safety

regulations and electrical codes. (NEC section 250, IEC 536 class 1 and other applicable standards)

Use an neutral-point earthed (grounded) power supply for 400V class inverter in compliance with EN standard.

Use the dedicated earth (ground) terminal to earth (ground) the inverter. (Do not use the screw in the casing, chassis, etc.)

Use the thickest possible earth (ground) cable. Use the cable whose size is equal to or greater than that indicated on page

12 , and minimize the cable length. The earthing (grounding) point should b e as near as possible to the inverter.

POINT

To be compliant with the EU Directive (Low Voltage Directive), earth (ground) the inverter according to the

instructions on page 133.

When driving a 400V class motor by the inverter, surge voltages attributable to the wiring constants may occur at the

motor terminals, deteriorating the insulation of the motor. Take the following measures 1) or 2) in this case.

1) Use a "400V class inverter-driven insulation-enhanced motor" and set frequency in Pr. 72 PWM frequency selection

according to wiring length

Wiring Length

50m or less 50m to 100m Exceeding 100m

Carrier frequency

2) Connect the surge voltage suppression filter (FR-ASF-H/FR-BMF -H) on the inverter outpu t side.

NOTE

 Especially for long-distance wiring, the inverter may be affected by a charging current caused by the stray

capacitances of the wiring, leading to a malfunction of the overcurrent protective function, fast response current limit function, or stall prevention function or a malfunction or fault of the equipment connected on the inverter output side. If malfunction of fast-response current limit function occurs, disable this function. If malfunction of stall prevention

function occurs, increa se the stall level. ( Refer to Pr. 22 Stall prevention operation level and Pr. 156 Stall prevention

2.4.5 Changing the control logic

NOTE

 Fully make sure that th e front cover has bee n reinstalled securely.

 The capacity plate is placed on the front cover and the rat ing plate is on the invert er. Since these plates have the

same serial numbers, always reinstall the remove d cover onto the original inverter.

 The sink-source logic change-over jumper connector must be fitted in only one of those positions. If it is fitted in both

positions at the same time, the inverter may be damaged.

Wiring

The input signals are set to sink logic (SINK) when shipped from

the factory.

To change the control logic, the jumper connector above the

control terminal must be moved to the other position.

Change the jumper connector in the sink logic (SINK) position

to source logic (SOURCE) position using tweezers, a pair of

long-nose pliers etc. Change the jumper connector position

before switching power ON.

(2) Wiring method

zWiring

Use a blade terminal and a wire with a sheath stripped off for the control circuit wiring. For a single wire, strip off the sheath of the wire and apply directly. Insert the blade terminal or the single wire into a socket of the terminal.

1) Strip off the sheath about the length below. If the length of the sheath peeled is too long, a short circuit may occur among neighboring wires. If the length is too short, wires might come off. Wire the stripped wire after twisting it to prevent it from becoming loose. In addition, do not solder it.

2) Crimp the blade terminal.

Insert wires to a blade terminal, and check that the wires come out for about 0 to 0.5 mm from a sleeve. Check the condition of the blade terminal a fter crimping. Do not use a blade terminal of which th e crimping is inappropriate, or the face is damaged.

(3) Control circuit common terminals (SD, 5, SE)

Terminals SD, SE and 5 are common terminals for I/O signals.(All common terminals are isolated from each other.) Do not

earth them. Avoid connecting the terminal SD and 5 and the terminal SE and 5.

Terminal is a common terminal for the contact input terminals (STF, STR, RH, RM, RL) and frequency output signal (FM). The

open collector circuit is isolated from the internal control circuit by photocoupler

Terminal 5 is a common terminal for the frequency setting signals (terminals 2 or 4). It should be protected from external nois e

using a shielded or twisted cable.

Terminal SE is a common terminal for the open collector output terminal (RUN). The contact input circuit is isolated from the

internal control circuit by photocoupler.

(4) Signal inputs by contactless switches

The contacted input terminals of the inverter (STF, STR,

RH, RM, RL) can be controlled using a transistor

instead of a contacted switch as shown on the right.

External signal input using transistor

(5) Wiring instructions

1) It is recommended to use the cables of 0.3mm2 to 0.75mm2 gauge for connection to the control circuit terminals.

2) The maximum wiring length should be 30m (200m for terminal FM).

3) Do not short across terminals PC and SD. Inverter may be damaged.

4) Use two or more parallel micro-signal contacts or twin contacts to prevent contact faults when using contact inputs since the control circuit input signals are micro-currents.
