SAFETY INSTRUCTIONS

1. Electric Shock Prevention WARNING

While power is on or when the inverter is running, do not open the front cover. You may get an electric shock.

Do not run the inverter with the front cover removed. Otherwise, you may access the exposed high- voltage terminals or the charging part of the circuitry and get an electric shock.

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, switch power off, wait for more than at least 10 minutes and check for the presence of any residual voltage with a meter (check chapter 2 for further details.) etc.

Earth the inverter. 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. Operate the switches 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. To do so will invite a hazardous condition.

2. Fire Prevention CAUTION

Mount the inverter on an incombustible surface. Installing the inverter directly on or near a combustible surface could lead to 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 CAUTION

Apply only the voltage specified in the instruction manual to each terminal to prevent damage etc. Ensure that the cables are connected to the correct terminals. Otherwise, damage etc. may occur. Always make sure that polarity is correct to prevent damage etc. After the inverter has been operating for a relativly long period of time, do not touch the inverter as it

may be hot and you may get burnt.

4. Additional instructions Also note the following points to prevent an accidental failure, injury, electric shock, etc.:

(1) Transportation and installation CAUTION

Since the inverter is non-explosion-proof, always install it in a non-hazardous place. 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 operate if the inverter is damaged or has parts missing. Do not hold the inverter by the front cover; it may fall off. Do not stand or rest heavy objects on the inverter. Check the inverter mounting orientation is correct. Prevent screws, wire fragments, conductive bodies, oil or other flammable substances from entering

the inverter. Do not drop the inverter, or subject it to impact. Use the inverter under the following environmental conditions:

Ambient temperature -10C to +50C (non-freezing) (-10C to +40C when using the dirt-protection structure attachment)

Ambient humidity 90%RH or less (non-condensing) Storage temperature -20C to +65C* Ambience Indoors (free from corrosive gas, flammable gas, oil mist, dust and dirt)

En vi

ro nm

en t

Altitude, vibration Maximum 1000m above sea level for standard operation. 5.9 m/s2 or less (conforming to JIS C0911)

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

(2) Wiring CAUTION

Do not fit capacitive equipment such as a power factor correction capacitor, radio noise filter 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.

(3) Trial run CAUTION

Run the FR-B3 under advanced magnetic flux vector control. Check all parameters, and ensure that the machine will not be damaged by a sudden start-up.

(4) Operation CAUTION

Since this inverter is used in combination with the Mitsubishi inverter-driven, pressure-resistant, explosion-proof motor, note the driven motor used with the inverter.

Note that this inverter cannot be used with the Mitsubishi increased-safety, explosion-proof motor. 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.

Page 5

A - 4

CAUTION 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 inverter. The electronic overcurrent protection 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 harmonics from the inverter may

heat/damage the power capacitor and generator. When parameter clear or all clear is performed, each parameter returns to the factory setting. Re-set

the required parameters before starting operation. The inverter can be easily set for high-speed operation. Before changing its setting, examine the

performance 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.

(5) Emergency stop CAUTION

Provide a safety backup such as an emergency brake which will prevent the machine and equipment from hazardous conditions if the inverter fails.

(6) Maintenance, inspection and parts replacement CAUTION

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

(7) Disposing of the inverter CAUTION

Treat as industrial waste.

(8) General instructions Many of the diagrams and drawings in this instruction manual show the inverter without a cover, or partially open. Never run the inverter like this. Always replace the cover and follow this instruction manual when operating the inverter.

1.2 Basic Configuration

1.2.1 Basic configuration The following devices are required to operate the inverter. Proper peripheral devices must be selected and correct connections made to ensure proper operation. Incorrect system configuration and connections can cause the inverter to operate improperly, its life to be reduced considerably, and in the worst case, the inverter to be damaged. Please handle the inverter properly in accordance with the information in each section as well as the precautions and instructions of this manual. (For connections of the peripheral devices, refer to the corresponding manuals.)

Name Description

Power supply Use the power supply within the permissible power supply specifications of the inverter. (Refer to page 194.)

Earth leakage circuit breaker (ELB) or no-fuse breaker (NFB)

The breaker should be selected with care since a large inrush current flows in the inverter at power on. (Refer to page 38.)

Magnetic contactor

The magnetic contactor need not be provided. When installed, do not use it to start or stop the inverter. It might reduce the inverter life. (Refer to page 38.)

Reactors

The reactors must be used when the power factor is to be improved or the inverter is installed near a large power supply system (1000kVA or more and wiring distance within 10m). Make selection carefully.

Inverter

The inverter life is influenced by ambient temperature. The ambient temperature should be as low as possible within the permissible range. This must be noted especially when the inverter is installed in an enclosure. (Refer to page 7.)

Incorrect wiring might lead to inverter damage. The control signal lines should be kept away from the main circuit to protect them from noise. (Refer to page 9.)

Devices connected to the output

Do not connect a power capacitor, surge suppressor or radio noise filter to the output side.

(NFB) or

(ELB)

AC reactor (FR-BAL)

Ground

To prevent an electric shock, always ground the motor and inverter. The ground wiring from the power line of the inverter as an induction noise reduction technique is recommended to be run by returning it to the ground terminal of the inverter. (Refer to page 36)

Japanese Harmonic Suppression Guideline

The "harmonic suppression guideline for household appliances and general-purpose products" was issued by the Ministry of International Trade and Industry in September, 1994. This guideline applies to the FR-B, B3-750 to 3700 (200V class). By connection of the power factor improving reactor (FR-BEL or FR-BAL), this product conforms to the "harmonic suppression technique for transistorized inverters (input current 20A or less)" set forth by the Japan Electrical Manufactures' Association.

2 INSTALLATION AND WIRING2.1 Installation

Since the inverter is non-explosion-proof, always install it in a non-hazardous place.

2.1.1 Instructions for installation 1) Handle the unit carefully.

The inverter uses plastic parts. Handle it gently to protect it from damage. Also, hold the unit with even strength and do not apply too much strength to the front cover alone.

2) Install the inverter in a place where it is immune to vibration. (5.9 m/s2 or less) Also note the cart, press, etc.

3) Note on ambient temperature The inverter life is under great influence of ambient temperature. In the place of installation, ambient temperature must be within the permissible range (-10C to 50C). Check that the ambient temperature is within that range in the positions shown in figure 3).

4) Install the inverter on a non-combustible surface. The inverter will be very hot (maximum about 150C). Install it on a non-combustible surface (e.g. metal). Also leave sufficient clearances around the inverter.

5) Avoid high temperature and high humidity. Avoid direct sunlight and places of high temperature and high humidity.

6) The amount of heat generated in an enclosure can be reduced considerably by placing the heat sink outside the enclosure.

Note: 1. Use the option (FR-A5CN ) for installation. The mounting area should be cut to the panel cutting dimensions.

2. The cooling section outside the enclosure has the cooling fan. Do not use the inverter in any environment where it is exposed to waterdrops, oil mist, dust, etc.

7) Avoid places where the inverter is exposed to oil mist, flammable gases, fluff, dust, dirt etc. Install the inverter in a clean place or inside a "totally enclosed" panel which does not accept any suspended matter.

8) Note the cooling method when the inverter is installed in an enclosure. When two or more inverters are installed or a ventilation fan is mounted in an enclosure, the inverters and ventilation fan must be installed in proper positions with extreme care taken to keep the ambient temperatures of the inverters below the permissible value. If they are installed in improper positions, the ambient temperatures of the inverters will rise and ventilation effect will be reduced.

9) Install the inverter securely with screws or bolts in the vertical direction.
