Thank you for choosing this Mitsubishi Inverter.This Instruction Manual provides instructions for advanced use of the FR-F700 series inverters.Incorrect handling might cause an unexpected fault. Before using the inverter, always read this Instruction Manual Guideline [IB-0600218ENG] packed with the product carefully to use the equipment to its optimum.

1. Electric Shock Prevention

2. Fire Prevention

3. Injury Prevention

4. Additional Instructions Also the following points must be noted toelectric shock, etc.

This section is specifically about safety mattersDo not attempt to install, operate, maintain or inspect the inverter until you have read through Installation Guideline and appendeddocuments carefully and can use the equipment correctly. Do notuse the inverter until you have a full knowledge of the equipment,safety information and instructions. In this Instruction Manual, thesafety instruction levels are classified into "WARNING" and"CAUTION".

Incorrect handling may cause hazardous

conditions, resulting in death or severe injury.Incorrect handling may cause hazardousconditions, resulting in medium or slightinjury, or may cause only material damage.

The level may even lead to a serious consequenceaccording to conditions. Both instruction levels must be followedbecause these are important to personal safety.

While power is ON or when the inverter is running, do not openthe front cover. Otherwise you may get an electric shock.

Do not run the inverter with the front cover or wiring cover removed.Otherwise you may access the exposed high-voltage terminalsor 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 accidentally touch thecharged inverter circuits and get an electric shock.

Before wiring, inspection or switching EMC filter ON/OFFconnector, power must be switched OFF. To confirm that, LEDindication of the operation panel must be checked. (It must beOFF.) Any person who is involved in wiring, inspection or switching EMC filter ON/OFF connector shall wait for at least 10minutes after the power supply has been switched OFF andcheck 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 code (NEC section 250, IEC 536 class1 and other applicable standards). A neutral-point earthed (grounded) power supply for 400V classinverter in compliance with EN standard must be used.

Any person who is involved in wiring or inspection of thisequipment shall be fully competent to do the work.

The inverter must be installed before wiring. Otherwise you mayget an electric shock or be injured.

(2) Wiring

Do not install a power factor correction capacitor, surgesuppressor or capacitor type filter on the inverter output side.These devices on the inverter output side may be overheated or burn out.

The connection orientation of the output cables U, V, W to themotor affects the rotation direction of the motor.

(3) Test operation and adjustment

Before starting operation, each parameter must be confirmed andadjusted. A failure to do so may cause some machines to makeunexpected motions.

(4) Operation

Any person must stay away from the equipment when the retryfunction is set as it will restart suddenly after trip.

Since pressing key may not stop output depending on thefunction setting status, separate circuit and switch that make anemergency stop (power OFF, mechanical brake operation for emergency stop, etc.) must be provided.

OFF status of the start signal must be confirmed before resettingthe inverter fault. Resetting inverter alarm with the start signalON restarts the motor suddenly.

The inverter must be used for three-phase induction motors.Connection of any other electrical equipment to the inverter output may damage the 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 guaranteeprotection of the motor from overheating. It is recommended toinstall both an external thermal and PTC thermistor for overheatprotection.

Do not use a magnetic contactor on the inverter input for frequentstarting/stopping of the inverter. Otherwise the life of the inverter decreases.

The effect of electromagnetic interference must be reduced byusing a noise filter or by other means. Otherwise nearbyelectronic equipment may be affected.

Appropriate measures must be taken to suppress harmonics.Otherwise power supply harmonics from the inverter may heat/damage the power factor correction capacitor and generator.

When driving a 400V class motor by the inverter, the motor mustbe an insulation-enhanced motor or measures must be taken tosuppress surge voltage. Surge voltage attributable to the wiringconstants may occur at the motor terminals, deteriorating theinsulation of the motor

1.4 Installation of the inverter and enclosure design

When an inverter enclosure is to be designed and manufactured, heat generated by contained equipmenenvironment of an operating place, and others must be fully considered to determine the enclosure structu

equipment layout. The inverter unit uses many semiconductor devices. To ensure higher reliability and looperation, operate the inverter in the ambient environment that completely satisfies the equipment specific

1.4.1 Inverter installation environment

As the inverter installation environment should satisfy the standard specifications indicated in the fooperation in any place that does not meet these conditions not only deteriorates the performance aninverter, but also causes a failure. Refer to the following points and take adequate measures.

* 2.9m/s 2 or less for the FR-F740-04320 or higher.

(1) Temperature

The permissible surrounding air temperature of the inverter is -10 C (14F) to +50 C (122F)(14F) to +40 C (104F) (when SLD is set). Always operate the inverter within this temperature range. Othis range will considerably shorten the service lives of the semiconductors, parts, capacitors and othefollowing measures so that the surrounding air temperature of the inverter falls within the specified range.1) Measures against high temperature

Use a forced ventilation system or similar cooling system. (Refer to page 10.) Install the enclosure in an air-conditioned electrical chamber. Block direct sunlight. Provide a shield or similar plate to avoid direct exposure to the radiated heat and wind of a heat sour Ventilate the area around the enclosure well.

2) Measures against low temperature Provide a space heater in the enclosure. Do not power OFF the inverter. (Keep the start signal of the inverter OFF.)

3) Sudden temperature changes Select an installation place where temperature does not change suddenly. Avoid installing the inverter near the air outlet of an air conditioner. If temperature changes are caused by opening/closing of a door, install the inverter away from the do

(2) Humidity

Normally operate the inverter within the 45 to 90% range of the ambient humidity. Too high humidity willof reduced insulation and metal corrosion. On the other hand, too low humidity may produce a spabreakdown. The insulation distance specified in JEM1103 "Control Equipment Insulator" is defined as h

(3) Dust, dirt, oil mist

Dust and dirt will cause such faults as poor contact of contact points, reduced insulation or reduced cto moisture absorption of accumulated dust and dirt, and in-enclosure temperature rise due to clogged In the atmosphere where conductive powder floats, dust and dirt will cause such faults as malfunctinsulation and short circuit in a short time.Since oil mist will cause similar conditions, it is necessary to take adequate measures.

Countermeasures Place in a totally enclosed enclosure.

Take measures if the in-enclosure temperature rises. (Refer to page 10.) Purge air.

Pump clean air from outside to make the in-enclosure pressure higher than the outside-air pressure.

(4) Corrosive gas, salt damage

If the inverter is exposed to corrosive gas or to salt near a beach, the printed board patterns and partsthe relays and switches will result in poor contact.In such places, take the measures given in Section (3) .

(5) Explosive, flammable gases

As the inverter is non-explosion proof, it must be contained in an explosion proof enclosure.

In places where explosion may be caused by explosive gas, dust or dirt, an enclosure cannot bestructurally complies with the guidelines and has passed the specified tests. This makes the enclosure (including the test charges).The best way is to avoid installation in such places and install the inverter in a non-hazardous place.

(6) Highland

Use the inverter at the altitude of within 1000m (3280.80 feet).If it is used at a higher place, it is likely that thin air will reduce the cooling effect and low air press

dielectric strength.

(7) Vibration, impact

The vibration resistance of the inverter is up to 5.9m/s 2 (2.9m/s 2 for the FR-F740-0432frequency (directions of X, Y, Z axes) and 1mm (0.04 inches) amplitude.Vibration or impact, if less than the specified value, applied for a long time may make the mechanismpoor contact to the connectors.Especially when impact is imposed repeatedly, caution must be taken as the part pins are likely to brea

Countermeasures Provide the enclosure with rubber vibration isolators. Strengthen the structure to prevent the enclosure from resonance. Install the enclosure away from sources of vibration.

1.4.2 Cooling system types for inverter enclosure

From the enclosure that contains the inverter, the heat of the inverter and other equipment (transformresistors, etc.) and the incoming heat such as direct sunlight must be dissipated to keep the in-enclosure t

lower than the permissible temperatures of the in-enclosure equipment including the inverter.The cooling systems are classified as follows in terms of the cooling calculation method.1) Cooling by natural heat dissipation from the enclosure surface (Totally enclosed type)2) Cooling by heatsink (Aluminum heatsink, etc.)3) Cooling by ventilation (Forced ventilation type, pipe ventilation type)4) Cooling by heat exchanger or cooler (Heat pipe, cooler, etc.)

(2) Clearances around the inverter

To ensure ease of heat dissipation and maintenance, leave at least the shown clearances around the invthe following clearances are required under the inverter as a wiring space, and above the inverter as a hspace.

(3) Inverter mounting orientation

Mount the inverter on a wall as specified. Do not mount it horizontally or any other way.

(4) Above the inverter

Heat is blown up from inside the inverter by the small fan built in the unit. Any equipment placed should be heat resistant.

(5) Arrangement of multiple inverters

REMARKS For replacing the cooling fan of the FR-F740-04320 or higher, 30cm(11.8 inches) of space is nece

the inverter. Refer to page 359 for fan replacement.

When multiple inverters are placed in the sameenclosure, generally arrange them horizontally asshown in the right figure (a). When it is inevitable toarrange them vertically to minimize space, take suchmeasures as to provide guides since heat from thebottom inverters can increase the temperatures in thetop inverters, causing inverter failures.

When mounting multiple inverters, fully take cautionnot to make the surrounding air temperature of theinverter higher than the permissible value by providingventilation and increasing the enclosure size.

(2) Notes on earthing (grounding)

Always earth (ground) the motor and inverter.1)Purpose of earthing (grounding)

Generally, an electrical apparatus has an earth (ground) terminal, which must be connected to th

use. An electrical circuit is usually insulated by an insulating material and encased. However, manufacture an insulating material that can shut off a leakage current completely, and actually, a sinto the case. The purpose of earthing (grounding) the case of an electrical apparatus is to prevegetting an electric shock from this leakage current when touching it.To avoid the influence of external noises, this earthing (grounding) is important to audio eqcomputers and other apparatuses that handle low-level signals or operate very fast.

2)Earthing (Grounding) methods and earthing (grounding) work As described previously, earthing (grounding) is roughly classified into an electrical shock prevnoise-affected malfunction prevention type. Therefore, these two types should be discriminatefollowing work must be done to prevent the leakage current having the inverter's high frequencyentering the malfunction prevention type earthing (grounding):(a) If possible, use (l) independent earthing (grounding) in figure below for the inv

earthing(grounding) is not available, use (ll) common earthing (grounding) in the figuinverter is connected with the other equipment at an earthing (grounding) point.The (lll) common earthing (grounding) as in the figure below, which inverter shares (grounding) cable with the other equipment, must be avoided.

A leakage current including many high frequency components flows in the earthing (grouninverter and inverter-driven motor. Therefore, use the independent earthing (groundingearthing (grounding) cable of the inverter from equipment sensitive to EMI.In a high building, it may be effective to use the EMI prevention type earthing (groundiniron structure frame, and electric shock prevention type earthing (grounding) with the in(grounding) together.

(b) This inverter must be earthed (grounded). Earthing (Grounding) must conform to the requiand local safety regulations and electrical code (NEC section 250, IEC 536 class 1 anstandards).

A neutral-point earthed (grounded) power supply for 400V class inverter in compliance witbe used.

(c) Use the thickest possible earthing (grounding) cable. The earthing (grounding) cable size than the size indicated in the table on the previous page.

(d) The earthing (grounding) point should be as close as possible to the inverter, and the earwire length should be as short as possible.

(e) Run the earthing (grounding) cable as far away as possible from the I/O wiring of equnoises and run them in parallel in the minimum distance.

To be compliant with the EU Directive (Low Voltage Directive) refer to the

When connecting the brake unit (FR-BU(H)/MT-BU5) to improve the brake capability at deceleration, maas shown below.(1) Connection with the FR-BU (FR-F720-02330 (FR-F740-01160) or lower)

(2) Connection with the MT-BU5 (FR-F720-03160 (FR-F740-01800) or higher) After making sure that the wiring is correct, set "1" in Pr.30 Regenerative function selection . ( R

*1 Connect the inverter terminals (P/+, N/-) and brake unit (FR-BU (H)) terminals so that their terminal signalwith each other. (Incorrect connection will damage the inverter.)

*2 When the power supply is 400V class, install a step-down transformer.*3 The wiring distance between the inverter, brake unit (FR-BU) and resistor unit (FR-BR) should be within

feet). If twisted wires are used, the distance should be within 10m(32.8feet).

CAUTIONIf the transistors in the brake unit should become faulty, the resistor can be unusually hot, causing a fire. Therefomagnetic contactor on the inverters input side to configure a circuit so that a current i s shut off in case of fault.Do not remove a jumper across terminal P/+ and P1 except when connecting a DC reactor.
