PRECAUTIONS FOR

MAINTENANCE AND INSPECTION

SPECIFICATIONS

Thank you for choosing this Mitsubishi Inverter. This Instruction Manual (Applied) provides instructions for advanced use of the FR-F700P series inverters. Incorrect handling might cause an unexpected fault. Before using the inverter, always read this Instruction Manual and the Instruction Manual (Basic) [IB-0600411ENG] packed with the product carefully to use the equipment to its optimum.

This section is specifically about safety matters

Do not attempt to install, operate, maintain or inspect the inverter until you have read through 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, the safety instruction levels are classified into "WARNING" and "CAUTION".

WARNING

CAUTION

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

Incorrect handling may cause hazardous conditions, resulting in medium or slight injury, or may cause only material damage.

CAUTION

The level may even lead to a serious consequence according to conditions. Both instruction levels must be followed because these are important to personal safety.

1.Electric Shock Prevention

WARNING

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

the 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 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 accidentally touch the charged inverter circuits and get an electric shock.

• Before wiring, inspection or switching EMC filter ON/OFF

connector, power must be switched OFF. To confirm that, LED indication of the operation panel must be checked. (It must be OFF.) Any person who is involved in wiring, inspection or switching EMC filter ON/OFF connector shall 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 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.

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

equipment shall be fully competent to do the work.

• The inverter must be installed before wiring. Otherwise you may

get an electric shock or be injured.

• Setting dial and key operations must be performed 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 or handle the cables with

wet hands. Otherwise you may get an electric shock.

• When measuring the main circuit capacitor capacity (Pr. 259 Main

circuit capacitor life measuring = "1"), the DC voltage is applied to

the motor for 1s at powering OFF. Never touch the motor terminal, etc. right after powering OFF to prevent an electric shock.

• IPM motor is a synchronous motor with high-performance

magnets embedded in the rotor. Motor terminals hold highvoltage while the motor is running even after the inverter power is turned OFF. Before wiring or inspection, the motor must be confirmed to be stopped. When the motor is driven by the load in applications such as fan and blower, a low-voltage manual contactor must be connected at the inverter's output side, and wiring and inspection must be performed while the contactor is open. Otherwise you may get an electric shock.

2. Fire Prevention

CAUTION

• Inverter must be installed on a nonflammable wall without holes

(so that nobody touches the inverter heatsink on the rear side, etc.). Mounting it to or near flammable material can cause a fire.

• If the inverter has become faulty, the inverter power must be

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

• Do not connect a resistor directly to the DC terminals P/+ and N/

-. Doing so could cause a fire.

3. Injury Prevention

CAUTION

• The voltage applied to each terminal must be the ones specified

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

• The cables must be connected to the correct terminals.

Otherwise burst, damage, etc. may occur.

• Polarity must be correct. Otherwise burst, damage, etc. may

occur.

• 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 shock, etc.

(1) Transportation and installation

CAUTION

• The product must be transported in correct method that

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

• Do not stack the boxes containing inverters higher than the

number recommended.

• The product must be installed to the position where withstands

the weight of the product 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.

• The inverter mounting orientation must be correct.

• Foreign conductive objects must be prevented from entering the

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

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

to impact.

• The inverter must be used under the following environment:

Otherwise the inverter may be damaged.

Surrounding air temperature

Ambient humidity 90% RH or less (non-condensing) Storage temperature -20°C to +65°C

Atmosphere

Environment

Altitude, vibration

*1 Temperature applicable for a short time, e.g. in transit. *2 2.9m/s

or less for the 185K or higher.

-10°C to +50°C (non-freezing)

Indoors (free from corrosive gas, flammable gas, oil mist, dust and dirt)

Maximum 1000m above sea level for standard operation. 5.9m/s

to 55Hz (directions of X, Y, Z axes)

*2 or less at 10

A-1

(2) Wiring

• Do not install a power factor correction capacitor, surge

suppressor 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 the

motor affects the rotation direction of the motor.

• IPM motor terminals (U, V, W) hold high-voltage while the IPM

motor is running even after the power is turned OFF. Before wiring, the IPM motor must be confirmed to be stopped. Otherwise you may get an electric shock.

• Never connect an IPM motor to the commercial power supply.

Applying the commercial power supply to input terminals (U,V, W) of an IPM motor will burn the IPM motor. The IPM motor must be connected with the output terminals (U, V, W) of the inverter.

(3) Test operation and adjustment

• Before starting operation, each parameter must be confirmed

and adjusted. A failure to do so may cause some machines to make unexpected motions.

(4) Operation

• The IPM motor capacity must be same with the inverter capacity.

(The 0.75K inverter can be used with a one-rank lower MM-EF motor.)

• Do not use multiple IPM motors with one inverter.

• Any person must stay away from the equipment when the retry

function is set as it will restart suddenly after trip.

• Since pressing key may not stop output depending on the

function setting status, separate circuit and switch that make an emergency stop (power OFF, mechanical brake operation for emergency stop, etc.) must be provided.

• OFF status of the start signal must be confirmed before resetting

the inverter fault. Resetting inverter alarm with the start signal ON restarts the motor suddenly.

• Do not use an IPM motor in an application where a motor is

driven by its load and runs at a speed higher than the maximum motor speed.

• A dedicated IPM motor must be used under IPM motor control.

Do not use a synchronous motor, induction motor, or synchronous induction motor under IPM motor control.

• The inverter must be used for three-phase induction motors or

the dedicated IPM motor. 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.

CAUTION

WARNING

CAUTION

• The electronic thermal relay function does not guarantee

protection of the motor from overheating. It is recommended to install both an external thermal and PTC thermistor for overheat protection.

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

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

• The effect of electromagnetic interference must be reduced by

using a noise filter or by other means. Otherwise nearby electronic 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 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.

• When parameter clear or all parameter clear is performed, the

required parameters must be set again before starting operations because all parameters return to the initial value.

• 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.

• 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.

• Before running an inverter which had been stored for a long

period, inspection and test operation must be performed.

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

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

• Do not connect an IPM motor under the general-purpose motor

control settings (initial settings). Do not use a general-purpose motor under the IPM motor control settings. Doing so will cause a failure.

• In the system with an IPM motor, the inverter power must be

turned ON before closing the contacts of the contactor at the output side.

(5) Emergency stop

• A safety backup such as an emergency brake must be provided

to prevent hazardous condition to the machine and equipment in case of inverter failure.

• 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. The cause of the trip must be identified and removed before turning ON the power of the breaker.

• When any protective function is activated, appropriate corrective

action must be taken, and the inverter must be reset before resuming operation.

CAUTION

A-2

(6) Maintenance, inspection and parts replacement

CAUTION

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

control circuit of the inverter. It will cause a failure.

(7) Disposing of the inverter

CAUTION

• The inverter must be treated as industrial waste.

1.2 Inverter and peripheral devices

Inverter and peripheral devices

Three-phase AC power supply

Use within the permissible power supply specifications of the inverter.

(Refer to page 346)

Moulded case circuit breaker (MCCB) or earth leakage circuit breaker (ELB), fuse

The breaker must be selected carefully since an in-rush current flows in the inverter at power on.

(Refer to page 4)

Magnetic contactor(MC)

Install the magnetic contactor to ensure safety. Do not use this magnetic contactor to start and stop the inverter. Doing so will cause the inverter life to be shortened.

(Refer to page 4)

Reactor (FR-HAL, FR-HEL)

Install reactors to suppress harmonics and to improve the power factor. An AC reactor (FR-HAL) (option) is required when installing the inverter near a large power supply system (1000kVA or more). The inverter may be damaged if you do not use reactors. Select the reactor according to the model. For the 55K or lower, remove the jumpers across terminals P/+ and P1 to connect to the DC reactor.

(Refer to page 4.)

AC reactor (FR-HAL)

DC reactor (FR-HEL)

Installation of the inverter and

enclosure design

1.4 Installation of the inverter and enclosure design

When an inverter enclosure is to be designed and manufactured, heat generated by contained equipment, etc., the environment of an operating place, and others must be fully considered to determine the enclosure structure, size and equipment layout. The inverter unit uses many semiconductor devices. To ensure higher reliability and long period of operation, operate the inverter in the ambient environment that completely satisfies the equipment specifications.

1.4.1 Inverter installation environment

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

Environmental standard specifications of inverter

The permissible surrounding air temperature of the inverter is between -10°C and +50°C. Always operate the inverter within this temperature range. Operation outside this range will considerably shorten the service lives of the semiconductors, parts, capacitors and others. Take the following 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 source.

• 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 door.

(2) Humidity

Normally operate the inverter within the 45 to 90% range of the ambient humidity. Too high humidity will pose problems of reduced insulation and metal corrosion. On the other hand, too low humidity may produce a spatial electrical breakdown. The insulation distance specified in JEM1103 "Control Equipment Insulator" is defined as humidity 45 to 85%.

1)Measures against high humidity

• Make the enclosure enclosed, and provide it with a hygroscopic agent.

• Take dry air into the enclosure from outside.

• Provide a space heater in the enclosure.

2)Measures against low humidity What is important in fitting or inspection of the unit in this status is to discharge your body (static electricity) beforehand and keep your body from contact with the parts and patterns, besides blowing air of proper humidity into the enclosure from outside.

3)Measures against condensation Condensation may occur if frequent operation stops change the in-enclosure temperature suddenly or if the outsideair temperature changes suddenly. Condensation causes such faults as reduced insulation and corrosion.

• Take the measures against high humidity in 1).

• Do not power off the inverter. (Keep the start signal of the inverter OFF.)

Installation of the inverter and

enclosure design

(3) Dust, dirt, oil mist

Dust and dirt will cause such faults as poor contact of contact points, reduced insulation or reduced cooling effect due to moisture absorption of accumulated dust and dirt, and in-enclosure temperature rise due to clogged filter. In the atmosphere where conductive powder floats, dust and dirt will cause such faults as malfunction, deteriorated insulation 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 parts will corrode or the 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 be used unless it structurally complies with the guidelines and has passed the specified tests. This makes the enclosure itself expensive (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. If it is used at a higher place, it is likely that thin air will reduce the cooling effect and low air pressure will deteriorate dielectric strength.

(7) Vibration, impact

The vibration resistance of the inverter is up to 5.9m/s2 (2.9m/s2 for the 185K or higher) at 10 to 55Hz frequency (directions of X, Y, Z axes) and 1mm amplitude. Vibration or impact, if less than the specified value, applied for a long time may make the mechanism loose or cause poor contact to the connectors. Especially when impact is imposed repeatedly, caution must be taken as the part pins are likely to break.

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 for inverter enclosure

From the enclosure that contains the inverter, the heat of the inverter and other equipment (transformers, lamps, resistors, etc.) and the incoming heat such as direct sunlight must be dissipated to keep the in-enclosure temperature 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 heat sink (Aluminum fin, etc.)

3) Cooling by ventilation (Forced ventilation type, pipe ventilation type)

4) Cooling by heat exchanger or cooler (Heat pipe, cooler, etc.)

REMARKS

• For replacing the cooling fan of the FR-F740P-185K or higher, 30cm of space is necessary in front of the inverter. Refer to page 336 for fan replacement.

(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 above the inverter should be heat resistant.

(5) Arrangement of multiple inverters

When multiple inverters are placed in the same enclosure, generally arrange them horizontally as shown in the right figure (a). When it is inevitable to arrange them vertically to minimize space, take such

Inverter

measures as to provide guides since heat from the bottom inverters can increase the temperatures in the top inverters, causing inverter failures.

When mounting multiple inverters, fully take caution not to make the surrounding air temperature of the inverter higher than the permissible value by providing ventilation and increasing the enclosure

(a) Horizontal arrangement

size.

(6) Placement of ventilation fan and inverter

Heat generated in the inverter is blown up from the bottom of the unit as warm air by the cooling fan. When installing a ventilation fan for that heat, determine the place of ventilation fan installation after fully considering an air flow. (Air passes through areas of low resistance. Make an airway and airflow plates to expose the inverter to cool air.)

2.1.2 EMC filter

This inverter is equipped with a built-in EMC filter (capacitive filter) and common mode choke. The EMC filter is effective for reduction of air-propagated noise on the input side of the inverter. The EMC filter is factory-set to disable (OFF). To enable it, fit the EMC filter ON/OFF connector to the ON position. The input side common mode choke, built-in the 55K or lower inverter, is always valid regardless of ON/OFF of the EMC filter ON/OFF connector.
