CAUTION! 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, fully examine the performances 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

Earth (Ground)

AC reactor(FR-BAL)

DC reactor(FR-BEL)

No-fuse breaker or earth leakage circuit breaker

Power supply

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

Magnetic contactor

Do not use this magnetic contactor to start and stop the inverter. Doing so will cause the inverter life to be shorter.

Installation of reactorsThe reactors must be used when the power factor is to beimproved or the inverter is installed near a large power supplysystem (500kVA or more and wiring distance within 10m (32.81feet)).Make selection carefully.

Earth (Ground)To prevent an electric shock, always ground the motor and inverter.For reduction of induction noise from the power line of the inverter,it is recommended to wire the ground cable by returning it to the ground terminal of the inverter. (For details of noise reduction techniques, refer to the instruction manual (detailed).)

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

The inverter life is influenced by ambienttemperature. The ambient temperature should be as low as possible within the permissible range. (Refer to page 42.)

Wrong wiring might lead to inverter damage. The control signal lines must be kept fully away from the main circuit to protect them from noise. (Refer to page 5.)

Appendix 1 Instructions for Compliance with the

European Standards(The products conforming to the Low Voltage Directive carry the CE mark.)

(1) EMC Directive1) Our view of transistorized inverters for the EMC DirectiveA transistorized inverter is a component designed for installation in a control boxand for use with the other equipment to control the equipment/device. Therefore,we understand that the EMC Directive does not apply directly to transistorizedinverters. For this reason, we do not place the CE mark on the transistorizedinverters. (The CE mark is placed on inverters in accordance with the Low VoltageDirective.) The European power drive manufacturers' organization (CEMEP) alsoholds this point of view.2) ComplianceWe understand that the transistorized inverters are not covered directly by theEMC Directive. However, the EMC Directive applies to machines/equipment intowhich transistorized inverters have been incorporated, and these machines andequipment must carry the CE marks. Hence, we prepared the EuropeanStandard-compliant noise filters and the technical information "EMC InstallationGuidelines" (information number BCN-A21041-202) so that machines andequipment incorporating transistorized inverters may conform to the EMCDirective more easily.3) Outline of installation methodInstall an inverter using the following methods:* Use the inverter with an European Standard-compliant noise filter.* For wiring between the inverter and motor, use shielded cables or run them in a

metal piping and ground the cables on the inverter and motor sides with theshortest possible distance.

* Insert a line noise filter and ferrite core into the power and control lines asrequired.Full information including the European Standard-compliant noise filterspecifications are written in the technical information "EMC InstallationGuidelines" (BCN-A21041-202). Please contact your sales representative.

(2) Low Voltage Directive1) Our view of transistorized inverters for the Low Voltage Directive

Transistorized inverters are covered by the Low Voltage Directive.2) Compliance

We have self-confirmed our inverters as products compliant to the Low VoltageDirective and place the CE mark on the inverters.

3) Outline of instructions* Connect the equipment to the earth securely. Do not use an earth leakage circuit

breaker as an electric shock protector without connecting the equipment to theearth.

* Wire the earth terminal independently. (Do not connect two or more cables toone terminal.)

* Use the cable sizes on pages 7, 9 and 11 under the following conditions.• Ambient Temperature: 40°C (104°F) maximum• Wire installation: On wall without ducts or conduits

If conditions are different from above, select appropriate wire according toEN60204 ANNEX C TABLE 5.* Use the no-fuse breaker and magnetic contactor which conform to the EN or IEC

Standard.Design notice: Where residual-current-operated protective device (RCD) is used

for protection in case of direct or indirect contact, only RCD ofType B is allowed on the supply side of this Electronic Equipment(EE). Otherwise another protective measure shall be appliedsuch as separetion of the EE from the environment by double orreinforced insulation or isolation of EE and supply system by atransformer. (Extract from EN51078)

* Use the inverter under the conditions of overvoltage category II andcontamination level 2 or higher specified in IEC664.

* Use the breaker of type B (breaker which can detect both AC and DC). If not,provide double or enhanced insulation between the inverter and otherequipment, or put a transformer between the main power supply and inverter.

* On the input and output of the inverter, use cables of the type and size set forthin EN60204 Appendix C.

* The operating capacity of the relay outputs (terminal symbols A, B, C) should be30VDC, 0.3A.

* The terminals indicated as the control circuit input and output terminals on page5 are separated safely from the main circuit.

Appendix 2 Instructions for compliance with U.S. and

Canadian Electrical Codes

1. General PrecautionThe bus capacitor discharge time is 10 minutes. Before starting wiring orinspection, switch power off, wait for more than 10 minutes, and check forresidual voltage between terminal P (+) and N (-) with a meter etc., to avoidhazard of electrical shock.

2. EnvironmentBefore installation, check that the environment meets following specifications.

Ambient temperature -10°C to +50°C (14°F to 122°F) (non-freezing)Ambient humidity 90%RH or less (non-condensing)Storage temperature(Note 2)

-20°C to +65°C (-4°F to 149°F)

Ambience Indoors (No Corrosive and flammable gases, oil mist, dust and dirt.)Altitude vibration Below 1000m (3280.80feet), 5.9m/s2 or less

3. InstallationThe below types of inverter have been approved as products for use inenclosure and approval tests were conducted under the following conditions.Design the enclosure so that the ambient temperature, humidity and ambienceof the inverter will satisfy the above specifications.Branch circuit protectionFor installation in United States, branch circuit protection must be provided, inaccordance with the National Electrical Code and any applicable local codes.For installation in Canada, branch circuit protection must be provided inaccordance with the Canada Electrical Code and any applicable provincialcodes.

4. Short circuit ratingsSuitable For Use in A Circuit Capable of Delivering Not More Than 5kA rmsSymmetrical Amperes.

49

5. Motor overload protectionThese inverters provide solid state motor overload protection.Set parameter 9 using the following instructions,(Pr. 9 "electronic thermal O/L relay").

<Setting>• Set the rated current [A] of the motor.

(Normally set the rated current at 50Hz.)• Setting "0" makes the electronic overcurrent protection (motor protective

function) invalid. (The inverter's protective function is valid).• When using a Mitsubishi constant-torque motor, first set "1" in Pr. 71 to choose

the 100% continuous torque characteristic in the low-speed range. Then, setthe rated motor current in Pr. 9.

CAUTION

• When two or more motors are connected to the inverter, they cannot beprotected by the electronic overcurrent protection. Install an external thermalrelay to each motor.

• When the difference between the inverter and motor capacities is large andthe setting is small, the protective characteristics of the electronic overcurrentprotection will be deteriorated.In this cause, use an external thermal relay.

• A special motor cannot be protected by the electronic overcurrent protection.Use an external thermal relay.
