NOTE : POLLUTION DEGREE 2

The inverter must be used in environment of the degree 2.

Typical constructions that reduce the possibility of conductive pollution are;

1)The use of an un-ventilated enclosure

2)The use of a filtered ventilated enclosure when the ventilation is fan forced that is, ventilation is accomplished by one or more blowers within the enclosure that provide a positive intake and exhaust.

NOTE : ENCLOSURE SIZE FOR 75 kW TO 110 kW

The inverter, 75kW to 110kW must be installed into an enclosure with dimmensions no less than 183cm (72 in) by 183cm (72 in) by 60cm (24 in).

NOTE : ENCLOSURE SIZE FOR 132 kW AND BIGGER

The inverters, 132kW and bigger, are complied as recognizedcomponents.

Therse devices are intended for use in an overall ecclosure with an internal ambient of

40 degree C for variable torque rating or 50 degree C for constant torque rating maximum. End product temperature testing should be conducted to verify sufficient forced air ventilation is provided to maintain this ambient in room ambient of 10-40 degree C.

Based upon component level testing , end product temperature testing may be conducted at any convenient room ambient in the rangeof 20-40 dwgree C, unless the room ambient in the intended application exceeds 40degree C, in which case testing should be conducted at the elevated ambient.

Enclosure internal ambient temperature should be measured above the drive on to the upper left or right side. Temperature measurments on the drive itself should not be necessary.

NOTE : SET OF MOTOR CAPACITY AND POLES (A1, A2)

When data does not match a capacity of connected motor , it may cause unstaible motor operation. Set proper motor capacity (kW) and motor poles even under V/F control mode.

6.Others

WARNING

*Never modify the unit.

Otherwise, there is a danger of electric shock and/or injury.

CAUTION

*Withstand voltage tests and insulation resistance tests (megger tests) are executed before the units are shipped, so that there is no need to conduct these tests before operation.

When conducting megger tests as a part of daily inspection, be sure that these tests are only executed between the main circuit and the ground. Do not execute megger tests on the control circuit.

*Do not attach or remove wiring or connectors (including Digital operator and Remote operator) when power is applied. Also, do not check signals during operation. Otherwise, a trip may occur or a failure may be caused. To stop the operation, be sure to use an operation instruction (FW,REV.) Do not turn power off within three minutes after it is turned on, or vice versa.

*Do not stop operation by switching off the electromagnetic(Mgo) contactors on the primary or secondary sides of the inverter.To stop the operation, be sure to use an operation instruction (FW,REV.) Do not turn power off within three

minutes after it is turned on, or vice versa.

When there has been an instantaneous power failure, and if an operation instruction has been given, then the unit may restart operation after the power failure has ended. If there is a possibility that such an occurrence may harm humans, then install an electromagnetic contactor (Mgo) on the power supply side, so that the circuit does not allow automatic restarting after the power supply recovers. If the optional remote operator is used and the retry function has been selected, this will also cause automatic restarting when an operation instruction has been input, so please be careful.

*Be sure to ground the grounding terminal, .

*When inspecting the unit, after turning the power supply off be sure to wait unitl the CHARGE lamp beside the control terminal is off before opening the cover.

(If the lamp is lit or still flickering, then the internal capacitor’s residual voltage is still dangerous.)

*MOTOR TERMINAL SURGE VOLTAGE SUPPRESSION FILTER (FOR THE 400 V CLASS)

In a system using an inverter of the voltage control PWM system, a surge voltage caused by the cable constants such as the cable length (especially when the distance between the motor and inverter is 10 m or more) and cabling method may occur at the motor terminal.

A dedicated filter of the 400 V class for suppressing this surge voltage is available, Please order one.

*PROTECTION AGAINST NOISE INTERFERENCE FROM INVERTER

The inverter uses many semiconductor switching elements such as transistors and IGBTs. Thus, a radio set or measuring instrument located near the inverter is susceptible to noise interference.

To protect the instruments from erroneous operation due to noise interference, they should be installed well apart from the inverter. It is also effective to shield the whole inverter structure.

Addition of an EMI filter on the input side of the inverter also reduces the effect of noise from commercial power line on external devices.

Note that external dispersion of noise from the power line can be minimized by connecting an EMI filter on the primary side of inverter.

*EFFECTS OF DISTRIBUTOR LINES ON INVERTERS

In the cases below involving a general-purpose inverter, a large peak current flows on the power supply side, sometimes destroying the converter module. Where such situations are foreseen, or the paired equipment must be highly reliable, install an AC reactor between the power supply and the inverter.

(A)The unbalance factor of the power supply is 3% or higher.

(B)The power supply capacity is at least 10 times greater than the inverter capacity (and the power supply capacity, 500 kVA or more).

(C)Abrupt power supply changes are expected. Examples:

(1)Several inverters are interconnected with a short bus.

(2)A thyristor converter and an inverter are interconnected with a short bus.

(3)An installed phase advance capacitor opens and closes.

In cases (A), (B) or (C), we recommend installing an AC reactor of 3% (in a voltage drop at rated current) with respect to the supply voltage on the power supply side.

*When occurring an EEPROM error ( ), be sure to confirm the setting value again.

*When setting b contact to the reverse command ([REV] terminal), the inverter state automatically. Do not set to b contact.

GENERAL CAUTION

The inverters, 75kW to 110kW must be installed into an enclosure with dimmensions no less than 183cm (72 in) by 183cm (72 in) by 60cm (24 in).

NOTE : ENCLOSURE SIZE FOR 132 kW AND BIGGER

The inverters, 132kW and bigger, are complied as recognizedcomponents.

Therse devices are intended for use in an overall ecclosure with an internal ambient of

40 degree C for variable torque rating or 50 degree C for constant torque rating maximum. End product temperature testing should be conducted to verify sufficient forced air ventilation is provided to maintain this ambient in room ambient of 10-40 degree C.

Based upon component level testing , end product temperature testing may be conducted at any convenient room ambient in the rangeof 20-40 dwgree C, unless the room ambient in the intended application exceeds 40degree C, in which case testing should be conducted at the elevated ambient.

Enclosure internal ambient temperature should be measured above the drive on to the upper left or right side. Temperature measurments on the drive itself should not be necessary.

NOTE 1: The inverter should be installed in a locked enclosure that meets the requirements in IP4X.

The higher the ambient temperature inside the inverter, the shorter its life will be. If a heat generating unit is used near the inverter, try to keep it as far away as possible. Also, when installing the inverter in a box, be sure to carefully consider ventilation and the dimensions.

NOTE 2: Each of inverters 22 kW to 260 kW must be installed in a locked enclosure.

WARNING

*Be sure to ground the unit.

Otherwise, there is a danger of electric shock and/or fire.

*Wiring work shall be carried out by electrical experts. Otherwise, there is a danger of electric shock and/or fire.

*Implement wiring after checking that the power supply is off. It might incur electric shock and/or fire.

*After installing the main body, carry out wiring. Otherwise, there is a danger of electric shock and/or injury.

Power supply

*Fasten the screws with the specified fastening torque. Check so that there is no loosening of screws.

Otherwise, there is a danger of fire.

Be sure to install an earth leakage breaker.

*The ground fault protection is designed to detect current flowing to the ground upon power on. This function is to protect the inverter,not people. Install the earth leakage breaker to protect against the ground fault on wires between the inverter and the motor. (Use a breaker that is very sensitive to high frequency current so as not to cause malfunction.)

*Be sure to set the fuse(s) (the same phase as the main power supply) in the operation circuit.

Otherwise, there is a danger of fire.

As for motor leads, earth leakage breakers and electromagnetic contactors, be sure to use the equivalent ones with the specified capacity (rated).

Otherwise, there is a danger of fire.

•The inverter will be damaged if the power supply is connected to the motor terminals U(T1), V(T2) and W(T3), so be sure not to make any mistakes.

•If multiple motors are to be connected, be sure to attach a thermal relay to each motor.

NOTE 1: When changing the power supply of the motor between the inverter and commercial power, be sure to install mechanically interlocked switches Mg1 and Mg2.

NOTE 2: Install an earth leakage breaker at the input of the inverter. (Select an earth leakage breaker whose sensitive current level is raised in high frequency range.) When the cable length between the inverter and motor is long (more than 10 m), the thermal relay may malfunction due to higher harmonics. Therefore, install an AC reactor on the output side of the inverter or use a current sensor in place of the thermal relay.

300 m and less	100
600 m and less	200

NOTE 5: When using CV wire and metal tube, the leakage current is around 30 mA/km.

NOTE 6: The leakage current becomes eight times because IV wires have a high dielectric constant. Therefore, use an one class larger earth leakage breaker according to the left table.
