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.

Turn ON and OFF (Good example)
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
In all the illustrations in this manual, covers and safety devices are occasionally removed to describe the details. When the product is operated, make sure that the covers and safety devices are placed as they were specified originally and operate it according to the instruction manual.

*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.

NOTE 1: The applicable equipment is for Hitachi standard four pole squirrel-cage motor NOTE 2: Be sure to consider the capacity of the circuit breaker to be used.
NOTE 3: Be sure to use bigger wires for power lines if the distance exceeds 20m. NOTE 4: Be sure to use an grounding wire same size of power line or similar.
(*) Use AWG 16 wire for the alarm signal wire.
Classify the detective current of the earth leakage breaker depending on the total distance between the inverter and the motor.

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.
