CAUTION: Remarks for using ground fault interrupter breakers in the main
power supply: Adjustable frequency inverter with integrated CE-filters and
shielded (screened) motor cables have a higher leakage current toward earth GND.
Especially at the moment of switching ON this can cause an inadvertent trip of
ground fault interrupters. Because of the rectifier on the input side of the inverter
there is the possibility to stall the switch-off function through small amounts of DC
current.
Please observe the following:
Use only short time-invariant and pulse current-sensitive ground fault
interrupters with higher trigger current.
Other components should be secured with separate ground fault interrupters.
Ground fault interrupters in the power input wiring of an inverter are not an
absolute protection against electric shock.
2-20
CAUTION: Be sure to install a fuse in each phase of the main power supply to the
inverter. Otherwise, there is the danger of fire.
2-20
CAUTION: For motor leads, ground fault interrupter breakers and
electromagnetic contactors, be sure to size these components properly (each must
have the capacity for rated current and voltage). Otherwise, there is the danger of
fire.

General Warnings and Cautions iv
WARNING: Never modify the unit. Otherwise, there is a danger of electric shock and/or injury.
CAUTION: Withstand voltage test and insulation resistance tests (HIPOT) are executed before
the units are shipped, so there is no need to conduct these tests before operation.
CAUTION: Do not attach or remove wiring or connectors when power is applied. Also, do not
check signals during operation.
CAUTION: Be sure to connect the grounding terminal to earth ground.
CAUTION: When inspecting the unit, be sure to wait five minutes after turning OFF the power
supply before opening the cover.
xi
CAUTION: Do not stop operation by switching OFF electromagnetic contactors on the primary
or secondary side of the inverter.
When there has been a sudden power failure while an operation instruction is active, then the
unit may restart operation automatically 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 a Run command is active. So, please be
careful.
CAUTION: Do not insert leading power factor capacitors or surge absorbers between the output
terminals of the inverter and motor.

CAUTION: EFFECTS OF POWER DISTRIBUTION SYSTEM ON INVERTER
In the case below involving a general-purpose inverter, a large peak current can flow on the
power supply side, sometimes destroying the converter module:
1. The unbalance factor of the power supply is 3% or higher.
2. the power supply capacity is at least 10 times greater than the inverter capacity (or the
power supply capacity is 500kVA or more).
3. Abrupt power supply changes are expected, due to conditions such as:
a. Several inverters are interconnected with a short bus.
b. A thyristor converter and an inverter are interconnected with a short bus.
c. An installed phase advance capacitor opens and closes.
Where these conditions exist or when the connected equipment must be highly reliable, you
MUST install an input side AC-reactor of 3% (at a voltage drop at rated current) with respect to
the supply voltage on the power supply side. Also, where the effects of an indirect lightening
strike are possible, install a lightening conductor.
CAUTION: SUPPRESSION FOR NOISE INTERFERENCE FROM INVERTER
The inverter uses many semiconductor switching elements such as transistors and IGBTs. Thus,
a radio receiver 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
used well away from the inverter. It is also effective to shield the whole inverter structure.
The addition of an EMI filter on the input side of the inverter also reduces the effect of noise
from the commercial power line on external devices.
Note that the external dispersion of noise from the power line can be minimized by connecting
an EMI filter on the primary side of the inverter.
SFEF model has integrated filter complies to EN61800-3 category C1.
HFEF model has integrated filter complies to EN61800-3 category C2.
EMI Filter
CAUTION: When the EEPROM error E08 occurs, be sure to confirm the setting values again.
CAUTION: When using normally closed active state settings (C011 to C017) for externally
commanded Forward or Reverse terminals [FW] or [RV], the inverter may start automatically
when the external system is powered OFF or disconnected from the inverter! So do not use
normally closed active state settings for Forward or Reverse terminals [FW] or [RV] unless your
system design protects against unintended motor operation.

Footnotes for the preceding table and the tables that follow:
Note1: The protection method conforms to JEM 1030.
Note2: The applicable motor refers to Hitachi standard 3-phase motor (4p). When
using other motors, care must be taken to prevent the rated motor current
(50/60Hz) from exceeding the rated output current of the inverter.
Note3: The output voltage decreases as the main supply voltage decreases (except
when using the AVR function). In any case, the output voltage cannot exceed
the input power supply voltage.
Note4: To operate the motor beyond 50/60Hz, consult the motor manufacturer for
the maximum allowable rotation speed.
Note5: For achieving approved input voltage rating categories:
460 to 480VAC – Over-voltage category 2
380 to 460VAC – Over-voltage category 3
To meet the Over-voltage category 3, insert an EN or IEC standard
compliant isolation transformer that is earth grounded and star connected
(for Low Voltage Directive).
Note6: At the rated voltage when using a Hitachi standard 3-phase, 4-pole motor.
Note7: The braking torque via capacitive feedback is the average deceleration
torque at the shortest deceleration (stopping from 50/60Hz as indicated). It is
not continuous regenerative braking torque. The average deceleration torque
varies with motor loss. This value decreases when operating beyond 50Hz. If
a large regenerative torque is required, the optional regenerative braking
unit and a resistor should be used.
Note8: The frequency command is the maximum frequency at 9.8V for input voltage
0 to 10VDC, or at 19.6mA for input current 4 to 20mA. If this characteristic
is not satisfactory for your application, contact your Hitachi representative.
Note9: If the inverter is operated outside the region shown in the graph in the
derating curve, the inverter may be damaged or its service life may be
shortened. Set Β083 Carrier Frequency Adjustment in accordance with the
expected output current level. See derating curve section for the detailed
information of the inverter operating range.
Note10: The storage temperature refers to the short-term temperature during
transportation.
Note11: Conforms to the test method specified in JIS JIS C 60068-2-6 :2010(IEC
60068-2-6:2007). For the model types excluded in the standard specifications,
contact your Hitachi sales representative.
Note12: Watt losses are calculated values based on specification of main
semi-conductors. You must take suitable margin when designing cabinet
based on these values. Otherwise there is a possibility of heating trouble.

Derating Curves
The maximum available inverter current output is limited by the carrier frequency and
ambient temperature.. Choosing a higher carrier frequency tends to decrease audible
noise, but it also increases the internal heating of the inverter, thus decreasing
(derating) the maximum current output capability. Ambient temperature is the
temperature just outside the inverter housingsuch as inside the control cabinet
where the inverter is mounted. A higher ambient temperature decreases (derates) the
inverter’s maximum current output capacity.
Individual mounting
An inverter may be mounted individually
in an enclosure or side-by-side with other
inverter(s) as shown below. Side-by-side
mounting causes greater derating than
mounting inverters separately. Graphs for
either mounting methods are included in
this section. Refer to “Ensure Adequate
Ventilation” on page 2-10 for minimum
clearance dimensions for both mounting
configurations.
