CAUTION: Fasten the screws with the specified fastening torque in the
table below. Check for any loosening of screws. Otherwise, there is the
danger of fire.

CAUTION: Remarks for using ground fault interrupter breakers i n the main
power supply: Adjustable frequency inverters with CE-filters (RFI-filter)
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 interrupter breakers. 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
interrupter breakers with higher trigger current. • Other components should
be secured with separate ground fault interrupter breakers. • Ground fault
interrupter breakers in the power input wiring of an inverter are not an
absolute protection against electric shock.

CAUTION: Be sure to install a fuse in each phase of the main po we r supply
to the inverter. Otherwise, there is the danger of fire.

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.

CAUTION: Failure to remove all vent opening covers before electrical
operation may result in damage to the inverter.

Powerup Test Caution Messages

CAUTION: The heat sink fins will have a high temperature. Be careful not
to touch them. Otherwise, there is the danger of getting burned.

CAUTION: The operation of the inverter can be easily changed from low
speed to high speed. Be sure to check the capability and limitations of the
motor and machine before operating the inverter. Otherwise, there is the
danger of injury.

CAUTION: If you operate a motor at a frequency higher than the inverter
standard default setting (50Hz/60Hz), be sure to check the motor and
machine specifications with the respective manufacturer. Only operate the
motor at elevated frequencies after getting their approval. Otherwise, there
is the danger of equipment damage and/or injury to personnel.

CAUTION: Check the following before and during the powerup test. Other­wise, there is the danger of equipment damage. • Is the shorting bar between
the [P] and [PD] terminals installed? DO NOT power or operate the in verter
if the jumper is removed. • Is the direction of the motor rotation correct? •
Did the inv erter trip during acce leration or deceleration? • Were the rpm and
frequency meter readings as expected? • Were there any abnormal motor
vibrations or noise?

WARNING: Be sure to turn ON the input power supply only after closing
the front case. While the inverter is energized, be sure not to open the front
case. Otherwise, there is the danger of electric shock.

WARNING: Be sure not to operate electrical equipment with wet hands.
Otherwise, there is the danger of electric shock.

WARNING: While the inverter is energized, be sure not to touch the
inverter terminals even when the motor is stopped. Otherwise, there is the
danger of electric shock.

WARNING: If the Retry Mode is selected, the motor may suddenly restart
after a trip stop. Be sure to stop the inverter before approaching the machine
(be sure to design the machine so that safety for personnel is secure even if
it restarts.) Otherwise, it may cause injury to personnel.

WARNING: If the power supply is cut OFF for a short period of time, the
inverter may restart operation after the power supply recovers if the Run
command is active. If a restart may pose danger to personnel, so be sure to
use a lock-out circuit so that it will not restart after power recovery. Other­wise, it may cause injury to personnel.

WARNING: The Stop Key is effective only when the Stop function is
enabled. Be sure to enable the Stop Key separately from the emergency
stop. Otherwise, it may cause injury to personnel.

WARNING: During a trip event, if the alarm reset is applied and the Run
command is present, the inverter will automatically restart. Be sure to apply
the alarm reset only after verifying the Run command is OFF. Otherwise, it
may cause injury to personnel.

WARNING: Be sure not to touch the inside of the energized inverter or to
put any conductive object into it. Otherwise, there is a danger of electric
shock and/or fire.

WARNING: If power is turned ON when the Run command is already
active, the motor will automatically start and injury may result. Before
turning ON the power, confirm that the RUN command is not present.

WARNING: When the Stop key function is disabled, pressing the Stop key
does not stop the inverter, nor will it reset a trip alarm.

WARNING: Be sure to provide a separate, hard-wired emergency stop
switch when the application warrants it.

WARNING: If the power is turned ON and the Run command is already
active, the motor starts rotati on and is dangerous! Before turning power ON,
confirm that the external Run command is not active.

WARNING: After the Reset command is given and the alarm reset occurs,
the motor will restart suddenly if the Run command is already active. Be
sure to set the alarm reset after verifying that the Run command is OFF to
prevent injury to personnel.

WARNING: You may need to disconnect the load from the motor before
performing auto-tuning. The inverter runs the motor forward and backward
for several seconds without regard to load movement limits.

When there has been a sudden power failure while a Run command 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 on the power
supply side, so that the circuit does not allow automatic restarting after the power supply recov­ers. If an optional remote operator is used and the retry function has been selected, this will also
allow automatic restarting when a Run command is active. So, please be careful.

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 inverter.

CAUTION: MOTOR TERMINAL VOLTAGE SURGE SUPPRESSION FILTER
(For 400 V CLASS Inverters)

In a system using an inverter with the voltage control PWM system, a voltage surge 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 terminals. A
dedicated filter of the 400 V class for suppressing this voltage surge is available. Be sure to
install a filter in this situation. (See “LCR filter” on page 5–2, part type HRL–xxxC.)

CAUTION: EFFECTS OF POWER DISTRIBUTION SYSTEMS ON INVERTERS

In the cases 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 500 kVA 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 lightning
strike are possible, install a lightning conductor.

xi

CAUTION: EFFECTS OF SHARING POWER SOURCE BETWEEN INVERTER AND
OTHER MOTORS

An electric cooling fan for the motor shall be powered from another system. A motor directly
connected to the power source shall also be power from another system. If they are powered
from the same system as the inverter, an insufficient voltage protection error (E09)or an instan­taneous power failure protection error (E16) may occur when the inverter is turned OFF.

CAUTION: Do not install inv ert ers in a corner-grounded Delta distribution system. The result­ing line imbalance will cause premature line fuse failure and failure of the inverter input bridge
rectifier. Install in a balanced Delta or Wye distribution system only.

CAUTION: When the EEPROM error E8 occurs, be sure to confirm the setting values again.

CAUTION: When using normally closed active state settings (C011 to C019) 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.

CAUTION: Do not discard the inverter with household waste. Contact an
industrial waste management company in your area who can treat industrial
waste without polluting the environment.

General Caution

CAUTION: In all the illustrations in this manual, covers and safety devices are occasionally
removed to describe the details. While operating the product, make sure that the covers and
safety devices are placed as they were specified originally and operate it according to the
instruction manual.

Digital Operator Interface Components

The SJ7002 Series inverters have a detachable keypad (called a digital operator) on the front
panel of the housing. The particular keypad that comes with the inverter depends on the country
or continent corresponding to the particular model number. The standard digital operators
occupy just part of the keypad recess in the panel. Therefore, the inverter comes with a snap-in
panel filler plate that mounts below the keypad as shown.

These detachable keypads can be mounted in a NEMA cabinet panel door cut-out, for example.
Threaded metal inserts on the rear of the keypads facilitate this external mounting configura­tion. A short cable then connects the keypad unit to the connector in the inverter keypad recess.
See Chapter 3 for information on how to install and use these keypads and cables.

Getting Started

Digital Operator OPE-SRE

standard for -LFU and -HFU models

The digital operator / copy unit is optional, and
occupies the entire keypad recess when mounted. It
has the additional capability of reading (uploading)
the parameter settings in the in verter into its memory .
Then you can install the copy unit on another inverter
and write (download) the parameter settings into that
inverter. OEMs will find this unit particularly useful,
as one can use a single copy unit to transfer parame­ter settings from one inverter to many.

Other digital operator interfaces may be available
from your Hitachi distributor for particular industries
or international markets. Contact your Hitachi
distributor for further details.

Footnotes for the preceding tables and the table that follows:

Note 1: The protection method conforms to JEM 1030.
Note 2: The applicable motor refers to Hitachi standard 3-phase motor (4-pole). When using

other motors, care must be taken to prevent the rated motor current (50/60 Hz) from
exceeding the rated output current of the inverter.

Note 3: 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.

Note 4: To operate the motor beyond 50/60 Hz, consult the motor manufacturer for the

maximum allowable rotation speed.

Note 5: When SLV is selected, please set the carrier frequency higher than 2.1 kHz.
Note 6: At the rated voltage when using a Hitachi standard 3-phase, 4-pole motor (when

selecting sensorless vector control—SLV).

Note 7: The braking torque via capacitive feedback is the average deceleration torque at the

shortest deceleration (stopping from 50/60 Hz as indicated). It is not continuous
regenerative braking torque. The average decel torque varies with motor loss. This
value decreases when operating beyond 50 Hz. If a large regenerative torque is
required, the optional regenerative braking resistor should be used.

Note 8: The frequency command will equal the maximum frequency at 9.8V for input voltage

0 to 10 VDC, or at 19.6 mA for input current 4 to 20 mA. If this characteristic is not
satisfactory for your application, contact your Hitachi sales representative.

Note 9: The storage temperature refers to the short-term temperature during transport.
Note 10: Conforms to the test method specified in JIS C0050 (1999). For the model types

excluded in the standard specifications, contact your Hitachi sales representative.

Note 11: NEMA 1 applies up to 22kW. An optional wire-entry conduit box is required for

0.4kW to 55kW models to meet NEMA 1 rating.
