CAUTION: Fasten the screws with the specified fastening torque in the	............. 2–20
table below. Check for any loosening of screws. Otherwise, there is the
danger of fire.
CAUTION: Remarks for using ground fault interrupter breakers in the main	............. 2–25
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 follow-
ing: • 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 power supply	............. 2–25
to the inverter. Otherwise, there is the danger of fire.
CAUTION: For motor leads, ground fault interrupter breakers and electro-	............. 2–25
magnetic 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	............. 2–26
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	............. 2–27
to touch them. Otherwise, there is the danger of getting burned.
CAUTION: The operation of the inverter can be easily changed from low	............. 2–27
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	............. 2–28
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. Other-	............. 2–28
wise, there is the danger of equipment damage. • Is the shorting bar between
the [P] and [PD] terminals installed? DO NOT power or operate the inverter

if the jumper is removed. • Is the direction of the motor rotation correct? • Did the inverter trip during acceleration or deceleration? • Were the rpm and frequency meter readings as expected? • Were there any abnormal motor vibrations or noise?

case. Otherwise, there is the danger of electric shock.
WARNING: Be sure not to operate electrical equipment with wet hands.	............... 4–3
Otherwise, there is the danger of electric shock.
WARNING: While the inverter is energized, be sure not to touch the	............... 4–3
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	............... 4–3
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	............... 4–3
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. Other-
wise, it may cause injury to personnel.
WARNING: The Stop Key is effective only when the Stop function is	............... 4–3
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	............... 4–3
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	............... 4–3
put any conductive object into it. Otherwise, there is a danger of electric
shock and/or fire.

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	............... 4–3
does not stop the inverter, nor will it reset a trip alarm.
WARNING: Be sure to provide a separate, hard-wired emergency stop	............... 4–3
switch when the application warrants it.
WARNING: If the power is turned ON and the Run command is already	............. 4–15
active, the motor starts rotation 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,	............. 4–24
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	............. 4–71
performing auto-tuning. The inverter runs the motor forward and backward
for several seconds without regard to load movement limits.

Cautions for Operations and Monitoring

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 check the capability and limitations of the motor and machine before operating the inverter. Otherwise, it may cause injury to personnel.

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.

CAUTION: It is possible to damage the inverter or other devices if your application exceeds the maximum current or voltage characteristics of a connection point.

CAUTION: Be careful not to turn PID Clear ON and reset the integrator sum when the inverter is in Run Mode (output to motor is ON). Otherwise, this could cause the motor to decelerate rapidly, resulting in a trip.

CAUTION: When the motor runs at lower speeds, the cooling effect of the motor’s internal fan decreases.

CAUTION: If the inverter capacity is more than twice the capacity of the motor in use, the inverter may not achieve its full performance specifications.

Warnings and Cautions for Troubleshooting and Maintenance

WARNING: Wait at least ten (10) minutes after turning OFF the input power supply before performing maintenance or an inspection. Otherwise, there is the danger of electric shock.

WARNING: Make sure that only qualified personnel will perform maintenance, inspection, and part replacement. Before starting to work, remove any metallic objects from your person (wristwatch, bracelet, etc.). Be sure to use tools with insulated handles. Otherwise, there is a danger of electric shock and/or injury to personnel.

WARNING: Never remove connectors by pulling on its wire leads (wires for cooling fan and logic P.C. board). Otherwise, there is danger of fire due to wire breakage and/or injury to personnel.

CAUTION: Do not connect the megger to any control circuit terminals such as intelligent I/O, analog terminals, etc. Doing so could cause damage to the inverter.

CAUTION: Never test the withstand voltage (HIPOT) on the inverter. The inverter has a surge protector between the main circuit terminals above and the chassis ground.

to personnel.
CAUTION: Do not operate the inverter unless you have replaced the two .............	6–21
screws that connect the capacitor bank assembly to the internal DC bus.
Otherwise, damage to the inverter may occur.
HIGH VOLTAGE: Be careful not to touch wiring or connector terminals .............	6–26
when working with the inverters and taking measurements. Be sure to place
the measurement circuitry above in an insulated housing before using them.

General Warnings and Cautions

WARNING: Never modify the unit. Otherwise, there is a danger of electric shock and/or injury.

CAUTION: Withstand voltage tests 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: Do not stop operation by switching OFF electromagnetic contactors on the primary or secondary sides of the inverter.

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: Be sure to connect the grounding terminal to earth ground.

CAUTION: When inspecting the unit, be sure to wait 10 minutes after tuning OFF the power supply before opening the cover.

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.

SJ7002 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.

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 inverters 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.

SJ7002 Inverter

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.

Digital Operator OPE-SRE	Digital Operator OPE-S
standard for -LFU and -HFU models	standard for -HFE 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 inverter 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.
