General Precautions - Read These First!
WARNING: This equipment should be installed, adjusted, and serviced by qualified electrical
maintenance personnel familiar with the construction and operation of the equipment and the
hazards involved. Failure to observe this precaution could result in bodily injury.
WARNING: The user is responsible for ensuring that all driven machinery, drive train mecha-
nism not supplied by Hitachi Industrial Equipment Systems Co., Ltd., and process line material
are capable of safe operation at an applied frequency of 150% of the maximum selected
frequency range to the AC motor. Failure to do so can result in destruction of equipment and
injury to personnel should a single-point failure occur.
WARNING: For equipment protection, install a ground leakage type breaker with a fast
response circuit capable of handling large currents. The ground fault protection circuit is not
designed to protect against personal injury.
HIGH VOLTAGE: HAZARD OF ELECTRICAL SHOCK. DISCONNECT INCOMING
POWER BEFORE WORKING ON THIS CONTROL.
WARNING: Wait at least five (5) minutes after turning OFF the input power supply before
performing maintenance or an inspection. Otherwise, there is the danger of electric shock.
CAUTION: These instructions should be read and clearly understood before working on

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.
............. 2–16
CAUTION: Remarks for using ground fault interrupter breakers in 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 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.
............. 2–19
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.
............. 2–19
CAUTION: For motor leads, ground fault interrupter breakers and electro-
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.
............. 2–19
CAUTION: Failure to remove all vent opening covers before electrical
operation may result in damage to the inverter.
............. 2–20
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.
............. 2–21

CAUTION: The heat sink fins will have a high temperature. Be careful not
to touch them. Otherwise, there is the danger of getting burned.
............... 4–2
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.
............... 4–2
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.
............... 4–2

application exceeds the maximum current or voltage characteristics of a
connection point.
............... 4–6
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.
............. 4–29
CAUTION: When the motor runs at lower speeds, the cooling effect of the
motor’s internal fan decreases.
............. 4–47
Warnings and Cautions for Troubleshooting and Maintenance
WARNING: Wait at least five (5) minutes after turning OFF the input power
supply before performing maintenance or an inspection. Otherwise, there is
the danger of electric shock.
............... 6–2
WARNING: Make sure that only qualified personnel will perform mainte-
nance, 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.
............... 6–2
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.
............... 6–2
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.
............. 6–11
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.
............. 6–11
WARNING: The screws that retain the capacitor bank assembly are part of
the electrical circuit of the high-voltage internal DC bus. Be sure that all
power has been disconnected from the inverter, and that you have waited at
least 5 minutes before accessing the terminals or screws. Be sure the charge
lamp is extinguished. Otherwise, there is the danger of electrocution to
personnel.
............. 6–13

L300P Inverter ix
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 recov-
ers. 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: Do not operate the inverter unless you have replaced the six
screws that connect the capacitor bank assembly to the inverter’s circuits.
Otherwise, damage to the inverter may occur.
............. 6–13
CAUTION: Remove the fan assembly carefully, since it is attached to the
unit via connecting wires.
............. 6–14
HIGH VOLTAGE: Be careful not to touch wiring or connector terminals
when working with the inverters and taking measurements. Be sure to place
the measurement circuitry above in an insulated housing before using them.

CAUTION: Do not insert leading power factor capacitors or surge absorbers between the
output terminals of the inverter and motor.
CAUTION: Be sure to connect the grounding terminal to earth ground.
CAUTION: When inspecting the unit, be sure to wait five 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.

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: Do not install inverters in a corner-grounded Delta distribution system. The result-
ing 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 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.
