Powerup Test Caution Messages
CAUTION: Be sure not to connect an AC power supply to the output
terminals. Otherwise, there is the possibility of damage to the inverter
and the danger of injury and/or fire.
..... 2–21
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 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.
..... 2–21
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.
..... 2–21
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.
..... 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.

Warnings for Configuring Drive Parameters
Cautions for Configuring Drive Parameters
Warnings for Operations and Monitoring
WARNING: When parameter B012, level of electronic thermal setting, is
set to motor FLA rating (Full Load Ampere nameplate rating), the
inverter provides solid state motor overload protection at 115% of motor
FLA or equivalent. If parameter B012 exceeds the motor FLA rating, the
motor may overheat and be damaged. Parameter B012, level of electronic
thermal setting, is a variable parameter.
.... 3–34
CAUTION: Be careful to avoid specifying a braking time that is long
enough to cause motor overheating. If you use DC braking, we recom-
mend using a motor with a built-in thermistor, and wiring it to the
inverter’s thermistor input (see “Thermistor Thermal Protection” on
page 4–26). Also refer to the motor manufacturer’s specifications for
duty-cycle recommendations during DC braking.

Warnings and Cautions for Troubleshooting and Maintenance
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: 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: 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.
WARNING: Wait at least five (5) minutes after turning OFF the input
power supply before performing maintenance or an inspection. Other-
wise, there is the danger of electric shock.
...... 6–2
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.
...... 6–2
WARNING: Never remove connectors by pulling on its wire leads (wires
for cooling fan and logic P.C.board). Otherwise, there is a 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.
.... 6–10
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.
.... 6–10
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 components above in an insulated
housing before using them.
.... 6–14

x
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 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: MOTOR TERMINAL SURGE VOLTAGE SUPPRESSION FILTER
(For the 400 V CLASS)
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.

CAUTION: EFFECTS OF POWER DISTRIBUTION SYSTEM ON INVERTER
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: 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: When the EEPROM error E08 occurs, be sure to confirm the setting values
again.
CAUTION: When using normally closed active state settings (C011 to C016) for exter-
nally 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: 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.
