This instruction manual (basic) provides handling information and precautions for
use of the equipment.
Please forward this instruction manual (basic) to the end user.
This instruction manual uses the International System of Units (SI). The
measuring units in the yard and pound system are indicated in parentheses as
reference values.
This section is specifically about safety matters
Do not attempt to install, operate, maintain or inspect the inverter until you have
read through this instruction manual (basic) and appended documents carefully
and can use the equipment correctly. Do not use the inverter until you have a
full knowledge of the equipment, safety information and instructions.
In this instruction manual (basic), the safety instruction levels are classified into
"WARNING" and "CAUTION".
WARNING Assumes that incorrect handling may cause hazardous
conditions, resulting in death or severe injury.
CAUTION Assumes that incorrect handling may cause hazardous
conditions, resulting in medium or slight injury, or may
cause physical damage only.
Note that even the CAUTION level may lead to a serious consequence
according to conditions. Please follow the instructions of both levels because
they are important to personnel safety.
1. Electric Shock Prevention WARNING
!While power is on or when the inverter is running, do not open the front
cover. You may get an electric shock.
!Do not run the inverter with the front cover removed. Otherwise, you may
access the exposed high-voltage terminals or the charging part of the
circuitry and get an electric shock.
!If power is off, do not remove the front cover except for wiring or periodic
inspection. You may access the charged inverter circuits and get an electric
shock.
!Before starting wiring or inspection, check for residual voltages with a meter
etc. more than 10 minutes after power-off.
!Earth the inverter.
!Any person who is involved in the wiring or inspection of this equipment
should be fully competent to do the work.
!Always install the inverter before wiring. Otherwise, you may get an electric
shock or be injured.
!Perform setting dial and key operations with dry hands to prevent an electric
shock.
!Do not subject the cables to scratches, excessive stress, heavy loads or
pinching. Otherwise, you may get an electric shock.
!Do not change the cooling fan while power is on.
It is dangerous to change the cooling fan while power is on.
!When you have removed the front cover, do not touch the connector above
the 3-digit monitor LED display. Doing so can cause an electric shock.

2. Fire Prevention CAUTION
!Mount the inverter to incombustible material. Mounting it to or near
combustible material can cause a fire.
!If the inverter has become faulty, switch off the inverter power. A continuous
flow of large current could cause a fire.
!Do not connect a resistor directly to the DC terminals P(+), N(−). This could
cause a fire.
3. Injury Prevention CAUTION
!Apply only the voltage specified in the instruction manual to each terminal to
prevent damage etc.
!Ensure that the cables are connected to the correct terminals. Otherwise,
damage etc. may occur.
!Always make sure that polarity is correct to prevent damage etc.
!While power is on and for some time after power-off, do not touch the inverter
or brake resistor as they are hot and you may get burnt.
4. Additional instructions
Also note the following points to prevent an accidental failure, injury, electric
shock, etc.
(1) Transportation and installation CAUTION
!When carrying products, use correct lifting gear to prevent injury.
!Do not stack the inverter boxes higher than the number recommended.
!Ensure that installation position and material can withstand the weight of the
inverter. Install according to the information in the Instruction Manual.
!Do not operate if the inverter is damaged or has parts missing.
!When carrying the inverter, do not hold it by the front cover or setting dial; it
may fall off or fail.
!Do not stand or rest heavy objects on the inverter.
!Check the inverter mounting orientation is correct.
!Prevent screws, wire fragments, other conductive bodies, oil or other
flammable substances from entering the inverter.
!Do not drop the inverter, or subject it to impact.

CAUTION
!Use the inverter under the following environmental conditions:
Ambient
temperature -10°C to + 50°C (14°F to 122°F) (non-freezing)
Ambient humidity 90%RH or less (non-condensing)
Storage
temperature -20°C to +65°C (-4°F to 149°F) *
Ambience Indoors (free from corrosive gas, flammable gas,
oil mist, dust and dirt)
Environment
Altitude,
vibration
Maximum 1000m (3280.80feet) above sea level
for standard operation. After that derate by 3% for
every extra 500m (1640.40feet) up to 2500m
(8202.00feet) (91%).
5.9m/s2or less (conforming to JIS C0911)
*Temperatures applicable for a short time, e.g. in transit.
(2) Wiring CAUTION
!Do not fit capacitive equipment such as power factor correction capacitor,
radio noise filter or surge suppressor to the output of the inverter.
!The connection orientation of the output cables U, V, W to the motor will
affect the direction of rotation of the motor.
(3) Trial run CAUTION
!Check all parameters, and ensure that the machine will not be damaged by a
sudden start-up.
(4) Operation WARNING
!When you have chosen the retry function, stay away from the equipment as it
will restart suddenly after an alarm stop.
!The [STOP] key is valid only when the appropriate function setting has been
made. Prepare an emergency stop switch separately.
!Make sure that the start signal is off before resetting the inverter alarm. A
failure to do so may restart the motor suddenly.
!The load used should be a three-phase induction motor only. Connection of
any other electrical equipment to the inverter output may damage the
equipment.
!Do not modify the equipment.

A - 4
CAUTION
!The electronic overcurrent protection does not guarantee protection of the
motor from overheating.
!Do not use a magnetic contactor on the inverter input for frequent
starting/stopping of the inverter.
!Use a noise filter to reduce the effect of electromagnetic interference.
Otherwise nearby electronic equipment may be affected.
!Take measures to suppress harmonics. Otherwise power harmonics from the
inverter may heat/damage the power capacitor and generator.
!When parameter clear or all clear is performed, each parameter returns to
the factory setting. Re-set the required parameters before starting operation.
!The inverter can be easily set for high-speed operation. Before changing its
setting, fully examine the performances of the motor and machine.
!In addition to the inverter's holding function, install a holding device to ensure
safety.
!Before running an inverter which had been stored for a long period, always
perform inspection and test operation.
(5) Emergency stop CAUTION
!Provide a safety backup such as an emergency brake which will prevent the
machine and equipment from hazardous conditions if the inverter fails.
(6) Maintenance, inspection and parts replacement
CAUTION
!Do not carry out a megger (insulation resistance) test on the control circuit of
the inverter.
(7) Disposing of the inverter CAUTION
!Treat as industrial waste.
(8) General instructions
Many of the diagrams and drawings in this instruction manual (basic) show the
inverter without a cover, or partially open. Never run the inverter in this status.
Always replace the cover and follow this instruction manual (basic) when
operating the inverter.
