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 section is specifically about safety matters
Do not attempt to install, operate, maintain or inspect the
inverter until you have read through the Instruction Manual
(Basic) and appended documents carefully and can use the
equipment correctly. Do not use this product 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
CAUTION
Incorrect handling may cause
hazardous conditions, resulting in
death or severe injury.
Incorrect handling may cause
hazardous conditions, resulting in
medium or slight injury, or may cause
only material damage.
2. Fire Prevention
CAUTION
z Inverter must be installed on a nonflammable wall without
holes (so that nobody touches the inverter heatsink on the
rear side, etc.). Mounting it to or near flammable material
can cause a fire.
z If the inverter has become faulty, the inverter power must
be switched OFF. A continuous flow of large current could
cause a fire.
z
When using a brake resistor, a sequence that will turn OFF
power when a fault signal is output must be configured.
Otherwise the brake resistor may overheat due to damage
of the brake transistor and possibly cause a fire.
z Do not connect a resistor directly to the DC terminals P/+
and N/-. Doing so could cause a fire.
3.Injury Prevention
CAUTION
CAUTION
The level may even lead to a serious
consequence according to conditions. Both instruction
levels must be followed because these are important to
personal safety.
1. Electric Shock Prevention
WARNING
z While power is ON or when the inverter is running, do not
open the front cover. Otherwise you may get an electric
shock.
z Do not run the inverter with the front cover or wiring cover
removed. Otherwise you may access the exposed highvoltage terminals or the charging part of the circuitry and
get an electric shock.
z Even if power is OFF, do not remove the front cover
except for wiring or periodic inspection. You may
accidentally touch the charged inverter circuits and get an
electric shock.
z Before wiring or inspection, power must be switched OFF.
To confirm that, LED indication of the operation panel
must be checked. (It must be OFF.) Any person who is
involved in wiring or inspection shall wait for at least 10
minutes after the power supply has been switched OFF
and check that there are no residual voltage using a tester
or the like. The capacitor is charged with high voltage for
some time after power OFF, and it is dangerous.
z
This inverter must be earthed (grounded). Earthing
(grounding) must conform to the requirements of national
and local safety regulations and electrical code (NEC section
250, IEC 536 class 1 and other applicable standards).
A neutral-point earthed (grounded) power supply for 400V
class inverter in compliance with EN standard must be used.
z Any person who is involved in wiring or inspection of this
equipment shall be fully competent to do the work.
z The inverter must be installed before wiring. Otherwise
you may get an electric shock or be injured.
z Setting dial and key operations must be performed with
dry hands to prevent an electric shock. Otherwise you
may get an electric shock.
z Do not subject the cables to scratches, excessive stress,
heavy loads or pinching. Otherwise you may get an
electric shock.
z Do not change the cooling fan while power is ON. It is
dangerous to change the cooling fan while power is ON.
z Do not touch the printed circuit board or handle the cables
with wet hands. Otherwise you may get an electric shock.
z When measuring the main circuit capacitor capacity, the
DC voltage is applied to the motor for 1s at powering OFF.
Never touch the motor terminal, etc. right after powering
OFF to prevent an electric shock.
z The voltage applied to each terminal must be the ones
specified in the Instruction Manual. Otherwise burst,
damage, etc. may occur.
z The cables must be connected to the correct terminals.
Otherwise burst, damage, etc. may occur.
z Polarity must be correct. Otherwise burst, damage, etc.
may occur.
z While power is ON or for some time after power-OFF, do
not touch the inverter since the inverter will be extremely
hot. Doing so can cause burns.
4. Additional Instructions
Also the following points must be noted to prevent an
accidental failure, injury, electric shock, etc.
(1) Transportation and Mounting
CAUTION
z The product must be transported in correct method that
corresponds to the weight. Failure to do so may lead to
injuries.
z Do not stack the boxes containing inverters higher than
the number recommended.
z The product must be installed to the position where
withstands the weight of the product according to the
information in the Instruction Manual.
z Do not install or operate the inverter if it is damaged or
has parts missing.
z When carrying the inverter, do not hold it by the front
cover or setting dial; it may fall off or fail.
z Do not stand or rest heavy objects on the product.
z The inverter mounting orientation must be correct.
z Foreign conductive objects must be prevented from
entering the inverter. That includes screws and metal
fragments or other flammable substance such as oil.
z As the inverter is a precision instrument, do not drop or
subject it to impact.
z The inverter must be used under the following
environment: Otherwise the inverter may be damaged.

(2) Wiring
CAUTION
z Do not install a power factor correction capacitor or surge
suppressor/capacitor type filter on the inverter output
side. These devices on the inverter output side may be
overheated or burn out.
z The connection orientation of the output cables U, V, W to
the motor affects the rotation direction of the motor.
(3) Trial run
CAUTION
z Before starting operation, each parameter must be
confirmed and adjusted. A failure to do so may cause
some machines to make unexpected motions.
(4) Usage
WARNING
z Any person must stay away from the equipment when the
retry function is set as it will restart suddenly after trip.
z
Since pressing key may not stop output depending
on the function setting status, separate circuit and switch
that make an emergency stop (power OFF, mechanical
brake operation for emergency stop, etc.) must be provided.
z OFF status of the start signal must be confirmed before
resetting the inverter fault. Resetting inverter alarm with
the start signal ON restarts the motor suddenly.
z The inverter must be used for three-phase induction
motors.
Connection of any other electrical equipment to the
inverter output may damage the equipment.
z Do not modify the equipment.
z Do not perform parts removal which is not instructed in
this manual. Doing so may lead to fault or damage of the
product.
(5) Emergency stop
CAUTION
z A safety backup such as an emergency brake must be
provided to prevent hazardous condition to the machine
and equipment in case of inverter failure.
z When the breaker on the inverter input side trips, the
wiring must be checked for fault (short circuit), and
internal parts of the inverter for a damage, etc. The cause
of the trip must be identified and removed before turning
ON the power of the breaker.
z When any protective function is activated, appropriate
corrective action must be taken, and the inverter must be
reset before resuming operation.
(6) Maintenance, inspection and parts replacement
CAUTION
z Do not carry out a megger (insulation resistance) test on
the control circuit of the inverter. It will cause a failure.
(7) Disposal
CAUTION
z The inverter must be treated as industrial waste.
General instruction
Many of the diagrams and drawings in this Instruction
Manual (Basic) show the inverter without a cover or partially
open for explanation. Never operate the inverter in this
manner. The cover must be always reinstalled and the
instruction in this Instruction Manual (Basic) must be
followed when operating the inverter.
z The electronic thermal relay function does not guarantee
CAUTION
protection of the motor from overheating. It is
recommended to install both an external thermal and PTC
thermistor for overheat protection.
z Do not use a magnetic contactor on the inverter input for
frequent starting/stopping of the inverter. Otherwise, the
life of the inverter decreases.
z The effect of electromagnetic interference must be
reduced by using an EMC filter or by other means.
Otherwise nearby electronic equipment may be affected.
z Appropriate measures must be taken to suppress
harmonics. Otherwise power supply harmonics from the
inverter may heat/damage the power factor correction
capacitor and generator.
z When driving a 400V class motor by the inverter, the
motor must be an insulation-enhanced motor or measures
must be taken to suppress surge voltage. Surge voltage
attributable to the wiring constants may occur at the
motor terminals, deteriorating the insulation of the motor.
z
When parameter clear or all parameter clear is performed,
the required parameters must be set again before starting
operations because all parameters return to the initial value.
z The inverter can be easily set for high-speed operation.
Before changing its setting, the performances of the
motor and machine must be fully examined.
z Stop status cannot be hold by the inverter's brake
function. In addition to the inverter's brake function, a
holding device must be installed to ensure safety.
z Before running an inverter which had been stored for a
long period, inspection and test operation must be
performed.
z For prevention of damage due to static electricity, nearby
metal must be touched before touching this product to
eliminate static electricity from your body.
