WARNING

 Do not remove the front cover or the wiring cover while the power of this product is ON, and do not run this product with

the front cover or the wiring cover removed as the exposed high voltage terminals or the charging part of the circuitry

can be touched. Doing so may cause an electric shock.

 Even if power is OFF, do not remove the front cover except for wiring or periodic inspection as the inside of this product

is charged. Doing so may cause an electric shock.

 Before wiring or inspection, check that the LED display of the operation panel is OFF. Any person who is involved in

wiring or inspection shall wait for 10 minutes or longer after the power supply has been cut 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.

 This product must be earthed (grounded). Earthing (grounding) must conform to the requirements of national and local

safety regulations and electrical code (NEC section 250, IEC 61140 class 1 and other applicable standards). A neutral-

point earthed (grounded) power supply must be used for 400 V class of this product to be compliant with EN standard.

 Any person who is involved in wiring or inspection of this product shall be fully competent to do the work.

 This product must be installed before wiring. Otherwise you may get an electric shock or be injured.

 Do not touch the setting dial or keys with wed hands. Doing so may cause an electric shock.

 Do not subject the cables to scratches, excessive stress, heavy loads or pinching. Doing so may cause an electric shock.

 Do not change the cooling fan while power is ON as it is dangerous.

 Do not touch the printed circuit board or handle the cables with wet hands. Doing so may cause an electric shock.

 Never touch the motor terminals, etc. right after powering OFF as the DC voltage is applied to the motor for 1 second at

powering OFF if the main circuit capacitor capacity is measured. Doing so may cause an electric shock.

 Before wiring or inspection for a PM motor, confirm that the PM motor is stopped as a PM motor is a synchronous motor

with high-performance magnets embedded inside and high-voltage is generated at the motor terminals while the motor

is running even after the power of this product is turned OFF. In an application, such as fan and blower, that the motor

may be driven by the load, connect a low-voltage manual contactor at the output side of this product and keep it open

during wiring and inspection of this product. Otherwise you may get an electric shock.

CAUTION

 This product must be installed on a nonflammable wall without any through holes so that nobody touches the heat sink,

etc. on the rear side of this product. Installing it on or near flammable material may cause a fire.

 If this product has become faulty, the product power must be switched OFF. A continuous flow of large current may cause

a fire.

 Do not connect a resistor directly to the DC terminals P/+ and N/-. Doing so could cause a fire.

 Be sure to perform daily and periodic inspections as specified in the Instruction Manual. If this product is used without

any inspection, a burst, breakage, or a fire may occur.

CAUTION

 The voltage applied to each terminal must be as specified in the Instruction Manual. Otherwise burst, damage, etc. may

occur.

 The cables must be connected to the correct terminals. Otherwise burst, damage, etc. may occur.

 The polarity (+ and -) must be correct. Otherwise burst, damage, etc. may occur.

W of this product wired to the PM motor hold high voltages all that while. Before wiring other terminals, be sure that the

PM motor is stopped. Otherwise you may get an electric shock.

 Never connect a PM motor to the commercial power supply. Applying the commercial power to the input terminals (U,

V, W) on a PM motor will burn the PM motor. The PM motor must be applied a power from this product with the output

terminals (U, V, W).

Test operation

 Before starting the test operation, confirm or adjust the parameter settings. Failure to do so may cause some machines

to make unexpected motions.

11

WARNING

Usage

 Stay away from the equipment after using the retry function in this product as the equipment will restart suddenly after

the output shutoff of this product.

 Depending on the function settings of this product, the product does not stop its output even when the STOP/RESET

key on the operation panel is pressed. To prepare for it, provide a separate circuit and switch (to turn OFF the power of

this product, or apply a mechanical brake, etc.) for an emergency stop.

 Be sure to turn OFF the start (STF/STR) signal before clearing the fault as this product will restart the motor suddenly

after a fault is cleared.

 Do not use a PM motor for an application that the motor may be driven by the load and run at a speed higher than the

maximum motor speed.

 Use only a three-phase induction motor or PM motor as a load on this product. Connection of any other electrical

equipment to the output of this product may damage the equipment.

 Do not modify this product.

 Do not remove any part which is not instructed to be removed in the Instruction Manuals. Doing so may lead to a failure

or damage of this product.

CAUTION

Usage

 The electronic thermal O/L relay function may not be enough for protection of a motor from overheating. It is

recommended to install an external thermal relay or a PTC thermistor for overheat protection.

 Do not repeatedly start or stop this product with a magnetic contactor on its input side. Doing so may shorten the life of

this product.

 Use a noise filter or other means to minimize the electromagnetic interference with other electronic equipment used

nearby this product.

 Appropriate precautions must be taken to suppress harmonics. Otherwise harmonics in power systems generated from

this product may heat/damage a power factor correction capacitor or a generator.

 To drive a 400 V class motor with this product, use an insulation-enhanced motor, or take measures to suppress surge

voltage. Otherwise surge voltage, which is attributed to the length and thickness of wire, may occur at the motor

terminals, causing the motor insulation to deteriorate.

 As all parameters return to their initial values after the Parameter clear or All parameter clear is performed, the needed

parameters for this product operation must be set again before the operation is started.

 This product can be easily set for high-speed operation. Therefore, consider all things related to the operation such as

the performance of a motor and equipment in a system before the setting change.

 This product's brake function cannot be used as a mechanical brake. Use a separate device instead.

 Perform an inspection and test operation of this product if it has been stored for a long period of time.

 To avoid damage to this product due to static electricity, static electricity in your body must be discharged before you

touch this product.

 Only one PM motor can be connected to a single unit of this product.

 A PM motor must be used under PM motor control. Do not use a synchronous motor, induction motor, or synchronous

induction motor.

 Do not connect a PM motor to this product at a setting for the induction motor control (initial setting). Do not connect an

induction motor to this product at a setting for PM motor control. Doing so will cause a failure.

 As a process of starting a PM motor, turn ON the power of this product first, and then close the contactor on the output

side of this product.

 When the emergency drive function is enabled, the operation is continued or the retry operation (automatic reset and

restart) is repeated even if a fault occurs, which may damage or burn this product and the motor. Before restarting the

normal operation after the operation using the emergency drive function, make sure that this product and the motor have

no fault.

Emergency stop

 A safety backup such as an emergency brake must be provided for devices or equipment in a system to prevent

hazardous conditions in case of failure of this product or an external device controlling this product.

 If the breaker installed on the input side of this product trips, check for wiring faults (such as short circuits) and damage

to internal parts of this product. Identify and remove the cause of the trip before resetting the tripped breaker (or before

applying the power to this product again).

 When any protective function is activated, take an appropriate corrective action before resetting this product to resume

the operation.

Maintenance, inspection and parts replacement

 Do not carry out a megger (insulation resistance) test on the control circuit of this product. Doing so will cause a failure.

Disposal

 This product must be treated as industrial waste.

General instruction

 For clarity, illustrations in this Instruction Manual may be drawn with covers or safety guards removed. Ensure all covers

and safety guards are properly installed prior to starting operation. For details on the PM motor, refer to the Instruction

Manual of the PM motor.
