use contrary to directions is ranked and explained as follows:

DANGER

CAUTION

Items labeled as CAUTION could be connected with core serious consequences,
depending upon the circumstances. In any case, these instr uctions are ex tremely import ant
and should be observed in all cases.

■■■■

Wiring

DANGER

●

Make sure the power is cut off before handling wiring.
Failure to do so could result in electrical shock or fire.

● Be sure to install a no-fuse breaker (NFB).
Failure to do so could resu lt in fire.

● Be sure to ground the GND terminal.
Failure to do so could result in electrical shock or fire.

● Have wiring work done by an electrician.
Failure to do so could result in electrical shock or fire.

● Be sure to install the inverter before wiring.
Failure to do so could result in electrical shock or fire.

CAUTION

● Do not connect the AC power source with the output terminals (U/L1, V/L2, W/L3).
Doing so could result in injury or fire.

● Make sure the voltage of the AC power source agrees with the rated voltage of the
inverter.
If not, it could result in injury or fire.

Operation

DANGER

● Be sure to mount the case and cover before turning the power on. Never remove
the case or cover while the inverter is receiving power.
Failure to mount or removing the case/cover could result in electric shock.

● The operator should secure the area before turning the power on or off.
Failure to do so could result in injury.

● Never operate the switches with wet hands.
Doing so could result in electric shock.

● Never touch the terminals of the inverter when it is charged with power, even when
it is not running. Doing so could result in electric shock.

● If the retry function is selected, the inverter could unexpectedly start operating
again if tripped. Do not approach the inverter in the condition.
Doing so could result in injury.

● If trip reset is carried out with the operate signal ON, the inverter could
unexpectedly start operating again. Do not approach the inverter in the condition.
Doing so could result in injury.

CAUTION

● The radiator and regenerative resistor become ve ry hot.
Touching these parts could result in skin burning injury.

● It is very easy to set speed from "low" to "high" by an inverter. Set the operating
speed so that it the motor and machine tolerance is not exceeded.
Failure to do so could result in injury.

Maintenance/inspection

DANGER

● Wait for at least 5 minutes after turning off the power to perform inspections.
Failure to do so could result in electric shock.

● Maintenance and inspection should not be performed by anyone except a
specialist.
The repairman should remove all metallic objects (watch, rings, etc.) before
performing maintenance or inspection.
Use only insulated tools when performing maintenance or inspection.
Failure to do so could resu lt in electric shock or injury.

Precautions

Note the following precautions in order to use the inverter properly.

1. Arrange for the power source capacity to be between 1.5 to 500kVA the inverter's
capacity. An excessively high peak current may flow to the power input circuit, and
damage the converter section if the wiring length is short with a power source
exceeding 500kVA, or the phase-advancing capacitor is switched on the power
source side. In this case, pr ovi de indiv idual pow er factor -enha ncing AC reactors that
match the inverter's capacity on the inverter input side.

2. Do not connect the phase- adv ancing cap acitor to th e outp ut sid e of th e inver ter. Doing
so could result in damage to the phase-advancing capacitor.

3. Do not provide a magnetic contactor between the inverter and motor. To run or turn
the motor on/off, use the RUN switch on the control panel or the control input terminal.
Avoid frequently turning the magnetic contactor, provided on the power source, on
and off.

4. Operating the motor by the inverter could increase leakage current and trip the earth
leakage breaker. In this case, use earth leakage bre akers d esig ned for high freque ncy
for this system and other systems.

5. Take the following precautions if using a built-in electronic thermal relay contained in
the inverter:

・Check the rated current of your 3-phase induction m otor, and set the appropriate

electronic thermal value.

・Use one motor for each inverter.

6. in using the inverter to dri ve multi ple m otors co nnecte d in parall el, s elect an i nv erter of
a capacity that does not exceed the total rated current of the inverter. When
calculating by total output of the motor, the inverter’s rated current may be exceeded,
depending on the type of motor.

7. The total wiring l ength betw een inv erter a nd mo tor sh ould not exceed 30 m eter s. I f th e
wiring is to be longer than this, you should provide a reactor, etc., between inverter
and motor.

8. Install the inverter securely to avoid injuries in the case of an earthquake.

9. Before running the inverter following an earthquake, check installation of the inverter
and motor and make sure they are safe to operate.

Precautions when wiring

Main circuit

(1) The inverter will be damaged if you invert the connections of the power input terminal

and motor output terminal (U/L1, V/L2 ... W/L3). Absolutely do not invert connections.
(2) Do not ground the main circuit terminal.
(3) Do not short motor output terminals (U/L1, V/L2 ... W/L3) together.
(4) The GND terminal (E) is the frame ground (FG) for the inverter.
(5) Be sure to use insulated crimp terminals for connecting to the main circuit terminals.

Control circuit

(1) Do not apply more than 24VDC, 50mA to the output terminals (O1, O2, −COM1), or

apply voltage to terminal in reverse.
(2) Input terminal configuration is shown in the following figure.

You can control by contact or by open collector output. Do not apply external voltage.

Internal circuits are as follows:

Photo coupler

Inverter internal power source
+12V

I1〜I6

GND

(3) Do not short the frequency setting power source terminal (5V) and ground for control

terminal (G).
(4) To directly drive the relay by the output terminals (O1, O2, −COM), mount a flywheel

diode (FD).
