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.

Maintenance/Inspection

●You should perform maintenance/inspection on a regular basis in order to ensure safety
and keep the inverter in good running order.

Precautions when performing maintenance/inspections

(1) The power should be turned on/off only by the person performing the task.
(2) The internal circuits of the inverter remain charged with high voltage for a short while

after power is turned off. To perform inspection, first turn off the power and then wait for
the LED display on the front panel to go off (min. 5 minutes).

(3) Do not perform insulation resistance measurement on the inverter. Doing so will

damage the inverter.
