RISK OF ELECTRIC SHOCK OR PERSONNEL INJURY
• Wait at least 5 minutes after turning OFF the power
supply before starting maintenance and inspection.
• Read the Instruction Manual carefully before operation.
• Read the Instruction Manual carefully before operation.
1.2 Special Precautions for Correct Use

• Use the inverter only within allowable ambient temperature range.(-10℃ to 50℃ )
(5.5kW/7.5kW/11kW/15kW Temperature for -10℃ to 40℃ light load specification)
Since service life of the inverter is greatly affected by ambient temperature, use it within
allowable temperature range. Also, observe the installation direction and conditions.
• The inverter will be damaged if the power voltage is applied to its output side.
Applying power voltage to the output terminal U, V or W will damage the inverter.
Check carefully for faulty wiring and operation sequence (commercial switching circuit,
etc.). Never apply a voltage exceeding the allowable range.
• Never touch the inside of inverter during operation.
Failure to do so could be extremely dangerous, since the inverter contains high-voltage
circuit. Before making an internal check, be sure to wait at least 5 minutes after turning OFF
the power supply of inverter. Do not touch heat sink or braking resistor during operation as
these parts are under high temperature.
• Radio interference
The main circuit of the inverter contains a high-frequency harmonic component and may
interfere with communicating equipment (such as AM radio) nearby. The severity of
interference depends on the radio field strength and is hard to be eliminated completely.
While it may be reduced by relocating radio antenna, using noise filter, housing the inverter
in a metal box or routing cables in conduit. (Please consult with us separately.)
• Do not conduct insulation resistance test between wires of the inverter.
To measure insulation resistance between power cord and motor wires, please remove
cables connected to the inverter and conduct test with them. Do not conduct insulation
resistance test on the control circuits. However, insulation resistance test can be performed
between charging unit and the ground.
• Do not use a magnetic contactor which is connected to power side or load side of the
inverter to start or stop the motor (inverter).
Frequent ON/OFF switching on the power supply side can cause inverter malfunction. Also,
do not conduct ON/OFF switching on load side during inverter operation, or it can cause
fault trip of the inverter. Start or stop the motor by operating signals of the inverter only.
• Do not connect a phase advance capacitor or a surge absorber to output side of the
inverter.
Such device can damage the inverter, resulting in broken of capacitors and other parts.
Remove it if connected.
• Do not use the inverter for load other than a motor or for a 1-phase motor.
• Precautions for inverter's protection function
The inverter integrates various protection functions such as stall prevention, current limiting
and overcurrent shut-off. These protection functions are functions used to protect the
inverter against the sudden abnormal conditions, instead of general control functions.
Therefore, avoid using them in applications where they will be activated under normal
4
conditions.
Failure to do so may reduce the inverter's service life or damage the inverter.
Always measure the output current, etc. with a meter, check the details of the fault trip
memory, and confirm that operation conditions conform to the precautions specified in the
Instruction Manual and specifications are correct.
When ptorection functions are enables, reset the inverter and operate it again after
troubleshooting.
In addition, if the the circuit breaker of at input side of inverter trips, it may be caused by
the wiring fault or damage of internal parts of inverter etc.
Determine the trip reason of circuit breaker and turn it ON again after troubleshooting.
• Take measures against higher harmonics.
The higher harmonics generated by inverter may cause overheating of or damage to
phase advance capacitor or generator.
• Precautions on 400V series motor
When 400V series motor is driven by the inverter, use the motor with reinforced insulation
treatment or take measures against the surge voltage.
If the surge voltage generated on motor terminals due to the connection factor, it may
cause the aging of motor insulation.
• Electronic thermal relay may not provide overheating protection for the motor. It is
recommended to set the external thermal relay and PTC thermistor for overheating
protection at the same time.

4.2 Precautions on Wiring Main Circuit
█ Precautions on wiring
To avoid mistakes in wiring and operation, be sure to observe the following guides.
(Failure to do so may damage the unit.)
· Always connect the power supply to input terminals (R/L1, S/L2, T/L3)(1-Phase
200V input terminals L1, L2), and connect the motor to output terminals (U, V, W).In
addition, connect the output terminals (U, V, W) in correct order. Otherwise the motor
will rotate reversely.
· Use round crimp terminals with sleeve for power supply and motor connections.
Select crimp terminals according to wire sizes and screw sizes.
· After wiring main circuit, confirm the tightening condition of terminals.
· Main circuit must be wired prior to control circuit. Otherwise, re-tightening operation is
not possible after control circuit wiring is completed.
· When connecting directly to a transformer of large capacity (500kVA or more), always
install an AC reactor on the input side of the inverter.
Note 1) Maximum number of terminal blocks for main circuit: 2.

Note 2) It is recommended to use teflon insulated wire (600V, Class 2, continuous
maximum allowable operating temperature up to 75℃ ) for main circuit wiring.
Note 3) Use wires with larger diameter if the wiring distance is long.
Note 4) If the overcurrent trip of the circuit breaker is magnetic type, the device could
become overheated due to higher harmonics. Use a load rate of 50% or lower
in this case.
Note 5) Do not use a circuit breaker for motor.
Note 6) Always connect protective devices against overcurrent, short-circuit and
current leakage on the input side.
15
█ Precautions on using regenerative braking
· When using regenerative braking, set the parameter P026 to "0". Since the factory
setting is "1", the braking will not work.

· Precautions on selection of braking resistor by customer himself/herself
1) Resistance (Ω)
The resistance shown in the reference table during the resistor selection can be
increased properly, but it will cause the braking torque reduced accordingly.
2) Allowable continuous power (W)
The allowable power shown in the reference table can be increased properly, but the
higher power can make the resistor generate a lot of heat (300℃ ). Please consult with
resistor manufacture, and provide protection during installation.
3) Allowable braking duty factor (%)
The higher the allowable continuous power for braking resistor is, the higher duty
factor can be used theoretically. But the internal resistor of inverter will overheat,
therefore please use duty factor of 5% shown in the reference table.

4.4 Common Precautions on Terminals for Control
Circuit
· For wiring of terminals for control circuit, strip specified length of insulation coating
before connecting.
· Loosen terminal screws and insert wires from bottom of the terminal block, and
tighten screws to specified tightening torque.
· Any loose connection could cause wire to come off and lead to malfunction. Also,
over-tightening could cause short-circuit due to broken of screws or the unit, thus
leading to malfunction.
· Use shielded cables for all control signal lines and separate them from power lines or
high-voltage circuits (20cm or more).
· Wiring length of control signal lines should be within 30m.
· Since input signals of control circuit are feeble, use dedicated contact for feeble
signals to avoid poor contact during contact input.

U Maintenance and Inspection
6.1 Safety Precautions
Wait at least five minutes after turning off the input power before
starting the maintenance and inspection work.
Failure to do so may result in electric shock.
Maintenance, inspection and part replacement work must be
done only by qualified persons.
Danger (Remove metal articles such as watch, bracelet(s) etc. before
operation.)
(Please use insulated tools.)
Failure to do so may result in electric shock or injury.
Do not replace the cooling fan when power is ON. Failure to do
so may result in electric shock
Employ an electrical engineering company to periodically
Caution tighten the terminal screws.
Loose terminal screws could lead to overheating or fire.
6.2 Precautions on Inspection

· To measure the insulation resistance between the power supply cable and the motor
cable with a megger, always disconnect the wires connected to the inverter first
before measuring. Do not make such measurement on the control circuit.
· The inverter is mainly consisted of semiconductor elements. To prevent the negative
effects arising from the temperature, humidity, dust and vibration etc. in working
environment and the malfunctions caused by components’aging and service life,
please perform daily inspection. The following table shows the standard replacement
interval (years) under normal working conditions (average annual ambient
temperature = 30℃ , load factor < 80% and average daily operation period < 12 h).
6.3 Inspection Items

1. Daily inspection:Basically check if abnormality occurs during operation. A multimeter
is normally used to check the input and output voltages of the
inverter during operation.
2. Periodic inspection:To check all locations where inspection can be performed only
when the inverter is stopped and where periodic inspection is
required.
28
6.4 Component Replacement
Wear-out faults are related to endurance period and service life. The endurance period
largely depends on the working conditions.
1. For example, service life of relay is determined by the roughness of the contact
surface. Contact current and load inductance are the major factors affecting its service
life.
2.Capacitor inside the inverter is used mainly as a smoothing filter. Due to the
chemical reaction that takes place internally, its service life is greatly affected by the
temperature. Generally speaking, rising of 10℃ in temperature reduces the service
life of an aluminum electrolytic capacitor by half, which also affects the service life of
inverter. When the inverter is used under high temperature, the aluminum electrolytic
capacitor may suffer from wear-out faults prior to other components in normal status
and must be replaced to extend the service life of inverter.
