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
