Instructions on wiring
WARNING
• Connect the inverter to power via a line-protection molded-case circuit breaker or Fuse,
as fire may result.
• Always connect a ground wire, as electric shock or fire may result.
• A licensed specialist must perform the wiring works, as electric shock may result.
• Turn off the power before starting the wiring work, as electric shock may result.
• Wire the inverter after installation is complete, as electric shock or injury may occur.
CAUTION
• Confirm that the phases and rated voltage of this product match those of the AC power supply,
as injury may result.
• Do not connect the AC power supply to the output terminals (U,V,and W), as injury may result.
• Do not connect a braking resistor directly to the DC terminals (P(+)and N(-)), as fire may result.
• Ensure that the noise generated by the inverter, motor, or wiring does not adversely affect peripheral
sensors and equipment, as accident may result.
Instructions on operation
WARNING
• Be sure to install the surface cover before turning on the power (closed). Do not remove the cover while
power to the inverter is turned on.
Electric shock may occur.
• Do not operate switches with wet hands, as electric shock may result.
• When the retry function is selected, the inverter may restart automatically after tripping.
(Design the machine to ensure personal safety in the event of restart)
Accident may result.
• When the torque limiting function is selected, operating conditions may differ from preset conditions
(acceleration/deceleration time or speed). In this case, personal safety must be assured.
Accident may result.
• As the STOP key is effective only when a function setting has been established, install an emergency
switch independently, and when an operation via the external signal terminal is selected,
the STOP key on the keypad panel will be disabled.
Accident may result.
• As operations start suddenly if alarm is reset with a running signal input, confirm that no running signal
is input before resetting alarm.
Accident may result.
• Do not touch inverter terminals when energized even if inverter has stopped.
Electric shock may result.
CAUTION
• Do not start or stop the inverter using the main circuit power.
Failure may result.
• Do not touch the heat sink or braking resistor because they become very hot.
Burns may result.
• As the inverter can set high speed operation easily, carefully check the performance of motor or machine
before changing speed settings.
Injury may result.
• Do not use the inverter braking function for mechanical holding.
Injury may result.
