Check the following before turning on the power.
•Make sure that an appropriate power supply voltage is supplied and that the power input
terminals (R/L1, S/L2, and T/L3) are wired correctly.
3G3JX-A2 : 3-phase 200 to 240 V AC
3G3JX-AE : 1/3-phase 200 to 240 V AC
(Connect to L1 and N/L3 for 1 phase)
3G3JX-A4 : 3-phase 380 to 480 V AC
•Make sure that the motor output terminals (U/T1, V/T2, and W/T3) are connected to the
motor correctly.
•Make sure that the control circuit terminals and the control device are wired correctly
and that all control terminals are turned off.
•Set the motor to no-load status (i.e., not connected to the mechanical system).
•After checking the above, turn on the power.
Make sure that there are no faults in the Inverter.

•If an error occurs, the error code is displayed on the data display. In this case, refer to
"Chapter 5 Maintenance Operations" and make the necessary changes to remedy.
•Set parameter No. b084 to "02", and press the
keys simultaneously.
Set the parameters required for a test run.
•Set the motor capacity selection (H003) and the motor pole number selection (H004).
Start the no-load motor via the Digital Operator.
•Use the FREQ adjuster on the Digital Operator to rotate the motor.
Connect the mechanical system and operate via the Digital Operator.
•If there is no problem with the no-load operation, connect the mechanical system to the
motor and operate via the Digital Operator.
