Checkpoints before Connecting the Power Supply
• Check that the power supply is on the correct voltage and that the motor
output terminals (R/L1, S/L2, and T/L3) are connected to the motor
correctly.
CIMR-J7AZ-2
_
: Three-phase 200 to 230 V AC
CIMR-J7AZ-B
_
: Single-phase 200 to 240 V AC (Wire R/L1 and S/L2)
CIMR-J7AZ-4
_
: 3-phase 380 to 460 V AC
• Make sure that the motor output terminals (U/T1, V/T2, and W/T3) are
connected to the motor correctly.
• Ensure that the control circuit terminals and the control device are wired
correctly. Make sure that all control terminals are turned off.
• Set the motor to no-load status (i.e., not connected to the mechanical
