Main Circuit Wiring
This section gives information about the functions, specifications, and procedures necessary to safely and correctly
wire the main circuit in the drive.
NOTICE: Damage to Equipment. The drive can fail if users frequently turn the drive ON and OFF with the MC on the power source
side to Run and Stop the drive. Incorrect operation can decrease the service life of the relay contacts and electrolytic capacitors. If
you frequently use the magnetic contactor on the power source side to Run and Stop the drive, it can cause drive failure.
Note:
Soldered wire connections can become loose over time and cause unsatisfactory drive performance.

Motor and Main Circuit Connections
WARNING! Electrical Shock Hazard. Do not connect terminals R/L1, S/L2, T/L3, U/T1, V/T2, W/T3, -, +1, +2, +3, B1, or B2 to the
ground terminal. If you connect these terminals to earth ground, it can cause damage to the drive or serious injury or death.
A - DC bus terminal
B - Connect to the drive ground
terminal.
C - Ground the motor case.
Note:
The location of terminals are different for different drive models.
