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. Do not energize and de-energize the drive more frequently than one time each 30 minutes. If
you frequently energize and de-energize 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.
Note:
The location of terminals are different for different drive models.
A - DC bus terminal
B - Connect to the drive ground terminal.
C - Ground the motor case.
