NOTES:
1. Incoming power phase rotation should be L1, L2, L3 to match inverter forward direction phase rotation U, V, W. Connection as
shown should produce clockwise direction when viewing the motor from the shaft end. Always test motor direction in both drive and
bypass modes before coupling the motor to the load.
2. In the two contactor configuration, the M3 contactor is installed and controlled by an internal rocker switch.
