Motor Connections —

1.Models MH-60, MH-6N, and MH-6L are available in either single phase or 3 phase voltages.

2.Motor rotation was set at the factory. For three phase machines, reversing the motor direction is done in the control cabinet by reversing the wires L1 and L2 on the disconnect side of the main electrical connection block. For single phase machines, motor rotation is changed at the motor connection plate on the rear of the single phase motor (If necessary).

Refer to Fig. 20 for the proper wiring of the pump motor for single and three phase voltages.
