Single Phase Motor Connection
The pump is configured for low voltage, 100 VAC to 115 VAC, or for high voltage, 200 VAC to 230 VAC. Low voltage
exists between connection points "4" and "Line 2" whether the pump motor is configured for low or high voltage. Figure 4
shows the electrical connections for a single phase motor.
