Liberty Pumps LEH-Series Sewage pumps are available in a wide range of voltage and phase configurations.
Prior to connecting the pump, check the pump's nameplate to ensure it is rated to match the supply voltage. See
Fig. B, Fig. C, and Fig. D for basic pump wiring diagrams for all 1-Phase and 3-Phase configurations.
Additionally it is required that all pumps have a means incorporated into the fixed system wiring to disconnect all
supply power.
