X71 Series Three Phase Installation

Single Phase Installation (X7110 & X7111 Only)

All single phase models require start capacitor, run capacitor and relay in the circuit to start and operate properly. These components can be 

purchased separately or prewired in a Zoeller control panel. For components purchased separately use the diagram for installation and hookup.
Single phase models are nonautomatic. To operate automatically a control panel  must be added to the power circuit. Follow the instructions 

provided with the panel.

Three phase pumps are nonautomatic. To operate automatically, a 

control panel with level control is required. Follow the instructions 

provided with the panel to wire the system.

Before installing a pump, check the pump rotation to insure that 

wiring has been connected properly to power source, and that 

the green lead of power cord (See wiring diagram), is connected 

to a valid ground, Momentarily energize the pump, observing the 

directions of kick back due to starting torque. Rotation is correct if 

kick back is in the opposite direction of rotation arrow on the pump 

casing. If rotation is not correct, switching of any two power leads 

other than ground, should provide the proper rotation. 

Refer to the wiring diagram supplied with specific electrical control 

panel for correct electrical cable termination locations.

NOTE 1:

 Sensor cable includes 5 leads; 2 leads for thermal sensor, 2 leads for 

moisture sensor, and a green ground lead. Sensor wire colors are as shown.
