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.
