Electrical Connection
•
Check the pump label for proper voltage required. Do not connect to voltage other than that shown.
•
Connect to a circuit equipped with a ground fault circuit interrupter (GFCI) device if required by code.
•
The pump should be connected or wired to its own circuit with no other electric receptacles or equip
-
ment in the circuit.
•
The fuses or circuit breaker should be of ample capacity in the electrical circuit. For amperage ratings,
refer to
“3” Discharge Models” on page 3
and
“4” Discharge Models” on page 4
.
IMPORTANT:
Use with approved motor control that matches motor input in full load amperes with
overload element(s) selected or adjusted in accordance with control instructions.
•
Follow the wiring instructions supplied with the control panel. Make proper connections for the heat
sensor, seal fail sensor, level sensing equipment, and thermal and overload protection system(s).
IMPORTANT:
Improper wiring or lack of the seal fail sensor, thermal pro
-
tection system, and/or the overload protection system to the control panel
will void the warranty.
Heat Sensor Wiring
Motor heat sensors open if the motor windings experience excessive heat,
thereby opening the circuit in the control panel and cutting off power to the
pump. The pump automatically restarts when the motor has cooled to an accept
-
able temperature.
IMPORTANT:
Improper wiring of the heat sensor to the control panel will
void the warranty.
Connect the black and red heat sensor leads to the thermal sensor terminals in
the panel.
Seal Fail Sensor Wiring
The motor has integral moisture sensors that must be properly connected to a control panel with seal-fail
circuitry. The pump can be removed from service when moisture is detected in the seal-fail chamber. The
presence of water in this chamber energizes the seal leak warning light inside the control panel (if so
equipped with this option).
IMPORTANT:
Improper wiring of the seal fail sensor to the control panel will void the warranty.
NOTE:
This is a warning light only and will not keep the pump from continuing to operate.
•
Connect the white moisture sensor lead to the seal terminal in the control panel.
•
Connect the green ground wire to ground inside the control panel.
Risk of severe injury or death by electrical shock, high temperatures, or
pressurized fluids.
•
To minimize risk of electrical shock, disconnect power before working on or around the system.
•
The flexible jacketed cord assembly mounted to the pump must not be modified in any way, with the
exception of shortening the cord to fit into a control panel. Any splice between the pump and the
control panel must be made within a junction box mounted outside of the basin and comply with the
National Electrical Code. Employ a licensed electrician.
