C-4) Electrical Connections:
C-4.1) Power & Control Cords:
The cord assembly mounted to the pump must not be modified
in any way except for shortening to a specific application.
Any splice between the pump and the control panel must be
made in accordance with all applicable electric codes. It is
recommended that a junction box, if used, be mounted outside
the sump or be of at least Nema 4 (EEMAC-4) construction if
located within the wet well. DO NOT USE THE POWER OR
CONTROL CORDS TO LIFT PUMP. NOTE: THE WHITE
WIRE IS NOT A NEUTRAL OR GROUND LEAD. THE
BLACK, WHITE AND RED LEADS ARE POWER CARRYING
CONDUCTORS. THE GREEN LEAD IS FOR CONNECTION
TO GROUND.
C-4.2) Overload Protection :
C-4.2-1) Three Phase - The normally closed (N/C) thermal
sensor is embedded in the motor windings and will detect
excessive heat in the event an overload condition occurs. The
thermal sensor will trip when the windings become too hot and
will automatically reset itself when the pump motor cools to a
safe temperature. It is recommended that the thermal sensor
be connected in series to an alarm device to alert the operator
of an overload condition, and/or the motor starter coil to stop
the pump. In the event of an overload, the source of this
condition should be determined and rectified immediately. DO
NOT LET THE PUMP CYCLE OR RUN IF AN OVERLOAD
CONDITION OCCURS !
C-4.2-2) Single Phase - The type of in-winding overload
protector used is referred to as an inherent overheating
protector and operates on the combined effect of temperature
and current. This means that the overload protector will trip out
and shut the pump off if the windings become too hot, or the
load current passing through them becomes too high. It will
then automatically reset and start the pump up after the motor
cools to a safe temperature. In the event of an overload, the
source of this condition should be determined and rectified
immediately. DO NOT LET THE PUMP CYCLE OR RUN IF
AN OVERLOAD CONDITION OCCURS !

NOTE: Single phase pumps can be orederd with an optional
Thermal Sensor as well as the standard in winding overload
protection.
C-4.3) Moisture Sensors:
A normally open (N/O) detector is installed in the pump
seal chamber which will detect any moisture present. It is
recommended that this detector be connected in series to an
alarm device or the motor starter coil to alert the operator that
a moisture detect has occurred. In the event of a moisture
detect, check the individual moisture sensor probe leads
for continuity, (∞ resistance = no moisture ) and the junction
box/control box for moisture content. The above situations
may induce a false signal in the moisture detecting circuit. If
none of the above test prove conclusive, the pump(s) should
be pulled and the source of the failure identified and repaired.
IF A MOISTURE DETECT HAS OCCURRED SCHEDULE
MAINTENANCE AS SOON AS POSSIBLE.
If current through the temperature sensor exceeds the values
listed, an intermediate control circuit relay must be used to
reduce the current or the sensor will not work properly.
