Automatic - Plug fl oat cord into outlet, then plug pump
cord into fl oat cord.
Manual - Plug pump cord directly into outlet
C-4) Electrical Connections:
An acceptable motor control switch shall be provided at the
time of installation.
C-4.1) Power and Control Cable:
The cord assembly mounted to the pump must not be modifi ed
in any way except for shortening to a specifi c 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
cable to lift pump. NOTE: The white wire is NOT a neutral
or ground lead, but a power carrying conductor.
C-4.2) Overload Protection:
C-4.2-1) Three Phase (Optional) - 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 rectifi ed immediately.
DO
NOT LET THE PUMP CYCLE OR RUN IF AN OVERLOAD
CONDITION OCCURS !
C-4.2-2) Single Phase (Standard) - 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 rectifi ed
immediately.
DO NOT LET THE PUMP CYCLE OR RUN IF
AN OVERLOAD CONDITION OCCURS !
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.

C-4.3) Moisture Sensors - DS Models: (Optional)
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 started 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 tests prove conclusive, the pump(s) should be
pulled and the source of the failure identifi ed and repaired.
IF A MOISTURE DETECT HAS OCCURRED SCHEDULE
MAINTENANCE AS SOON AS POSSIBLE.
C-4.4) Wire Size:
Consult a qualifi ed electrician for proper wire size if additional
power cable length is required. See table for electrical
information.
SECTION: D START-UP OPERATION
D-1) Check Voltage and Phase:
Before operating pump, compare the voltage and phase
information stamped on the pump identifi cation plate to the
available power.
D-2) Check Pump Rotation:
Before putting pump into service for the fi rst time, the motor
rotation must be checked. Improper motor rotation can result
in poor pump performance and can damage the motor and/
or pump. To check the rotation, suspend the pump freely,
momentarily apply power and observe the “kickback”.
“Kickback” should always be in a counter-clockwise direction
as viewed from the top of the pump motor housing.
D-2.1) Incorrect Rotation for Three-Phase Pumps:
In the event that the rotation is incorrect for a three-phase
installation, interchange any two power cable leads at the
control box.
DO NOT change leads in the cable housing in the
motor. Recheck the “kickback” rotation again by momentarily
applying power.
D-2.2) Incorrect Rotation for Single-Phase Pumps:
In the unlikely event that the rotation is incorrect for a single
phase pump, contact a Barnes Service Center.
D-3) Start-Up Report:
Included at the end of this manual is a start-up report sheet,
this sheet is to be completed as applicable. Return one copy
to Barnes and store the second in the control panel or with
the pump manual if no control panel is used. It is important to
record this data at initial start-up since it will be useful to refer
to should servicing the pump be required in the future.
