7C-4) Electrical Connections:C-4.1) Power & Control Cords:The cord assembly mounted to the pump must not bemodified in any way except for shortening to a specificapplication. Any splice between the pump and the controlpanel must be made in accordance with all applicable electriccodes. It is recommended that a junction box, if used, bemounted outside the sump or be of at least Nema 4 (EEMAC-4) construction if located within the wet well. DO NOT USETHE 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 CarryingConductors. The Green Lead Is For Connection ToGround.C-4.2) Overload Protection :C-4.2-1) Three Phase - The normally closed (N/C) thermalsensor is embedded in the motor windings and will detectexcessive heat in the event an overload condition occurs.The thermal sensor will trip when the windings become toohot and will automatically reset itself when the pump motorcools to a safe temperature. It is recommended that thethermal sensor be connected in series to an alarm device toalert the operator of an overload condition, and/or the motorstarter coil to stop the pump. In the event of an overload, thesource of this condition should be determined and rectifiedimmediately. DO NOT LET THE PUMP CYCLE OR RUN IFAN OVERLOAD CONDITION OCCURS !C-4.2-2) Single Phase - The type of in-winding overloadprotector used is referred to as an inherent overheatingprotector and operates on the combined effect of temperatureand current. This means that the overload protector will tripout 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 afterthe motor cools to a safe temperature. In the event of anoverload, the source of this condition should be determinedand rectified immediately. DO NOT LET THE PUMP CYCLEOR RUN IF AN OVERLOAD CONDITION OCCURS !NOTE: Single phase pumps can be orederd with an optionalThermal Sensor as well as the standard in winding overloadprotection.C-4.3) Moisture Sensors:A normally open (N/O) detector is installed in the pumpseal chamber which will detect any moisture present. It isrecommended that this detector be connected in series to analarm device or the motor starter coil to alert the operator thata moisture detect has occurred. In the event of a moisturedetect, check the individual moisture sensor probe leads forcontinuity, ( ∞ resistance = no moisture ) and the junctionbox/control box for moisture content. The above situationsmay induce a false signal in the moisture detecting circuit. Ifnone of the above test prove conclusive, the pump(s) shouldbe pulled and the source of the failure identified and repaired.IF A MOISTURE DETECT HAS OCCURRED SCHEDULEMAINTENANCE AS SOON AS POSSIBLE.C-4.4) Wire Size:Consult a qualified electrician for proper wire size if additionalpower cable is required.

Improper motor rotation canresult in poor pump performance and can damage the motorand/or pump. To check the rotation, suspend the pumpfreely, momentarily apply power and observe the “kickback”.“Kickback” should always be in a counter-clockwise directionas 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-phaseinstallation, interchange any two power cable leads at thecontrol box. DO NOT change leads in the cable housingin the motor. Recheck the “kickback” rotation again bymomentarily applying power.D-2.2) Incorrect Rotation for Single-Phase Pumps:In the unlikely event that the rotation is incorrect for a singlephase 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 copyto Barnes and store the second in the control panel or withthe pump manual if no control panel is used. It is important torecord this data at initial start-up since it will be useful to referto should servicing the pump be required in the future.D-3.1) Identification Plate:Record the numbers from the pump identification plate onboth START-UP REPORTS provided at the end of the manualfor future reference.D-3.2) Insulation Test:Before the pump is put into service, an insulation (megger)test should be performed on the motor. The resistance values(ohms) as well as the voltage (volts) and current (amps)should be recorded on the start-up report.D-3.3) Pump-Down Test:After the pump has been properly wired and lowered into thebasin, sump or lift station, it is advisable to check the systemby filling with liquid and allowing the pump to operate throughits pumping cycle. The time needed to empty the system, orpump-down time along with the volume of water, should berecorded on the start-up report.
