Pump Wiring Instructions

POWER AND SENSOR CORD, LEAD IDENTIFICATION

ZEPA0039E

 Installation and checking of electrical circuits and hardware should be performed by a qualified licensed electrician.

  “Risk of electrical shock”  

Do not remove power supply cord and strain relief.

    

           Power cords, sensor cords, and float cords all must be sealed to prevent gases from the basin entering the control panel.

INSTRUCTIONS FOR CHECKING ROTATION OF THREE PHASE UNITS

It is very important that these units be connected for proper rotation.  Since no rotating parts are visible without removing the pump from the pit, 

the rotation on 3 phase units should be checked before installation into the pit as follows:

After the proper electrical connections are made, momentarily energize the pump observing the direction of kick back due to starting torque. The rotation is 

correct if the kick back is in the opposite direction of the rotation arrow. If the rotation is not correct, disconnect power and switch any two power leads. Turn 

power back on and retest for proper rotation.

SENSOR CABLE

  The sensor cable is the smaller cable, which contains 5 wires. The red and orange wires connect to the thermal cut-out circuit and the black and white wires 

connect to the seal leak probes. The green wire is a ground connection. All 5 wires must terminate in the control panel.

The following should be noted:

(1)  The thermal sensors are normally closed and mounted adjacent to the motor windings. If internal temperatures exceed a maximum limit, the pump will 

deactivate when the red and orange wires are connected in series to the control coil of the motor starter circuit. The pump is able to restart once the motor 

cools down. Continued deactivation of this circuit requires the attention from maintenance personnel.

(2)  The black and white seal leak wires are connected to a 330K ohm circuit in the seal cavity, where 2 seal leak probes are housed.

 

An indicator light will 

activate whenever water is present in the cavity. Whenever the seal leak light is activated, indicating that the lower seal has failed, the pump should be 

removed and serviced in order to avoid damage to the motor.

(3)  The green wire shall be connected to a ground lug in the panel. 

CONTROL PANELS

These pumps require a control panel. The control panel rarely requires an explosion proof rating since it is usually located outside the hazardous area. A motor 

starter circuit, control circuit, and alarm circuit within the panel are standard features. Outdoor enclosure ratings and alternating relays are often required. Vari-

able level float switches are the most common level sensing device.

The following should be noted:

(1)  Float switch connections must be intrinsically safe.  

(2)  Single phase units have externally mounted capacitors and starting relays. Your control panel should have provisions for mounting these starting compo-

nents.  

(3)  The seal failure sensor and thermal sensor protection shall be incorporated into the panel.  

(4)  All pumps require overload protection in panel. 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.

(5)  Hazardous Location pumps require panels that offer intrinsically safe relays and all other NEC requirements must be followed (See Article 500,501, 502 

& 503 plus any others that apply.)
