Handling and Installation

IV. Handling and Installation

1. Do not use lead wires to pull, lift or handle the motor. The lead wires should be protected during storage,
handling, moving and installation of the motor.

2. Inspect the motor to determine that it is the correct HP, voltage and size for the job and that there is no
shipping damage.

3. The factory-installed water in the motor is supplied with antifreeze capable of temperatures to -5º C (23º F).
Do not install, transport or store below these temperatures. If storage is necessary below these temperatures,
drain the water from the motor.

4. After long periods of idleness and on all new installations, check the electrical resistance and megger the
motor with lead wires connected. The insulation resistance should have a value of at least 5 megohms at
installation and at least 1 megohm after running.

5. Verify motor is lled with clean water before installing. The warranty is void if this is not done. Also check
the tightness of all water lling and drain plugs, mounting bolts and cable connections.

6. Do not hammer the shaft, coupling or slinger since this may damage the thrust bearing. Check the rotation
of the motor by hand to insure that it turns freely.

7. Do not drop the bottom end of the motor in the dirt or mud since this may plug up the diaphragm opening.

8. If motor is to be installed horizontally, make sure the relief valve is at the 12 o'clock position when facing the
motor shaft (in horizontal position).

9. Check that winding coil resistance in each two phases is equal to values in Tables 1 - 4.

10. Select the proper overload relay or heaters.

11. For 50HP and 60HP models: Remove the metal sleeve attached to the midpoint of the motor and discard.

Guidelines for VFD Control

V. Guidelines For VFD Control of

CentriPro CP-Series Rewindable
Submersible Motor

Variable Frequency Drives together with submersible pumps are today often being used when water demand
varies over time. The pump will run with the VFD at a speed optimal to the actual demand, leading to possible
energy savings.

There are a wide number of different frequency drives available on the market and they often have different
characteristics. Therefore it is important to choose a VFD and other electric components that will work
satisfactory together with the motor. VFDs generate voltage peaks and if the peaks are too high and too steep
they will damage the windings in any submersible motor.

The CentriPro CP Series submersible motors can be used with Variable Frequency Drives if the following
guidelines are followed.

Frequency Limitations

You should never run the motor with the VFD on a higher frequency than the data plate on the motor states.
With a higher frequency than stated, overload and overheating problems could occur. Generally you are never

allowed to run the pump with a frequency below 30Hz. Always make sure that the ow around the motor is
enough to cool the motor at all the duty points of operation. Values for the ow can be found in the

submersible motor technical catalogue.

Ramp Up and Ramp Down Time

The ramp up time to the minimum running frequency should be set as quick as possible (maximum 1s) to ensure
the correct lubrication of the thrust bearing in the motor. The ramp down time (from the minimum running
frequency to 0 Hz) should be set as quick as possible (maximum 1s) as well.

Filters

Filters for reducing voltage peaks and steepness generated by the VFD are recommended and should be speci-

ed by the VFD manufacturer according to the below voltage peak and rise time limits.

Voltage Drop with Long Cables

The VFD should be installed as close as possible to the motor. When this is not possible a maximum of 4%
voltage drop at the motor is acceptable.

Use of VFD with CentriPro CP Series Submersible HT Motors (high temperature version)

It is always recommended the use of HT motors with VFD operation. The reason for this is that the
HT version has a higher tolerance for voltage peaks. For HT motors the voltage peaks to the pump may never

exceed 1000 Volts and the voltage rise time dV/dt should be lower than 500V/μs. If the VFD can not full this
recommendation lters between the VFD and the motor has to be used. The requirement will then be that the
VFD together with the lters does not generate higher peaks than 1000V and that the voltage rise time dV/dt
should be lower than 500V/μs. The following indications are also recommended: use of dV/dt lters in case
of motors cable length ≤ 100 and use of sine wave lters for longer cable.

10 CP-Series Submersible Motors Installation, Operation and Maintenance Manual

Guidelines for VFD Control (continued)

Use of VFD with CentriPro CP Series Submersible Standard Motor

Standard CentriPro CP Series motors can be used if it can be guaranteed that the VFD will not generate higher

voltage peaks than 690V and if voltage rise time dV/dt is lower than 500V/μs. If the VFD can not full this
recommendation lters between the VFD and the motor has to be used. The requirement will then be that the
VFD together with the lters does not generate higher peaks than 690V and that the voltage rise time dV/dt
should be lower than 500V/μs. However it is always recommended the use of sine wave lters.

Water Temperature and VFD Use

Together with VFD we recommend the usage of the High Temperature (HT version) of the motor up to 30°C
of water temperature. For higher water temperatures a derating of the motor should be made.

Derating of the motor depends on the quality of the output from the VFD. If the quality is close to the quality
of the supply without VFD then there is no special restriction regarding water temperature for VFD use. Refer
to the technical catalogue for submersible motors for water temperature limits.

End Notes

If the installation requires operation other than stated in the guidelines or if questions arise that are not covered
in the guidelines please contact Xylem Inc. customer service for guidance. The toll free number for customer
support is 1-877-833-2872.

Pre-Installation

CAUTION

VI. Pre-Installation

1. Maximum Water Temperature:
A) Standard Version: 30° C (86° F)

Must maintain ow rate of .75 fps (5 - 10 HP), 1.0 fps (15 - 30 HP), 1.75 fps (40 HP and greater). For

temperatures above 30° C (86° F), motor output must be reduced to ensure
correct cooling: maximum temperature allowed is 35° C (95° F).

B) HT Version: 45° C (113° F)

Must maintain ow rate of .75 fps (5 - 10 HP), 1.0 fps (15 - 30 HP), 1.75 fps (40 HP and greater). For

temperatures above 45° C (113° F), motor output must be reduced to ensure
correct cooling: maximum temperature allowed is 60° C (140° F).

2. PH content of the water between: 6.5–8

3. Maximum Chlorine Content: 500 PPM
Maximum Sulfuric Acid Iron Content: 15 PPM
Maximum Flourine Content: 0.8 PPM

Maximum Electric Conductivity: 118 μMHO/INCH

4. Maximum Sand Content: 50 PPM

5. Proper approved three phase overload protection. Class 10, quick trip overloads are mandatory.
See Tables 1 - 4, 9 or 10.

6. Proper fusing for motor circuit protection. See Table 5.

7. Proper Line Voltage During Running Conditions:

460V ±10%, i.e. 506 to 414 volts

230V ±10%, i.e. 253 to 207 volts at 60 cycle system at motor lead wire terminal. (Voltage drop of cable
should be considered by user.)

Combination of Voltage and Frequency Variation: ±10% (sum of absolute values of voltage and frequency).

Phase Unbalance: ±5% (3 phase)

8. Proper sizing of motor (current, thrust, voltage, etc.) and a 10 feet clearance from the bottom of the well are
required.

9. In the case of horizontal installation, the motor is to be rigidly aligned with the pump and rmly mounted to

prevent any load on the shaft and bearings and to avoid any damaging vibrations to the motor. Also, see #8
in Section IV.

10. The maximum depth of immersion for all motors is 1,150 ft (350 m).

11. The power cables shall be sized large enough so that at rated current there will be less than a 5% voltage
drop. Cables must be waterproof submersible type.

12. For 3Ø motors a balanced and properly sized transformer bank shall be provided. Improper electrical supply
(for example, phase converter, V-connection transformer, etc.) or connections will void the warranty.

13. Single phase protection is recommended for protection of the installation. Any failure due to single phasing
of the incoming voltage causing the motor to fail will void the warranty.

14. Lightning arrestors are recommended in the interest of protecting the control panel, as well as the insulation
system of the motor. Any motor failure due to lightning or other Acts of God will void the warranty.

15. Provide waterproof insulation splices between all lead wires and well cables.

16. In the event that a reduced voltage starter is used to start the motor, the following should be veried:

A. Correct quick trip ambient compensated overloads are incorporated.

B. Proper short circuit protection is utilized.

C. The torque required by the motor and pump package is attainable by this type starter.

12 CP-Series Submersible Motors Installation, Operation and Maintenance Manual

Pre-Installation (continued), Maintenance and Operation

D. The lead arrangement of the motor is acceptable with the proposed starter load connections.

E. Verify that if any time delay relays are used in switching contactors in and out, that the time settings are

not too long; this could damage the motor.

F. If a manual auto transformer starter is used, don't wait too long to go into the "Run" condition and don't

"tease" the contacts. Double check Tables 1 - 4 for correct protection.

17. Do not expose motor leads to air. Leads must be submerged for cooling.

VII. Maintenance

There are no bearings that need oil or grease. The motor, being inaccessible, should be monitored through its
electrical connections.

1. Measure and record operating current and voltage.

2. Measure and record the motor insulation resistance. Any resistance of less than 5 megohm (5,000,000) for a

new motor should be evaluated or checked further by a qualied service shop.

3. Lightning arrestors and/or surge capacitors will help prevent damage to the control box, cables and motor.

4. Single phase protection will help in preventing motor failure due to adverse incoming primary power.

5. Based on the values obtained in 1 and 2 above and the output ow rates and pressures of the pump, a

complete picture of total performance can be obtained. This can be used to determine any pump and motor
maintenance and overhauling which might be required.

6. If the motor is to be stored, protect the unit from freezing by storing in an area with a temperature
higher than -30º C (-22º F).

VIII. Operation

1. After energizing the motor, check the ow and pressure of the pump to make sure that the motor is

rotating in the correct direction. To correct a wrong rotation, switch any two of the three cable connections.
(Three phase motor only.)

2. When starting the pump for the rst time, inspect the water for sand. If sand appears, then continue to

pump until the water clears up; otherwise, sand will accumulate in the pump stages and will bind or freeze

the moving parts if water is allowed to ow back down the well.

3. During testing or checking rotation (such as "bumping" or "inching") the number of "starts" should be
limited to 3, followed by a full 15 minute cooling-off period before any additional "starts" are attempted.
Depending on the depth of the well and/or method of checking, these rotational checks or "starts" may
actually be full-edged starts. If this is the case, then a full cooling-off
period of 15 minutes is required between this type of start.

4. For automatic (pilot device) operation, the motor should be allowed to cool for 15 minutes
between starts.

5. Input voltage, current and insulation resistance values should be recorded throughout the life of the
installation and should be used as a form of preventive maintenance.

6. Maximum number of starts per hour:

6”: 15 starts/hour
8”: 10 starts/hour
10”: 8 starts/hour
12”: 4 starts/hour
