1 Guidelines
The Franklin Electric submersible motors are a machine compo-
nent in accordance with the "machines" EC guideline. You must not
commission the motor until you have:
• manufactured a complete machine,
• met the safety requirements stipulated in the applicable EC
GB GB
2 Safety
The 4" submersible motor must only be operated in observance of
the following safety regulations:
•
• Take into account the implementation limits of motor and units
•
3)
• Protect electrical and mechanical danger spots against access
• Vent rising pipe before commissioning in order to avoid water
hammers when starting-up
• Provide a check valve in the pump or rising pipe (max. 7 m
•
•
tures only with derated motors
•
• Start: First the generator, then the motor
•
• After powering the system check:
• operating current of the motor at each phase
• mains voltage with the motor running
• level of the medium to be pumped
•
• Nameplate current is exceeded
• voltage tolerances of more than, 50Hz +6%/-10% ; 60Hz
+/-10%, compared to the rated voltage on the motor are
• dry run is imminent
3 Intended use
merged operation as drivers of variable torque loads such as pumps
i.e.
• Drinking water supply
• Wells in domestic houses, waterworks and agriculture
• Dewatering, pressure boosting, irregation systems
• Supply of process water
• Ground water heating systems
• Maximum 20 starts per hour, allow 60 seconds between
successive starts.
• The maximum submergence depth is 150 meters. Up to
1000 meters after consulting Franklin Electric. Motors in 316
SS are available for operation in aggressive environments.
The responsibility for correct material choosing lies with the
customer.
Improper use of Franklin Electric Submersible Motors, like pumping of
air or explosive media is strictly prohibited.
Attention
For required motor cooling, please consult motor
an inducer sleeve.
4 Transport and storage
Attention
The motor may be commissioned by trained and
instructed personnel only. Electrical connections
• Store motor in original packaging until assembly
• Under no circumstances may the motor be stored at tempe-

5 Connecting the motor cable
1. Remove plastic plug on the motor.
2. Clear plug and socket of dirt and moisture.
3. Apply a bit of silicone grease or vaseline to the rubber part of
the plug – pay attention that no grease reaches the electrical
contacts.
Motors with round plug:
4. Insert plug into the socket until the socket thread becomes

the thread. Then turn clockwise and tighten it by hand, until
compression of the rubber is noticed. Now, use a 19mm open
end spanner to tighten another ½ turn.
6. For all motor cables which fastened with two Phillips screws,
tighten screws with 4.5 - 5.0Nm.
4.
- 5. Lubricate the cable plug rubber with silicone oil. Insert the ca-
ble plug and push down to hard stop! Tighten the clamp screw
6.
7. Route the motor leads along the pump and use the cable
guard to protect it from damage.
6 Extending the motor cable
The cable provided can be extended by the customer, by one of
the following means:
• Apply non-permanent plug connection with Franklin Electric
Termination Kit 309 090 901 (or -902 with strain relief)
•
follow manufacturer's instructions).
designed for sub-
• Extension cable (Fig.: 25) must be approved for its use in the
medium and the prevailing temperatures.
7 Assembly of motor and unit
These instructions refer to the motor only. Please strictly observe
the assembly instructions of the pump manufacturer!
1.
2. Turn motor shaft by hand before assembly. It must turn freely
after overcoming the adhesive friction.
3. Apply acid-free, waterproof grease to the coupling internal
toothing.
4. Remove hexagon nuts from the studs of the motor.
5. Align the pump so that its cable guard is in line with the lead
exit of the motor and guide pump and motor together.
6. If deemed necessary, place spring rings on the studs and
tighten the nuts crosswise (max. 20Nm). Strictly observe the
tightening torques of the unit manufacturer.
7. Protect coupling spot against contact.
8 Electrical connection
enclosed data sheet. The following connection examples refer only
to the motor itself. They are no recommendation regarding the
control elements connected upstream.

Attention
The maximum tightening torque of the plug is 20
- 27 Nm. If the jam nut is tightened too much, the
plug will become leaky.
Note
The plumbers themselves are responsible for the
correct selection and dimensioning of the drop
cable!
Attention
Check radial and axial clearance of the motor
shaft. There must be no rigid connection since
otherwise motor and pump will be damaged duri-
ng commissioning.
