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.
4. Insert plug into the socket until the socket thread becomes

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.
6. 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

Note
The plumbers themselves are responsible for the
correct selection and dimensioning of the drop
cable!
Extension cable must be approved for its use in the medium
and the prevailing temperatures.
7 Assembly of motor and unit
7KHVHLQVWUXFWLRQVUHIHUWRWKHPRWRURQO\3OHDVHstrictly observe
the assembly instructions of the pump manufacturer!
1. 3ODFHPRWRUDQGSXPSKRUL]RQWDOO\DQGOHYHO¿J
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 rings on the studs and tighten
the nuts crosswise. Strictly observe the tightening torques
of the unit manufacturer.
Attention
Check radial and axial clearance of the motor
shaft. There must be no rigid connection since
otherwise motor and pump will be damaged
during commissioning.

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
