1. Applications
Grundfos cable termination kits, type KMA, are specially
designed to join the motor cable and the submersible drop cable,
both single-core and multi-core cables, during installation of
submersible pumps.
The Grundfos cable termination kit can be used for cables made
of polyethylene, PVC, synthetic or natural rubber, etc. for
voltages up to 1000 V and ranging in size from 1.5 mm
2
120 mm .
2. Cable termination kit
The termination kit is available in two versions:
• with detachable plug
• without detachable plug.
Please read the section below corresponding to the selected kit.
2.1 Cable termination kit with detachable plug
This kit is available in several versions, depending on the number
of leads and the cable size. Furthermore, the kit is available with
a built-in overvoltage protection device.
The figures referred to in the following text can be found in the
appendix at the end of these instructions. Where two drawings
are shown, the drawing to the right illustrates a cable joint with
overvoltage protection device, e.g. fig. 1.
2.1.1 Preparation
This preparation section refers to the Appendix on page 26.
– Make sure that the submersible drop cable is not connected
to the mains.
– Unscrew the tube (A) from the plug (B), fig. 1.
– Strip the submersible drop cable (D), fig. 2, and cut off the
leads in a staggered manner so that they correspond to the
leads on the motor plug (B), fig. 1.
– Both cable sheath and leads must be completely dry.
– Clean and sandpaper the stripped leads and that part of the
insulation which will be covered by resin. Dirt or grease
must not get into contact with the sandpapered surfaces.
– Push the tube (A) over the submersible drop cable, fig. 2,
making sure that the threaded end is pointing towards the
stripped cable end.
– Pull the insulators (F) off the connectors (S) and fit them on
the leads of the submersible drop cable, fig. 2.
– Fit the appropriate lead of the submersible drop cable into
each of the connectors (S), fig. 3.
– Push the insulators (F) over the connectors, making sure
that they are properly covered and insulated, fig. 4.
4
– Arrange leads, connectors and overvoltage protection
devices, if fitted, so that the tube (A) can easily be pushed
over the joint.
– Push the tube (A) over the joint and screw it firmly onto the
Page
plug (B), fig. 4.
4
– Make sure that the submersible drop cable sheath is at least
4
50 mm inside the tube (A), fig. 4.
4
– Suspend the submersible drop cable with the joint vertically,
4
making sure that the connectors are arranged correctly
5
inside the tube and that the submersible drop cable is
5
centered. The tube can now be filled with resin.

2.2 Cable termination kit without detachable plug
This kit is available in several versions, depending on the number
of leads and the cable size.
The figures referred to in the following text can be found in the
appendix at the end of these instructions.
2.2.1 Preparation
This preparation section refers to the Appendix on page 26.
– Make sure that the submersible drop cable is not connected
2
to
to the mains.
– Make sure that the motor cable is so long that the cable joint
can be fastened to the riser pipe above the pump
connection.
– Cut off the tapered end of the tube (A) until the tube
diameter and the submersible drop cable diameter are
identical.
– Cut off and strip the motor cable (M) and the submersible
drop cable (D) in a staggered manner, fig. 6.
Make sure that both cable sheaths are at least 50 mm inside
the tube when this is pushed over the joint, fig. 8.
– Both cable sheath and leads must be completely dry.
– Clean and sandpaper the stripped leads and that part of the
insulation which will be covered by resin. Dirt or grease
must not get into contact with the sandpapered surfaces.
– Push the tube (A) over the submersible drop cable, tapered
end first, so that it is free of the stripped cable end, fig. 6.
Fit the rubber plug (G), if supplied, on the motor cable and
push it upwards. The cylindrical plug end must point
towards the stripped cable end.
– Push an insulator (F) over each motor cable lead, fig. 6.
– Fit and tighten the connectors (S), fig. 7.
– Push the insulators over the connectors, making sure that
they are properly covered and insulated, fig. 8.
– Tie up the leads by thin strings between the first and the
second and between the third and the fourth connectors, to
ensure that the leads are centred in the tube.
– Push the tube (A) over the joints until these are positioned in
the middle of the tube. Both cable sheaths should be at
least 50 mm inside the tube, fig. 8.
– Wind one piece of the adhesive tape tightly around the
tapered end of the tube and the submersible drop cable and
press firmly to ensure a perfect seal.
– Suspend the submersible drop cable with the joint vertically,
making sure that the connectors are arranged correctly
inside the tube and that the submersible drop cable is
centered.
The tube can now be filled with resin.
