Extension Of Cable - Grundfos DPI Installation And Operating Instructions Manual

6.1 Extension of cable

The DPI kit 2 enables the extension of the sensor cable to up to > 30 m.
If extension of the cable is required, always follow the guidelines below to
ensure optimum connection between sensor and controller. The six steps
below refer to fig. 4 on page 12:
1. Remove the outer insulation 50 mm from each cable end. Pull the outer
screen away from the cable ends.
Shorten and strip the individual conductors as shown.
2. Cut 1 ∅10 shrink-on sleeve and 4 ∅3 shrink-on sleeves in lengths of
20 mm.
3. Place the shrink-on sleeves as shown in fig. 4. Solder together conductor
ends of the same colour.
4. Place the small shrink-on sleeves over the centre of each solder. Heat up
the shrink-on sleeves from the centre and outwards using a heat gun in
order to achieve the best result.
5. Hold the conductors close together and pull the outer screens over the
joint, one screen at a time.
6. Place the big shrink-on sleeve over the centre of the joint and shrink it
using the heat gun from the centre and outwards.
