GENERAL INFORMAT ION- Check that the kit is suitable for the cable type.
- Check the materials listed in the bill of materials for completeness.
- Read the installation instructions carefully before starting the installation.
- Install carefully and make sure the materials are clean during the installation.
- Clean the working place after the installation.
GENERAL INSTRUCTIONS FOR HEAT SHRINKING- Please note that in some working places a hot work permit is needed.
- Use a propane burner with a flame length of approx. 20-30 cm. Do not use too large or sharp flame.
- Move the flame all around the cable on the shrinking direction. Move the flame continuously to avoid overheat-
ing.
- Make sure that the ventilation is good and there are no flammable materials around.
- Clean the cable surfaces before shrinking.
- When shrinking, always follow the installation instructions and the relevant sequence to avoid trapped air.
- Check that the tube has shrunk evenly around the cable before you continue shrinking.
- If the tube turns around at the end of shrinking, straighten the tube by directing the flame inside the tube from
the opposite direction.
- After shrinking the tubes should be smooth and even following the shape inside.
LEGAL NOTICE- The product must be installed only by a competent person with sufficient training in installation practices and
with sufficient knowledge of good safety and installation practices in respect of electrical equipment. If local leg-
islation contains provisions in respect of such training or sufficient knowledge in respect of installation of electri-

4 TO 4 CORE JOINTS
1. Put the outer sealing tube to either side of the cable. Straighten the cables with a 200 mm overlapping to each other. Cut the cables following the center line (reference line). Peel the cable outer sheath for the length of dimensions A & B (Armoured cables A/B+30mm).
ARMOURED CABLES
2. Roughen the armour (30 mm) with grinding paper or steel brush and clean it.
Wrap few layers of PVC-tape to the sharp edge of armouring to prevent it to open. Remove the armour up to 30 mm from the outer sheath.

3. Roughen the outer sheath of both cables of around 150 mm starting from the peeling point and clean them. Place the insulation tubes on the B side of the joint.
Remove the insulation of the conductors up to length X = half of the connector + 10 mm. Brush the bare conductors. Install the connectors following the manufacturer’s instruction. If the conductor size is smaller than the minimum accepted conductor size for connector, use the filler piece included in the kit inside of the connector (with 70 mm² and 120 mm²).
4. Clean the connectors and cores with a cleaning tissue. Use a socket wrench or a socket key to tighten the bolts. Tighten first the two outermost bolts half way and continue then to the other bolts. Support the cable joint with a holding tool. Tighten the bolts until they break. You may need to slip the insulation tubes from side to side during the tightening process.
5. Centre the inner tubes on top of the connectors. Shrink them starting from the centre.

ARMOURED CABLES: CONNECTING THE ARMOURING
6. Clean the armouring with a cleaning tissue. Fix the tinned copper braid on the armouring with constant force spring.
Constant force spring: Turn first one turn of constant force spring on the copper braid. Fold then the tail of the braid over the
constant force spring and finish the tightening of the spring. The extra tail of the braid can be taped together with the original braid. Tighten the spring by hand and wrap some pvc -tape over it to keep it tight.
Connect the other end of the long copper braid in a same way as the first one.
7. Wrap two layers of sealing mastic from the crutch to 20 mm over the outer sheath.
ALL CABLES
8. Centre and shrink the outer tube starting from the center. Remember to let the joint to cool down be-fore applying any mechanical load.
9. The joint is finished and ready to use, but let it cool down before loading it mechanically.
