1. As shown in the gure, peel o the shields from the rubber/wire
of the power cable.
- Peel o 20 mm of the wire shields of the tube installed already.
2. Insert both sides of core wire of the power cable into the connection sleeve.
3. Using a compressor, compress the two points and ip it over
and compress another two points in the same location.
- The compression dimension should be 8.0.
- After compressing it, pull both sides of the wire to
make sure it is rmly pressed.
4. Wrap it with the insulation tape twice and position your
contraction tube in the middle of the insulation tape.
5. Apply heat to the contraction tube to contract it.
6. After tube contraction work is completed, wrap it with the
insulation tape to nish.
