Before wrapping waterproof tape, stretch the tape evenly until the length of the tape becomes twice
its original length.
Do not stretch the PVC insulation tape when wrapping the PVC insulation tape.
Wrap each layer of tape around the connector tightly and neatly, and ensure that each layer of tape
overlaps more than 50% of the preceding layer. Ensure that neighboring layers are stuck to each
other.
Ensure that the adhesive surface of the tape overlaps the lower layer.
When cutting off the cable ties, reserve a redundant length of 3 mm (0.12 in.) to 5 mm (0.2 in.).
