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.).
Wrap three layers of waterproof tape on the connector, first from bottom up, then from
top down, and finally from bottom up. Start wrapping the connector at a position 50 mm
(1.97 in.) away below the bottom of the connector to the top of the connector, first from
bottom up, then from top down, and finally from bottom up. Cut off the redundant tape
after three layers are wrapped. Wrap each layer of tape around the connector tightly.
Wrap three layers of PVC insulation tape. Start the wrapping at a position 30 mm (1.18
in.) away below the bottom of the waterproof tape to the top of the connector, first from
bottom up, then from top down, and finally from bottom up. Cut off the redundant tape
after three layers are wrapped. Wrap each layer of tape around the connector tightly.
Start binding cable ties to the cable at a position 3 mm (0.12 in.) to 5 mm (0.2 in.) away
from one end of the PVC insulation tape.
