6.12. Waterproofing Without Using a Cold-Shrinkable Tube
If installing a cold-shrinkable tube fails, use off-the-shelf self-bonding tape to provide the
waterproofing.
(1) Securing the small Lid of the WT and the spacer
Using an appropriate length of self-bonding tape, wrap the tape around both the small Lid of
the WT (at its base) and spacer one complete turn. After one turn, wrap about seven turns
around the Ethernet cable by overlapping one-half of the previous turn. Reverse the wrapping
direction and wrap about another seven turns back to the small Lid.
・
For the stretching margin of self-bonding tape, see the instruction manual for the
product.
・
When wrapping self-bonding tape, start at the base of the small window and end at
the end of the waterproof sleeve. Next, reverse the direction and end at the base of
the small window. This procedure makes an attractive wrapping and improves the
waterproof effect by making any air pocketsless likely.
・
Overlapping the wraps also protects against air pockets.
・
Press evenly along the entire length of tape to remove air pockets.
・
Make sure that there are no air pockets between the self-bonding tape and the small
window of the WT or the rubber bushing. Air pockets will degrade the waterproofing
effect.
