Installing the Subscriber Unit
2.
Spray the cable end and connector with SCC3 conformal coating and allow them to dry fully (approximately 3
to 5 minutes depending on the ambient temperature).
3.
Apply cold shrink or self-amalgamating tape to the connector end. For information about how to apply
these types of seals, refer to
Amalgamating
4.
Apply two layers of UV-resistant vinyl tape to the cable ends.
5.
Apply electrical insulation putty around the very end of the cable to form a seal between it and the base
station.
6.
If the subscriber unit is installed in a marine environment (e.g. wind farm substation, coastal tower, or marine
vessel) apply a coating of marine grease to all galvanized steel components, including mounting brackets,
nuts, washers and screws. This is in addition to the anti-corrosion spray applied during the mounting process.
IMPORTANT!
Should a cable need to be replaced, make sure all surfaces are thoroughly cleaned with a cleaner and
de-greaser spray before connecting the new cable. No residue from the previous weatherproofing
materials should be evident on the connector or the subscriber unit chassis.
Section 2.8.2
Applying Cold Shrink Tubing
To apply cold shrink tubing to a cable end, do the following:
1.
Disconnect the cable and slide the tube over the connector end.
2.
Reconnect the cable and slide the tube up to meet the subscriber unit chassis.
3.
Hold the tube against the subscriber unit chassis and start rotating it clockwise while gently pulling out the
core. Stop rotating once the front end of the cold shrink has begun to form around the cable end.
4.
Continue to remove the core in a counter-clockwise direction until it is completely removed.
Section 2.8.3
Applying Self-Amalgamating Tape
To apply self-amalgamating (or self-fusing) tape to a cable end, do the following:
IMPORTANT!
When applying self-amalgamating tape, make sure to stretch it to 2/3 of its original width to form a
tight seal.
1.
Cut a strip of self-amalgamating tape approximately 50 cm (19.7 in) long.
2.
Apply one end of the tape to the cable end and tightly wrap it around the cable once fully, making sure the
tape overlaps.
3.
Tightly wrap the remainder of the tape down the cable, making sure the tape overlaps with each pass.
4.
Repeat the previous steps to apply a second layer of tape.
