Cable Sealing and Wrapping

2.2.1 Water Tight Sealing

All external cable assemblies for the outdoor equipment MUST be properly
sealed to prevent water intrusion. Failure to achieve water tight sealing will
result in possible performance degradation and even product failure.
IMPORTANT: To maintain your product warranty, you must follow these guidelines and
recommendations during equipment installation:
•
Ensure all external connections to the equipment are hand-tightened and wrapped with a
self-amalgamating tape such as 3M Type 23 Scotch Self-Amalgamating Tape (or
equivalent). The sealing must cover the external connector housing and extend beyond
the end of the heatshrink that covers the connector termination of the cable assembly.
•
Squeeze the self-amalgamating tape tightly and make sure both ends of the tape have
formed around the connector and cable to create a water tight seal.
•
ALL unused external connectors MUST be covered with caps and sealed. Make sure to
inspect the connector cap rubber seal for cracks before using.
2.2.1.1

Customer Cable Water Tight Sealing

Should you receive an accessory kit that contains only the mating cable
connectors, or if you (the end-user) choose to supply your own cables and
connectors, CEFD strongly recommends that you use an adhesive lined
heatshrink such as TE Connectivity #ATUM-24/6-0 (or equivalent) to cover the
connector strain-relief area. Your sealed, water tight cable ends should appear
as per this example:
System Connectors, Installation, and Startup
Low Power Outdoor (LPOD) Amplifier/Block Up Converter (BUC)
