1:1 Redundancy System Cabling and Installation
Figure A-3 shows the schematic diagram for cabling 1:1 Redundancy applications. For any 1:1
Redundancy System setup, care should be exercised in cable installation:
• Install the cables using the most direct route – avoid all sharp bends.
• Secure all cables with clamps and ties.
• Cable connectors used in outdoor applications – Type ‘N’ connectors and military style (MS)
connectors in particular – must be sealed to avoid moisture seepage. Moisture can seep
into junctions at the plug end of the connector, between the fixed and movable parts, and
where the cable connects to the connector. In the presence of such seepage, signal
attenuation and possible loss of signal can occur. Therefore, seal all cable junctions with a
self-amalgamating tape, such as 3M Type 23 Scotch Self-Amalgamating tape, or equivalent.
For details about the cables used in both Standalone and 1:1 Redundancy applications, see
Appendix B. CABLE DRAWINGS.
