Coaxial
Cable
Protection
The coaxial cable must be properly handled prior to and during
installation. Improper handling may result in cable damage and
require cable replacement. Use the following guidelines when
handling the coaxial cable:
D Keep the cable ends tightly sealed (e.g., with cable caps)
during storage, transportation, and installation of the cable.
Keeping the cable ends sealed helps prevent exposure to
moisture or other foreign matter.
D Do not exceed the minimum bend radius of the cable during
storage or installation. Refer to Appendix C for cable
specifications. Bending the coaxial cable sharper than the
recommended minimum bend radius may decrease the
reliability of the network.
D Prevent the cable from contacting abrasive surfaces such as
concrete.
D Follow the cable pulling recommendations specified in
section 7.3.
Electrical
Isolation
Use the following guidelines when installing the coaxial cable to
ensure electrical isolation:
D The exposed metal parts of the AutoMax network cable
system components (BNC connectors, adapters,
terminating loads) must not come in direct contact with
electrical conductors (including electrical enclosures,
AutoMax racks, tap shells, conduits, etc.). If necessary,
shield these components using insulating jackets, heat
shrink tubing, or electrical seal tape.
D The network coaxial cable must be installed in a separate
metal conduit. This conduit must be properly grounded
along the entire length.
D The network coaxial cable must not be installed closer than
1 m (three feet) away from electrical motors, generators,
transformers, arc welders, rectifiers, high voltage lines,
induction heat sources, and sources of microwave radiation.
D If grouping the network coaxial cable with other cables and
you cannot avoid wires, you must comply with the
recommendations provided in the ANSI/IEEE Standard
518Ć1982.
D Grounding, lightning, and surge protection of the network
cable system and attached equipment must comply with the
requirements of applicable codes.
