Understanding grounding requirements
Connection of the cabinet ground wire and the lightening ground wire to external earth ground systems that
meet all relevant codes and requirements is required.
Beyond the lightning ground wire and the cabinet ground wire, the following additional and optional ground
connections are available and may be utilized as required and appropriate at each site:
• Three pairs of dual lug holes with 1/4-20 threads. See Figure 3
on page 5 and Figure 4 on page 7,
• A third wire ground connected at the power terminal to provide a grounded link to an external power
cabinet.
Understanding external connections
During installation, you must connect the IP-RN 8000 to a range of external cables. Procedures for making
these cable connections are spread throughout this book. For an overview of the complete installation
procedure, see Chapter 2,
Installation process.
Table 18
lists all connections that must be made and provides additional information.
WARNING
Grounding must be performed according to all relevant electrical
codes and requirements. The site planner must review grounding
requirements and determine the grounding plan accordingly.
Failure to provide adequate grounding can result in damage to
equipment and danger to personnel.

Cable Description
Power cable External input ranging from 24 V DC to 29 V DC, 27 V DC nominal at the
cabinet power terminal
See Table 28
on page 193 for power specifications.
Ground connections Provides grounding for safety and equipment protection.
A main ground is required.
Additional optional grounding connections can also be installed.
See Understanding surge protection and grounding
on page 33
See Table 29
on page 193 for grounding specifications.
RF antenna cables There are two basic antenna configurations per sector.
• The main receive (RX0) and the transmit (TX) can be combined on a
single antenna cable and the diversity receive (RX1) can be on a second
antenna cable
• The main receive, the transmit, and the diversity receive can be on
separate cables.
Antenna cables feed into the IP-RN 8000 through the Rox System cabinet
seal and must be connected internally to RF surge suppressors.
See Table 32
on page 194 for cable specifications.
