PRELIMINARY
Site Requirements
The enclosures are mounted according to the site documentation. Refer
to Figure 2-10, Figure 2-13 through Figure 2-15 for dimensions and
clearances and spacing information.
Figure 4-32 shows an example of a mounted single system outdoor
grounding diagram. Figure 4-33 shows an example of a mounted
multiple unit system outdoor grounding diagram.
Outdoor Grounding Procedure
Follow the procedure in Table 4-25 to set up a site for grounding.
Table 4-25: Procedure to Ground an Outdoor Site
Step Action
1 If not already known, consult site documentation for location to mount system.
2 Verify that all master ground for the system is in place.
3 Follow the procedures as described in Chapter 4 for installing the PDE, TME, and cCLPA.
4 Once installation is complete, ground the Primary PDE to the system master ground.
5 Route grounding cables from the other enclosures to the Primary PDE. Apply anti–oxidant grease to
ground lugs and connections.
* IMPORTANT
In order to route the TME to PDE Earth ground cable through the power conduit, a jumper cable must
be spliced from the conduit ground bushing to the earth cable.
6 Ground the cCLPA to the system master ground. Apply anti–oxidant grease to ground lug and
connection.
7 Ground the antennas to the system master ground.
8 Once grounding is completed, layout conduit or solid shield RF (SSRF) cables.
9 Route wires from PDE through conduit or route SSRF cables to the TME.
10 Route Data cabes from the TME to the cCLPAs.
11 Route AC power and battery backup (if used) to PDE.
12 Route DC power from PDE to cCLPA and TME.
13 Perform the procedures described in the remainder of this Chapter.
