2.4 Chassis Ground Connection

A stud is provided on the rear side of the chassis for connecting a grounding wire to the
chassis. Use the following procedure to connect the grounding wire to the chassis and to route
the grounding wire to an approved earth ground source:
1. Obtain a length of #18 AWG (1.00 mm) insulated stranded copper wire for use as a
chassis grounding wire.
2. Terminate one end of the wire with a ring terminal.
3. Locate the chassis ground stud at the rear of the RIU as shown in Figure 8.
4. Attach the ring end of the wire to the chassis ground stud (see Figure 8).
5. Route the free end of the chassis grounding wire to an approved (per local code or
practice) earth ground source.
6. Cut the chassis grounding wire to length and connect it to the approved ground source as
required by local code or practice.
Note: Be sure to maintain reliable grounding for rack and wall mounted equipment. Pay
particular attention to ground source connections.

2.5 Coaxial Cable Connections

The RF signal connections between the RIU and DHU are supported through a pair of type N
female connectors mounted on the RIU front panel. One connector is used for connecting the
forward path coaxial cable and the other connector is used for connecting the reverse path
coaxial cable. The RF signal connection between the RIU and the donor antenna is supported
through a single type N female connector. The single connector is used for connecting the
coaxial jumper cable that links the RIU to the donor antenna.
