Use the following procedure to connect the grounding wire to the cabinet and route the ground wire to an
approved earth ground source:
1. Obtain a length of #4 AWG(25mm
2
) and resistance lower than 0.5Ω insulated green or
yellow-green colored copper wire as grounding wire.
2. Terminate one end of the wire with a ring terminal.
Figure 31 Grounding Wire the Ring Terminal
3. Secure the ring end of the wire to the ground stud.
4. Route the free end of the grounding wire to an approved earth ground source.
5. Cut the chassis grounding wire to length and connect it to the approved ground source.
4.4.2.2 Coaxial Cable Connections
The simplex low-power RF interface between the fiber CM-BTS/ANT enclosure and the single-band RU
enclosures is supported through RF SMA female connectors mounted on the enclosure chassis. The duplex
high-power RF interface between the single-band RU enclosures and the CM-BTS/ANT enclosure, and to
the service antennas, is supported through type-Nor 7/16 DIN female connectors mounted on the enclosure
chassis.
4.4.2.2.1 Fiber CM-BTS to Single-band RU
To connect the coaxial cable between fiber CM-BTS enclosure and single-band RU enclosure:
1. Obtain the required lengths of high performance, flexible, low loss 50Ω coaxial communication
cable for all coaxial connections.
2. Route the RF Tx path and Rx path coaxial cable between the fiber CM-BTS enclosure and
single-band enclosure interface and cut to the required length.
3. Connect the Tx and Rx cable to the designated Tx and Rx connector on the chassis of fiber
CM-BTS enclosure and the chassis of the single-band enclosure.
4. Dress and secure cable.
