3. Installation 3. Installation Preparation Location Care must be taken when selecting a site for the installation of a C3. It should have a clear aspect (down to the horizon and 90 degrees either side of the optimal IFBEJOH TFF BQQFOEJY " UP BMMPX UIF TPMBS QBOFM UP HFOFSBUF TVGæDJFOU QPXFS UIJT is particularly crucial during the winter months. To allow the radio communications to operate effectively the C3 should also be situated away from large metal structures such as sheds and windmill towers.
C3 User Guide antenna at a greater height above the ground if required. Greater pole diameters can be used if this is not a requirement. Pre-cabling It is prudent to consider the routing and protection of equipment cables prior to installation. Cable is best protected above the ground by the use of rigid electrical conduit (20 or 25 mm works best). This can also be used below ground in the absence of specially designed direct-burial cable (see appendix A2 for more information).
3. Installation • • • • Un-fasten and tighten a hose-clamp around the mounting pole. Mark the band approximately 15 – 20 mm past the worm-screw (Figure 6) Cut three hose-clamp bands at this point using tin-snips or equivalent tool Fix the mounting bracket to the pole using three hose-clamps. The worm screws should be internal to the bracket (Figure 7-2) 1 2 1 - Mounting pole 2 - Hose-clamp (x3) 3 - Rear cable entry pilot mark 3 Figure 7.

4. Appendix 4. Appendix A1. Electrical connections Equipment and power connections to the C3 module are made via 4-way 3.81 mm pluggable screw terminal blocks, with the exception of the DC jack power input (typically used when supplying power via a 240 VAC wall plug pack). RF antenna connections are made via SMA and BNC connectors. The following describes these connections and the relevant connector pin assignments for each function.
