Installing and grounding the main drop cable
Perform this procedure to install the main drop cable, connect it to the ODU, and ground it
to the supporting structure.
Follow all instructions provided by the hoisting grip manufacturer. Failure to do
so may result in injury or death.
To install and ground the main drop cable, proceed as follows:
1 Hoist the main drop cable up to the ODU using the hoisting grip and a hoist line.
When the cable is in position and the grip handle is fastened to the supporting
structure, remove the hoist line.
2 Connect the top end of the long drop cable to the ODU (PoE port), as described in
Connecting an RJ45 and gland to a unit on page 5-19 .
3 Lay the main drop cable as far as the building entry point, ensuring there is
enough length to extend through the wall of the building to the LPU.
4 Attach the main drop cable to the supporting structure using site approved
methods.
5 Ground the drop cable to the supporting structure at the points shown in Figure 14
(mast or tower installation) or Figure 15 (wall installation), as described in Making
a drop cable ground point on page 5-22 .
A mast or tower may require additional grounding points, as specified in
Protection requirements for a mast or tower installation on page 2-18 .
