8. Figure 35 below, illustrates the connections of the drop cable to the connector
blocks inside the Junction Box. The diagram shows the order of wire insertion to
ensure that the cables fit in the junction box. When connecting the thick stranded
wire ensure that the screws are fully undone and the hole fully opened to allow the
wire to be inserted without displacing strands. A wire loop should be inserted
between tags 3 & 4.

connected to the same Tags as the wires from the CRU. Run and connect the cable
from the PSU to the Junction Box.

cables with tie wraps.
