yellow and black wires may also be terminated on
the protector ground post if desired.)

b) Carefully fit the cover assembly onto the base of

the protector, ensuring that no loose ends or other
wire pieces are protruding between the cover and

red and green conductors respectively to the
Ring-out and Tip-out terminals of the station
electronics assembly.

d) Run this wire to the protector or angle driver and

dress the end into the protector. Remove a portion
of the jacket and prepare the red and green
conductors to be spliced to the spade tipped red
and green conductors of the cover assembly of the
