a. Removal

(1) Disconnect coaxial cables (6) at cable inputs 1 and 2 connectors on processor assembly. (Figure 3-70)

(2) Using diagonal cutting pliers, cut coaxial cables (6) (Figure 3-71) as close to retainer cap (5) as possible.

(3) Using diagonal cutting pliers, cut tie wrap (1) and remove junction splice assembly (2) or terminator assembly

(11) from fence.

b. Installation

(1) Remove knockout hole from retainer cap (5).

(2) Insert both cables or cable through cap holes (larger holes for insensitive cable).

(3) With a wire stripper, strip back outer insulation of coaxial cable(s) (6) approximately 1 inch (26 mm).

(4) Cut and fold braided shields (7) back over outer insulation by 0.25 inch.

(5) Strip center conductor insulation (8) to 0.5 inches (13 mm).

(6) Remove PWA (10) shield retainer (4).
